All Units:

Can I send a unit back to the factory for service or repairs?

Absolutely! Anyone can send equipment to Rane for repair work, maintenance or testing, so long as a return authorization (RA) number is obtained before the item is sent. Units shipped from outside the U.S. may incur exorbitant import duty and landing charges so we suggest non-U.S. customers contact their appropriate International Distributor. We quote estimates for non-warranty work only by model number, at the time the RA is given. Once the equipment is received, it is worked on within a matter of days. No further estimates or quotations are given regarding work, unless the parts and labor will exceed the original dollar amount by 10 % or more.

If you want to request a return authorization (RA) number, provide all this information:

Your unit's serial number
Your and/or your company's full name
Your return shipping address
Your telephone number
Detailed description of the problem

With this information in hand you may then request an RA number from Service. Any requests not having complete information will not get an RA number. Units cannot be returned to the factory without return authorization numbers! When returning units for service, do not send the power supply or any other accessories unless instructed to do so. Also do not ship units in road cases, racks or any other containers. Use a standard issue, garden-variety corrugated walled cardboard box (see below) and have a professional packing agent handle transport and cartage. It will save your unit from shipping damage, which is not covered by warranty.

I need to modify a unit. Who do I talk to about this? And / or I have a modified unit and need to get it serviced, where can I take it? Also: I want to modify a unit for automotive use, how much do you charge for this service?

Modifications are against company policy, with very few exceptions. The ones we authorize and condone, as well as support are listed in the respective manuals or on our website. We do not support any automotive applications nor provide information to the do-it-yourself crowd for reasons of liability. Units which have been previously modified whether correctly or not, can be sent to the factory and returned to stock condition. We do not preserve unauthorized modifications or restore malfunctioning ones. This type of work needs to be sent to a custom shop or specialty technician. We do not have lists of this type of personnel nor do we support work in this area, (i.e. if it isn't stock, you're going to have a hard time getting support for the unit, unless you want it reverted back to original factory condition).

I need a schematic and / or manual for a unit, but don't see it on your website. What can I do?

Most products have documentation available on our site. The older units are listed in the Library section under Discontinued Products. If you don't see your unit listed, check there. Every letter in the model designation makes a difference, so be sure to view the exact same documentation for your particular unit, (i.e. don't use an MP 22z manual if you have an MP 22). The relevant documents are: Data Sheets for specifications and block diagrams, Manuals for operational details and instructions, and Schematics for internal wiring diagrams and circuitry references. Schematics for some units contain proprietary information which may not be completely divulged for confidentiality reasons.

My unit has one a line-lump power supply and the manual makes references about properly grounding the unit. How do I do so?

Units with external power supplies (the Rane RS 1 for example) do not get grounded through the power cord. Since no third prong exists on the AC power plug, you must connect a separate wire to the small silver screw on the rear of the unit -- look for the Rane warning tag -- and attach the other end of this wire to a good known earth ground. Some examples of this are: a steel AC conduit, cold water pipe, steel building girder, the center screw on an outlet or any other unpainted metal surface emanating from the foundation. Painted rack rails do not work, nor do rusty pieces of metal or those items which don't connect directly to the earth. When in doubt, have a licensed electrician verify the grounding. All too often our Technical Support Department receives calls about units damaged because they weren't properly grounded. Don't take chances, follow the directions completely.

I've got to send a piece back, but don't have the original box. How should I pack the item?

Very carefully seal the unit in a plastic bag, (a garbage bag works well) and then wrap the unit with large type bubble wrap. Make sure the item is covered on all sides by at least two inches of material per side. If you must use styrofoam peanuts, then be sure to compress the packing very tightly. We receive units every week which have received damage from insufficient packaging. This type of repair work is not covered by warranty and is typically very costly. Before sealing the carton, write your

full name
address
telephone number
equipment model number(s)
serial number(s)

on a piece of paper and enclose it with the product(s). It is also very wise to include any specific details relating to symptoms or problems you are having, with the item being serviced. This can same a great deal of time on the bench and that means lower total repair costs.

I need a part (fader, "telephone-type power supply", knob etc.) for my unit, but I can't get the dealer to order it. What do I do?

Customers can order parts directly from the factory by calling (425)-355-6000 between 8 and 5 Pacific time, weekdays. Alternately you can email your request to Customer Service. All orders or inquiries must have the serial number. Parts orders can only be taken for customers in the U.S. International correspondence should be directed to your International Distributor. Tip: When ordering parts, describe the piece exactly as it is on the product. (Example: Master Slide Pot; PCB Mount Headphone Jack; Phono 1 RCA Jacks.)

Where do I find the serial number on my unit? What does it look like?

Rane product serial numbers have taken on various forms over the 20 plus years we have been manufacturing units. In the very early days, units contained part of the model number within the serial number, and all of this type start at 1002. A period separates the model letters from the serial numerals, (Examples: AC3.2345 is an AC 23 from 1986, MP.1234 is an MP 24 from 1986 and ME.3333 is an ME 15 from 1987) These are found on a vinyl silver sticker, with black print about 1 1/2" wide and 3/8" tall. There may be as many as five digits after the model designation. The date code is a separate similar tag but only 1/2" wide by 3/16" tall. Numbering represents the manufacturing quarter of the year the piece was made, (Examples: 1-88 is January, February or March of 1988, 4-90 is October, November or December of 1990). Starting January of 1999, we changed to month codes. (Examples: Later smaller sticker 2-99 means February 1999 and 9-99, indicates September 1999). Silver tags were installed on either rear or side panels as matched pairs. On March 15, 1994 we changed to nonsensical serial numbers, dropping the model number from the nomenclature. The first of this type is serial 30001, (an AD 22 for those interested --- having a date code of 1-94). Finally, in October of 1999, we changed to a white thermal paper bar code sticker, listing both serial number and date code together. Isn't togetherness better? These are mounted on the side of the unit. Dimensions are 2 1/2" high by 1 1/2" wide. Each has (21) before the eight digit serial number (Example: (21) 00333333 [an ME 60 from August 2001]). Serial numbers are the bottom row of digits on the bar code decal. So for all those looking at used gear, be aware of what the date code can tell you. Also be specific and complete with regard to model numbers: an MP 24 is significantly different from an MP 24z. Likewise an AD 22 and AD 22d share very little in common with regard to circuitry. Do not tear off or alter serial number tags: it voids your warranty. To the purchaser of used gear we say: "caveat emptor" (let the buyer beware).

Can I use more than one set of outputs on my unit? How much signal loss will occur if I do?

When multiple outputs are used, or a Y-cord is connected to drive parallel inputs, under the vast majority of situations no signal loss will occur. For the technically inquisitive, a minimum load impedance of 10 times the source is recommended. Most Rane outputs are 100 ohms per leg balanced, so net impedance limit is 1,000 ohms (or 1K). You may safely use all outputs at once, with the only concern being mixed mode wiring with balanced and unbalance combined can contribute to ground loops (i.e. low level hum in the system).

I saw a Rane unit recently with rubber knobs and different cosmetics. Can I change the knobs on my older unit to the new style?

Unfortunately no. When we updated the look of Rane products we changed to a different style knob (called a Flexi-fit) which will not fit the older units. Controls and artwork have changed and evolved. Like most anything change eventually happens and we thought it was time for a new look. Sorry to those who are confused or inconvenienced, but units with older knobs are still just as good as their newer counterparts.

I'm buying a unit in the U.S. take back home overseas and need to get it in 230 volt version, how do I do this?

This type of purchase is called a gray market transaction. Warranty on Rane products only applies in the country of purchase and U.S. models only ship with 120 VAC power supplies. Units taken out of the U.S. do not have warranties in the destination country and some distributors may not offer any parts or service support. This is their option. Rane discourages gray market purchases and highly recommends that customers buy Rane items in their home territory, due to a multitude of reasons. Be forewarned that saving a few bucks on the purchase price is easily wasted the first time service is needed. Certain Rane units are Factory Service Only and since the distributor is the only one who can repair them (or send them back to the factory for repairs) gray market units come with substantial limitations. Support your local agents; buy locally.

Does the unit come with Euroblock connectors and / or Does it come with the remote power supply? (Are all the accessories included?)

Yes. All Rane products using Euroblock connectors (a k a Phoenix plugs) come with the required connectors to hook the unit up. The same holds true for any Rane unit which requires an external power supply; it is included with the product. Audio cabling is the only element not included with a new unit. Only units which use an RS 232 cable may require and additional purchase. We ship an 18" cable for "jumping" multiple units, but may be shorter than practical for connecting the computer.

What is the maximum BTU / Hour produced by model [ insert model here ]?

To calculate maximum BTU / Hour, multiply the input power rating in watts on the rear panel of the unit (or on the external power supply, [i.e RS 1]) by 3.41. Example: RPM 88 is rated at 55 watts AC, therefore we expect a maximum of 187.55 BTU / Hour.

How hot / cold / wet / high can I make my unit?

See our Environmental Specifications.

AC 22 / AC 22B / AC 22S:

Can the unit be modified for constant directivity horn equalization?

This is a simple modification that requires installing a specific capacitor on the pre-drilled circuit board, determined by your CD horn rolloff point. Download this PDF note.

I need to move the delay circuit, but I cannot find the jumpers listed?

The current version AC series crossovers use SMT (surface mount technology) devices and therefor we had to eliminate the delay transplant modifications. All possible options are here: Crossover Modifications. Note: not all versions can accept changes. Some do not offer any configurable options.

AC 23 / AC 23B / AC 23S:

How can I get my AC 23 crossover point below 190 Hz in 2-way stereo mode?

The AC 23 is not designed for 2-way operation below 190 Hz. You can "fake it" by using a summing Y-cable (check out Why Not Wye?) on the mids and highs in 3-Way mode. This allows you to use the Low/Mid (70 - 1 khz) filter for the lows. If you're really adventurous, you can modify the filter limits. Download this PDF note on Crossover Modifications.

I need to move the delay circuits but my unit doesn't match the layout in the manual.

Earlier AC series units do not have all the flexibility of later ones. Thus not all features exist in every variant. Additionally the current versions using SMT devices do not offer the delay transplant option. It is not viable within the design architecture presently utilized.

My AC 23 doesn't have the 2-way / 3-way switches on the rear panel, how can I run it in 2-way mode?

Earlier AC 23 units did not offer 2-way mode operation. They run 3-way stereo, 4-way mono and 5-way mono only. Externally combining a pair of signals -- mids and highs or mids and lows -- provides a means to achieve 2-way functionality. As above, the summing Y-cable is used to mix two signals together, (see Why Not Wye?).

My AC 23 is in 3-way mode but there are no highs in channel 2 and no mids in channel 1.

The AC 23 has switching jacks and must have connectors plugged into every jack (as shown in the AC 23 manual) for the configuration being used. This is the most common call we get. Try plugging connectors into all of the outputs, then verify their operation.

AVA 22d:

I hooked up the AVA 22d but don't get unity gain through the equipment.

If you are running the product in certain types of broadcast environments you may need to add 600 ohm termination resistor(s). If the device feeding the AVA 22’s input has a 600 ohm output impendance, and the load on the AVA 22’s output is also 600 ohms (i.e., you’re interfacing the AVA with video gear’s audio I/O), changing the output resistors R70 & R69 to 300 ohms allows the same level to be passed while the AVA 22 is bypassed or processing the audio signal. Read the 600 Ohm User Information note in the manual for additional details.

BB 22 / BB 44x:

Will the unit work in reverse (i.e. is it bi-directional)?

Yes. The products do not have a required signal flow. Simply use the inputs as outputs and vice versa. Note: The OPTION 88 works exactly the same as the BB 44x, since the same assembly is used.

CP 52 / 64 / 52S / 64S:

Are the CP 62 remotes compatible with the CP 64?

No. The CP R1 and CP R2 only work with the CP 62. The proper remotes for the CP 64 series are the PR 2 for paging, and the ZR 1 for source and level control.

How can I hook a fire alarm control relay to the unit for complete muting?

Connect a normally closed relay across the Paging Inputs (plus [+] and minus [-]) so they are shorted together. When an alarm condition exists and the coil becomes energized, the contacts open and the short is removed. The Paging Input Detect Threshold must be adjusted such that the noise floor is sufficient to trigger a paging condition and enable ducking, (i.e. set the detector just shy of maximum sensitivity --- fully counter clockwise --- so shorted turns off the green LED and open causes it to illuminate). Front panel Ducker Depth control is adjusted to fully counter clockwise so no program material is audible during an alarm condition.

What are the EXPAND OUTPUT connections for?

These fixed line level outputs are for driving other systems or "stacking" CP 64 series and CP 52 series together for larger applications. The signal may consist of paging only, program only or a copy of the zone signal. This output can be used for music on hold as well as zones not needing level adjustment (i.e. rest rooms, entryways and similar areas).

What type of wire can I use to connect the remotes?

For runs up to 200 feet any five conductor wire, 22 gauge or larger, will suffice. Use shielded wire for distances greater than 200 feet.

Can Zone 1 of the CP 64 operate in Mono mode?

Yes. The CP 64 series has a Zone 1 Mono Switch located internally, refere to manual for specific location.

When Zone 1 of the CP 64 is in Mono mode, which outputs LEFT or RIGHT should I use?

Either output will provide a summed LEFT plus RIGHT mono signal. You can use both LEFT and RIGHT outputs simultaneously when needed, (like when you want to run two channels on a power amplifier without connecting a Y-cord.)

When the Priority Signal finishes playing, it takes too long for the music to fade back in. Can I adjust this?

Yes. The internal Program Priority Release Time control, located near the Line 2 and Line 3 RCA input connectors, can be rotated to change the interval from five to twenty seconds. Clockwise rotation increases the release time interval.

I just want a remote volume control, not source selection. Is there a way to do this?

All selection and level is done either on the front panel or at the remote; never both locations. Connecting just a VR 1 to the CP 64 or 52 remote control terminals will allow level adjustment. However without a source selector the unit will default to source one. If the PRIORITY / L4 INPUT automatic switching is enabled, then the unit will select the L4 signal when present and L1 at any other time. Thus if only a jukebox (P/L4) and other line source (L1) are used, the remote volume control will work just fine. Refer to the CP 52 and CP 64 documentation as well as the ZR 1 literature for clarification.

I just installed a unit and don't get audio. Or I hooked up the ZR 1 source remote but can't get any audio. What happened?

First check all the wire connections at both ends of the remote. All five wires must be connected for proper operation. Also make sure you didn't "flip" the wiring at one end of the cable. It happens very frequently. Also note that once the front panel RMT button is pressed "in" both the PROGRAM SELECT and LEVEL functions only work at the remote. These two front panel controls are disabled when the CP 52/64 RMT switch is engaged. For testing purposes, push the RMT switch and make sure it's in the "out" position. Then, re-test all functions of the CP unit. If all works fine now then the problem lies in the remote or wiring to it.

I can't get either paging microphone to work. What am I doing wrong?

First check all the wire connections at both ends of the mic cable. Next be sure to set the PAGING INPUT MIC/LINE switches correctly. Facing the rear panel, MIC position is to the left. Once you have the setting correct turn up --- clockwise --- the PAGING TRIM control and see if you can light the PAGING OVERLOAD indicator. If it illuminates, you're getting hot enough audio into the paging preamplifier. Last practical field check is to be sure the front-panel PAGE ZONE ASSIGN switches are set correctly. If all this checks out, it's time to re-read the manual and follow the Recommended Calibration Procedure.

DA 216A / 216S:

Is it possible to get mic-level signals from the outputs?

Not without adding external pads. The DA 216a /S are distribution amplifiers supplying line-level audio so reducing the signal to mic-level requires an outboard attenuator of some type.

Where's unity gain on the DA 216a /S?

With "Line" & "0" dB of gain selected on the rear, the front panel Input gain is unity at full clockwise. There is 10 dB of gain between this point and the output, so with the inputs set in this manner, the output trims are unity at 12:00 noon.

EMPATH:

I noticed the EMPATH uses P & G faders, but the TTM 56 has your no-contact magnetic fader. Why isn't the 'mag fader used in the EMPATH? Can I put 'mag faders in my EMPATH?

The EMPATH is an all around touring, recording performance and club mixer. It covers the vast majority of today's DJ uses. Our TTM 56 is solely aimed at performance work (scratch and similar uses) which dictated the 'mag fader be utilized. Additionally when properly maintained, the P & G faders will last a very long time. Neither type of fader --- P & G nor 'mag fader --- can be retrofitted into any other mixers. They only work in the model we designed for them.

HC 6 / 6S:

When I use the direct inputs I lose the signal from my master, can I get both through the unit simultaneously at the same output?

No. You you need an external mixer to be able to hear both. Each input is either a direct headphone amp, or fed from the masters, but not a mix of the two signals. You can use any number of direct inputs and the remaining inputs will still receive signal from the master section.

How can I convert the DIRECT INPUTS to balanced mono?

A technician needs to remove to internal jumpers per input and solder two new jumpers into alternate locations silk-screened on the circuit board next to the DIRECT INPUT jacks. This change is fully documented in the Operator's Manual and requires familiarity with modern PCB servicing techniques. Current "S" version has plug-in jumpers providing end-user customization.

How loud is the HC 6 series?

It can be extremely loud, but it depends on your headphone impedance and sensitivity. For a list of the most popular headphones, and the SPL expected from each, See Understanding Headphone Power Requirements.

MA 3 and MA 4:

Can I feed all channels the same signal just by connecting to one of the channels?

Nope! You can use jumpers to connect all input channel connectors (plus and minus required, shield is discretionary).

Can I run the unit below 4 ohms load?

Well, probably. They will not be damaged but you will obtain much less power output. The MA 3 will current limit as necessary. Its fan must be set to high speed. The MA4 is a digital amplifier and handles lower impedance differntly than MA3. It too should work fine, but it is advised to always follow directions and load amplifiers accordingly.

I can't tell which terminals to connect to the amp on the 70.7 transformer (models TF 170 and TF 370).

Looking at the top of the transformer with all five terminals facing you and the three secondary terminals pointing NORTH, the upper left and lower right terminals are the MINUS (-) connections. The upper right and lower left are the PLUS (+) connections. The one remaining center terminal is the 25 Volt output connection --- applies to TF 170 and TF 370 only. Example: All four outermost terminals connected yields a typical 70.7 Volt output from an 8 ohm amplifier channel. Here are the TF 110, TF 170 and TF 370 technical details and mounting instructions.

My system seems a bit noisy running through the amp. Is there something wrong with the equipment?

Not likely. The most common misconception is that amplifiers must be turned up all the way to achieve maximum output. This is simply not the case. Most amplifiers will reach full output (and clip accordingly) with sensitivity controls set between 12 and 2 o'clock when fed a + 4 dBu signal. Try turning down your amp(s) and verifying the clipping point. This can make a drastic improvement in reduction of noise. See Setting Sound System Level Controls.

ME 15B / 15S / 30B / 30S:

What's the difference between the "B" version and "non-B" type?

The earlier units only had 1/4" inputs and outputs. Inputs are fully balanced, outputs are single-ended (some say "quasi-balanced") auto balancee/unbalanced. Ability to drive longer cables is less and high frequency rolloff can be a concern due to cable capacitance. Around 1994 we updated the design and changed to the "B" designation. These units have fully balanced inputs and outputs, both XLR and 1/4" TRS connections being utilized. Functionally the units are virtually identical. With the exception of much enhanced grounding, the older units possess almost the same sonic quality. The "S" versions have a new universal power supply, operating from 100-240 VAC (true for all Rane "S" models).

Can I use both the XLR and 1/4" outputs at the same time?

Yes. Both sets of output connections may be used simultaneously. However only one input may be used at a time. Also remember if you run unbalanced 1/4" with a balanced XLR you may have ground loop problems.

ME 60 / 60S:

If I use the RCA inputs with the XLR outputs does this make my system balanced? (ME60S does not have RCA connections)

Any unbalanced wiring in your system will unbalance the entire system, so you should try to run balanced everywhere possible. All subsequent wiring from the ME 60 downstream will be balanced in this scenario. We suggest reading Sound System Interconnection. If you feed a balanced input from an unbalanced output you can still retain the benefits of balanced wiring, but you have to modify your cables.

MLM 82 / 82A / 82S:

How I can assign the XLR microphone signals to left or right?

There is no provision to assign microphone signals on the original MLM82. Later versions "a" and "S" have A, A+B, B switches to determine where signals route.

MP 4:

I can't get my turntables or CD players to controls Scratch Live, What is wrong?

The MP4 does not support control signals, (i.e. control vinyl and control CDs). The only way to "scratch" with an MP4 is by using your computer's pointing device, (mouse, trackpad, etc.).

MP 2016 / XP 2016 / a /S:

I don't see any way to hear CUE and PROGRAM (MASTER) signals at the same time. Can this be done?

No the MP 2016 headphone and booth switching configurations do not provide simultaneous multiple signal monitoring. You can however send one signal to the BOOTH output and a different one to the HEADPHONE section. Whe the MP2016a was introduced, ability was added to monitor multiple CUE signals as well as blend CUE with house program signals, via the CUE / PGM MONITOR control.

Can I get a longer cable for the XP 2016 expander / equalizer unit? I want to mount them next to each other.

Yes. The longer version cable is 25" which provides enough length to mount the MP/XP combination side by side. It can be ordered directly from the Parts Department using part number 11537, (Standard 10" long cable is supplied with XP 2016. It's number is 10897.)

Will the XP2016 or XP2016a work with the current MP2016S?

Yes. All combinations MP/XP series mixers and expanders are fully compatible.

I can't get my BOOTH OUTPUT to play loud enough. Is something wrong?

Not likely. First easy way to test the mixer is flip the BOOTH CUE / MASTER toggle switch, up to the CUE position. If the audio from the BOOTH OUTPUT is now much louder then the mixer is fine and you need to run your levels higher. Make sure to set the INPUT GAIN controls so that the SIG / OL LEDs flash green. Also make sure that the MIX LEVEL controls are set to at least 3 o'clock. If the controls are set too low, then the BOOTH OUTPUT and MASTER OUTPUT signals will be weaker and the SIGNAL to NOISE ratio will suffer.

MP 24/x/z (all discontinued):

I need a new faceplate for my MP 24. How can I order one?

Front panels are no longer available for these discontinued models.

I can't get the AUX MIC to turn off all the way even with the control at zero.

This is not supposed to be a level for turning off the mic, but instead it is a TRIM for adjusting the gain of the input stage. The MIC ENGAGE switch is for turning the mics off.

Can I run the BALANCED and the UNBALANCED outputs to two different systems at the same time?

Yes. Just be aware that if you mix unbalanced with balanced you invite hum and buzz into your system.

Can I run an unbalanced line (like an RCA plug) into LINE 2?

Sure. Just get the appropriate adapter or cable to plug into the 1/4" TRS jacks and use the input like any other line input.

What is the EQ range switch on the rear of the mixer for?

This switch changes the amount of boost and cut the equalizer provides. In the out position, the equalizer controls allow plus or minus eight dB of boost and cut. When the switch is set to the in position, the range is plus or minus four dB of boost and cut. When a system is likely to distort, if the DJ "pumps up the bass," setting this switch to the "in" position (±4) can help to prevent overloading the system.

Is it possible to connect an XLR microphone to the AUX MIC input?

Yes. You will need an XLR to 1/4" balanced to unbalanced transformer. Cables are available with this device built-in.

Why can't I record my microphone when I'm making tapes, with my deck connected to the TAPE OUTS?

You need to change the settings for the jumpers J25 and J26. These send the microphone signal to the TAPE OUTS. (Older MP 24s [those with power switches] don't have these jumpers.)

What is the LOOP ENGAGE SWITCH for?

It turns on any processing connected to the SWITCHABLE LOOP. If nothing is connected to those jacks, the switch won't make any audible change.

All DJ Mixers:

When I use the 1/4" balanced outputs, no signal comes out, but the RCA jacks work fine. Why?

Typically this is caused by incorrect adapters being used. There is a 1/4" to RCA adapter available which looks balanced at the 1/4" end, but it's not. There is no such thing as a balanced 1/4" to RCA adapter. Those which have two insulators (look for two black stripes) and resemble a common stereo headphone plug are just that: a stereo plug. It's not balanced and won't work in the 1/4" output jacks. The correct adapter is an unbalanced (i.e. "mono") 1/4" plug to RCA jack. This is not the best way to hookup the mixer, but usually can be done without damage. If no adapter is being used, check the wiring at the other end. A balanced 1/4" cable should connect to an XLR plug as follows: Tip = Pin 2, Ring = Pin 3 and Sleeve = Pin 1. Connect all three wires and do not short any of them together at either end.

When I use a single cup headphone the sound is distorted. What's wrong?

Single cup headphone devices don't work with these mixers and may cause damage to the electronics in the unit.

What crossfaders can I install in my unit?

There are a few exceptions, but for the most part only one type of crossfader can be installed in any Rane mixer. Click here to see what the part numbers are: Crossfader Replacement Chart. Plug-in crossfader assemblies are only available for "x" and "z" version mixers. "x" series mixers require use of F45 or F60 spares, due to discontinuation of older parts. An adapter must be purchased to install the "F-type" spare. All others --- even those which have plug-in modules (MP 22 and MP 24) --- require soldering when replacing the crossfader. This is due to discontinuation of older parts.

Should I use a cleaner on the slide controls?

Absolutely! We use very high quality (high cost) slide pots and like a fine race car, maintenance is critical. If you keep the pot clean and lubricated it will last many years. If you neglect them then try to restore them with a generic cleaner you will just have to replace them. Don't just use any "contact cleaner", see our Detailed Slide Pot Care Procedure.

MRS 4:

Can I wire multiple MRS 4 to an RPM unit?

No. Only a single MRS 4 may be connected to the VIP terminals on an RPM device. However one MRS 4 may be connected to multiple RPM unit VIP terminals, providing memory recalls through different RPM products.

MS 1/a/b:

How can I rack mount the unit?

You may use any one rack space tray. This allows three MS 1a preamps to sit in a 19" space.

How do I wire the output for unbalanced use?

Since this unit uses a cross-coupled output, it is imperative that pin 3 be grounded to pin 1 and the audio positive connected to pin 2. It is also very important to make sure the unit is earth grounded using a separate wire connected to the chassis ground screw near the red power connector. See Sound System Interconnection for further details. Not having an earth ground connection to the chassis is the number one cause of failure.

RA 27 / RA 30 / RE 14 / RE 27 (all discontinued):

Can I extend the cable for the mic?

Yes, but it may cause more hum to be picked up and thereby causing a false reading @ 60 and 120 Hz.

How loud should my system be set when I use the analyzer?

Basically you want the PA set for a normal "playing" volume. Don't get ridiculously loud but have the system at a level loud enough to overcome any background noise.

I need a replacement mic for my unit. or My microphone stopped working can I get it repaired?

The microphone is not a serviceable item. Although delicate and very accurate it is quite affordable to replace in the event yours is broken or missing. Just contact the Parts Department and tell them you wish to order a MIC 2 Spare replacement analyzer microphone. An XLR to 1/4" tip-sleeve adapter is required to use the MIC 2 with all analyzers except RA 30. Rane does not supply this adapter.

Can I use a different microphone with the unit?

The MIC 1 is the only microphone we certify to operate correctly with the RA 27, RE 14 / 27 models. MIC 2 is for RA 30 but may be substituted for MIC 1 using correct adapter. Using any other device may damage the analyzer, measuring device or both. The one known measurement microphone witnessed compatible with the RA / RE series retails for over $ 500, thus it is wiser to purchase an original Rane microphone.

RaneGain:

Where do I connect the signal generator? My unit is not producing any sound, what's wrong?

The generator must be connected to a phantom power-equipped microhpone input. Without phantom power, the generator cannot produce signal. When you experience a "dead generator" symptom, check to be sure phantom power is switched on, or use an external phantom power adapter.

RaneWare

Whenever I open a window on a window the program crashes. What's happening?
Does RaneWare run under Windows Vista?

RaneWare is a 16-bit program written to run on Windows 95, 98SE and earlier OS's like Windows 3.1, 3.11, NT 3.5x and 4.x. Windows 2000 will not support RaneWare. Windows ME is reported to work, but is not officially supported. Windows XP can work, but only with the use of a specific third-party USB to serial adapter, manufactured by Keyspan, (see it here: http://www.kespan.com/products/usa19hs/). Windows Vista has not been tested and no plans exist to recompile RaneWare for compatibility with it. Officially we support only the Windows 98SE and earlier operating systems. The only solution is to run the earlier version: Windows 95 or 98SE. Other OS's might work but we can't guarantee or support all the variables.

Windows NT 4.0 seems fine, but you cannot print consistently with version 2.3. RaneWare version 2.2 does seem to print correctly under NT 4.0.

RaneWare does not work in any modes under Windows 2000. It "crashes and burns" if not immediately after startup, then soon after. WOW32.DLL is the most common problem witnessed under Windows 2000.

Under Windows ME, it seems "OK" in offline mode and fairly inconsistent in online (i.e. hardware connected) mode.

Under Windows XP, offline mode seems "OK" but online mode is anybody's guess. It varies wildly depending on if it's a desktop versus laptop machine and also what type of ports are on the unit. Machines sporting USB ports running XP are far more likely to experience issues when polling for our hardware.

How many conductors are required to interconnect units to the COM port on the computer?

The RS 232 cable for the unit uses two conductors and a shield. Pins two and three are the data with pin five being the shield.

I lost the password for the RaneWare. Now what do I do?

There is a file that contains the information which will have to be deleted. Once it's gone all the Site Control Panel names will be lost. This file name can be obtained by contacting us by fax, phone or email. [We won't post the name here just in case someone has a warped sense of humor.]

I'm running RaneWare in Windows 95/98 and got stuck in the Site Control Panel. How do I get out of it?

Right mouse click on the Title Bar (the top of the window where it says Site Control Panel) and select Device Edit. You will then need to enter the password, (stock is "please".) In case your mouse isn't working you can get to the Device Edit option by pressing Alt. and the Spacebar together. This will give the drop-down options of: Device Edit or Exit.

RS 1/RS 2 (RS 2 for CP 62 only):

Why do you use "wall warts?"

We don't. The common term wall wart refers to power supplies that include the AC plug prongs in the housing with the transformer. This causes the unit to be take up unnecessary space on an outlet strip and prevents secure mounting in a rack. Our remote power supply has a 6' cord for each high and low voltage connection in addition to mounting tabs built into the case. Other benefits for using external transformer power supplies are numerous. Some important reasons are: UL and other agency certification on one power supply keeps prices down. External transformers result in lower hum and noise figures. Service replacement and multiple unit powering is a much simpler issue to deal with. Having an external supply with a thermal circuit breaker (Rane does not use glass fuses) allows the supply to shut off during a fault and come back on when the problem is solved thereby avoiding the "blown fuse" symptom. See External Power Supplies..

My unit says RS 2 on the rear but it came with an RS 1. Will the RS 1 work with the unit?

Absolutely! All Rane products, with the exception of the CP 62, will operate perfectly on the RS 1. This includes older units that originally shipped with an RS 2. The discontinued CP 62 is the only Rane product which required the RS 2.

RS 3:

My RS 3 has quit working, do you repair them? Can I buy another one?

RS 3 power supplies are non-serviceable units (i.e. disoposable). Unfortunately it is no longer available as a spare part. Closest approximation we have found may be seen here: JameCo PN 211191.

SAC 22 / SAC 23:

How are these units different from the AC 22 and AC 23?

The SAC series crossovers are stereo units. One control affects both channels left and right. The AC series units are dual mono. This means channel one can be set differently from channel two. Additionally, the AC series units provide driver alignment delay controls and optional CD horn compensation.

Why do these crossovers only have XLR connectors?

After conducting extensive research, we found that since space forced us to make a choice between XLR and 1/4" connectors, our customers preferred a locking, balanced professional audio standard connector.

Can I use just the Highs and Lows to run the SAC 23 in 2-way mode?

Yes you can, if both frequency selectors are set at the same crossover point. The high frequency output will be 6 dB lower in level than the low frequency output. It is much better to use the SAC 22 or AC 22B for a 2-way application.

SM 26 /26B / 26S:

Are the inputs and outputs balanced?

On both the SM 26, 26B and the current 26S all inputs are fully balanced. The first model SM 26 has only balanced inputs, the outputs are single-ended (some say quasi-balanced) with an ungrounded "floating" sleeve connection. For typical applications this is not a limitation, just a consideration for wiring and RF rejection. The SM 26B has been in continuous production since 1994, replacing the SM 26. The "S" version has a new internal universal power supply, operating from 100-240 VAC (true for all Rane "S" models).

When I split and mix simultaneously there is phase cancellation at the MIX OUTPUTS, what's wrong?

Due to the summing node being inverting there is a combination of hookups which will produce phase cancellation due to signal inversion. Remove the internal jumpers (six total) to rectify this situation. Only SM 26B units have these jumpers, they were not part of the SM 26 design. Sorry to those using older pieces for this limitation.

SM 82 / 82S:

Are the inputs balanced?

No. This piece is primarily aimed at the keyboard and similar sources. If you need fully balanced inputs use the SM 26S or the MLM 82S. However, the SM 82 outputs are balanced.

Can I modify the unit's aux send to be pre fade?

This unit is really packed tightly and just doesn't allow room for this. The performance would be seriously compromised, and because it's a double sided board a modification would take four or five hours if you really knew your way around inside the unit.

SR 2 / 3 / 4:

One or more remotes has a flashing red LED and won't control the RPM unit. What's wrong?

Make sure that every remote is set to its own address, and check to be sure the A and B data lines are not reversed. Equally important to correct wiring is using pairs of twisted conductors (i.e. A = blue w/ white, B = blue, V+ = green w/ white, V- = green etc.). Don't mix wires from different pairs. Also do not "double up" extra pairs on the A and B data lines, as the extra capacitance can affect communication.

I have remotes connected to an RPM xx and can upload / download to / from the SR 3s but they will not "talk to" (control) the Drag Net unit. Is there a setup issue or am I missing something?

The RPM xx polls (searches) for Smart Remotes when it is first turned on. It's sort of a roll call to see which addresses are being used. Any devices connected correctly are seen and commands from them recognized. However any remotes not connected and powered up at the moment power is supplied to the RPM xx will be ignored. The first resolve is always to cycle the power at the RPM xx (unplug it, and plug it back in). Typically this cures the "my remotes don't work" symptom. For the computer types out there, this operation is very much the same as polling for SCSI hard drives at boot-up. Only active devices found during polling will be useable by the computer.

I have remotes connected to an RPM 88, but some are not working and appear completely dark

The RPM 88 can only power three SR 3 or six SR 4 remotes. If more remotes will be used on an RPM 88, then an external power supply must be utilized (do not connect any wires to the V+ and V- terminals of the RPM 88 in this instance). Refer to the zipped Excel file: SR Cable Length Calculator Spreadsheet for specific details on wiring, power consumption and other details.

TTM 56:

Will the no-contact magnetic fader work in any other mixers?

No. This very complicated precision device is engineered to work only within the TTM 56 architecture. It is not compatible with any other units.

How can I order a spare fader for my TTM 56?

We do not sell the complete fader for this mixer. It is not necessary to replace the entire fader. As a service spare part, the carrier assembly (part number 13188) is available. it consists of the Delrin housing, with magnet installed and pre-aligned torsion spring. This three-piece entity is all that will be necessary for field repairs. Any work beyond replacement of the carrier needs to be done here at the Rane factory. TTM 56 mixers are Factory Service Only so parts and schematics are not available outside the factory.

I've seen P & G faders available for the TTM 56 over the internet. Why doesn't Rane list them as an option?

Rane does not offer Penny and Giles faders for the TTM 56 because they will NOT work in the mixer. The circuitry which reads the no-contact magnetic faders is not calibrated and cannot be reset to operate with the P & G faders. Plugging in one of these devices will cause very abnormal responses from the mixer and should be avoided. Do not be fooled by the misinformation listed by some vendors on the internet. These are the facts from the company that designed the mixer.

The fader doesn't feel right. It seems to stick or bounce back a little. What can I do? Can I take out the spring or adjust it?

Oiling is the best way to address a fader drag problem. Remove the face plate and apply lubricant to the support rod near the spring. If the rod is dirty, carefully clean with a lint free cloth before lubricating. A great way to polish the rods and remove accumulated contaminants is to tear off a strip of newspaper wide enough to fit around the exposed length of rod, and wrap it around the shaft. Then you can pull strip back and forth to buff the rod (think of it like polishing a shoe, but in reverse). Once this is done, the dirt will have been wiped away and a clean stainless shaft is ready for oiling. We recommend true silicone lubricant, commonly available at hardware stores and automotive parts retailers. Sewing machine oil is probably okay. Bending the spring may permanently damage it, and will void your warranty. When performing any maintenance, use common sense and proceed very carefully.

For those who wish to obtain almost zero drag on the fader, gently push the spring downwards towards the circuit board, and rotate out from under the rod, then release. The spring will be above the rod and not making contact. This setting allows the fader to move more easily. This can make controlled fading difficult, because the fader moves freely when released. You will not hurt the fader operating it this way. Small mechanical parts are easily damaged, so use care when lubricating or moving the spring.

What are the differences between the TTM 56 and the TTM 56i?

There is no such model as the TTM 56i. We have only made the TTM 56. It has two versions earlier and later, distinguished by the knobs and front panel graphics. The latter has taller rubber knobs and rounded piping highlights for the graphics.

I cannot figure out how to make the effects work. What am I doing wrong?

The TTM 56 does not have any built-in effects processor. You must connect a separate outboard unit.

I cleaned / lubricated the fader and it feels better, but now it won't turn off all the way (bleeds) when I have the contour set to fastest cutoff. What happened?

The hall sensor got pushed (bent) and is now too far from the magnet. Look for a small black plastic device --- about 1/8" square --- just below the rods at each end of the fader, mounted on the circuit board. It needs to be perpendicular to the PCB. If the sensor has been "bumped" during cleaning / lubrication, then it will not be close enough for the magnet to "turn off" the fader completely, resulting in bleed. Fix the problem by gently bending the sensor towards the middle of the fader, closer to the magnet. It doesn't take much movement to get it correct, so proceed carefully. A paper clip used gently works well, as will a very small screwdriver. If you break the sensor off, you'll need to get another fader so be extra cautious.

VR 1:

Is it possible to use a single VR 1 to control volume remotely and still use the front panel program selector on CP 52 / CP 64 series units??

No. Once the RMT switch in engaged on a CP 52 / CP 64 series, it disables Program Selector switch. Using a VR 1 with CP 52 / CP 64 series models yields only Line 1 input being available for that zone. Automatic switching to Priority / Line 4 program input is unaffected by this combination.

ZR 1:

Is it possible to use a single ZR 1 to control both zone selections on a CP 64 series unit?

Wiring D0 and D1 together on a CP 64 / CP 64S will cause one remote selector to affect program choices in BOTH zones. It is not recommended to wire Vc together for single remote volume control, which also negates having two discrete zones in the first place. Use a ZR 1 for level control in one zone and a VR 1 for level control in other. ZR 1 selector then affects source choie in BOTH zones.

Detailed Slide Pot Care Procedure

Although Rane does not expect slide pots to need routine cleaning, there are certain harsh environments where this may prove beneficial.

Supplies
The only product authorized by Rane for use in our potentiometers is CAIG Laboratories DeoxIT Faderlube.

Procedure:
1. Make sure the equipment is turned off and preferably unplugged.
2. Position the fader to be cleaned in such a way that it is easily accessible.*
3. Cover and protect any finished surface which may be affected by over-spray.
4. Using the spray tube, apply three short bursts of DeoxIT Faderlube 5% carefully into the control. This is CAIG part number F5S-H6 in a 5 ounce aerosol. If done regularly, in many situations this is sufficient maintenance and no further lubrication is necessary.
5. Operate the control through its entire travel to distribute the cleaner.
6. Collect any excess cleaner and prevent it from flowing uncontrolled.
7. Apply three more short bursts of DeoxIT Faderlube 100% for additional lubrication. This is CAIG part number F100S-L2 in a 2 ounce aerosol.
8. Again, work the lubricant into the device by operating the control repeatedly.
* The monorail crossfader used in all "z" mixers the TTM 52 and TTM 54 must be removed from the unit to apply cleaner-lubricant.
At this point the control should be operational. If fader performance is questionable then replacement of the pot is the only sure remedy.

Maintenance Intervals:
Products which are used in harsh environments should be cleaned and lubricated regularly. Interval to be determined by the user. Slide controls that are scratchy intermittent or mechanically binding should be cleaned immediately to prevent further wear to the component.
