The evolution of the entertainment industry has necessitated the creation of an outboard mic/line device to compliment existing mixing consoles. Whether you’re recording, mobile mixing, or broadcasting, there are occasional needs to expand your existing arrangement. Frustrations abounded when it came to adding mics for interviews, karaoke, and live performances because it was cost prohibitive. Now it’s quite inexpensive to enhance your existing gear and expand the number of live mics for any gig. The MLM 42S is unique. These mic preamps give you the studio-grade quality you need.
Applications are everywhere. The MLM 42S is designed to fit into a variety of situations where cost is an issue and Rane quality is a must:
Each input includes all the features you need:
Rane’s patented tone control technology produces steeper slopes than normal, thus allowing boost/cut of high and low frequencies without disturbing the critical midband frequencies. The MLM 42S features full-cut Tone Controls, allowing much greater contouring than possible with regular controls.
