MLM82S Stereo Mixer


The Rane MLM82S features four balanced, studio grade, mono Mic/Line inputs with XLR jacks and 15 VDC phantom power. Each of the four Mic/Line inputs may be assigned to A, A+B or B Outputs. Independent Level/Gain Trim controls and Signal/Overload indicators are provided for each Mic/Line Input. The Phantom Power switch and the Mic/Line switches are located on the rear panel. Phantom power is removed from any Input set for Line operation.

The MLM82S also features four stereo line level inputs with 12 dB of line gain. Each Stereo Line input features a recessed Mono switch with indicator and Level control. These inputs may also be used with four Mono A inputs and four Mono B inputs. You get the picture...this mixer is very versatile.


A and B Output Level controls set the master mix level independently for A and B Outputs. The mix amplifiers feature independent overload indicators. To correct any overload condition, the entire mix can be reduced and/or individual Input Levels adjusted. A and B mix Outputs each have an internal switch for padding the output signal to Mic level. The factory default is Line level.

Application: Mics and Keyboards

MLM82S Music Application

The MLM82S can be a compact mixer for 4 mics and 4 stereo electronic instruments right to an amplifier, or it can be a local sub-mixer for a larger system like a theater. The studio-grade specifications of the MLM82S are clean and ideal for sub-mixing, recording and post-production. The XLR outputs can be switched to Mic level with internal switches.

Application: Conference Room

MLM82S Conference Application

The Mic/Line Assign switches and independent Mono switches for each of the Stereo Line Inputs make the MLM82S a true, dual zone capable mixer, i.e., the Outputs may be thought of as two independent zones or a single stereo zone. In this example, when a mic is switched to "B" it is only sent to the output audio feed in a teleconference. The line sources, with Mono switches on, are heard in both locations.

This system can also serve as a 2-room combine by replacing the Teleconference output with a second powered speaker or ceiling array for the other end of a room. Each mic can be switched to be heard in Room A, B or both.
