DATA SHEET
MLM 82a
MIC/LINE MIXER
General Description
The Rane MLM 82a 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 MLM 82a 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.

Applications
With new features like MIC/LINE A/A+B/B ASSIGN
switches, independent STEREO LINE INPUT MONO
switches and additional line gain, the MLM 82a has far
greater flexibility than its predecessor. The MLM 82a is now
one of the most versatile mixers in its class. It is ideal for
installations requiring ease of use, compact size, low cost,
high performance and security. Applications include, but are
not limited too, hotels, churches, conference rooms, schools
and rental sound systems. The studio-grade specifications of
the MLM 82a allow many other applications such as submixing, recording and post-production.
The addition of MIC/LINE A/A+B/B ASSIGN switches
and independent MONO switches for each of the STEREO
LINE inputs make the MLM 82a a true, dual zone capable
mixer, i.e., the outputs may be thought of as two independent
zones or a single stereo zone.

MIC/LINE MIXER
Rear Panel
Architectural Specifications
The mixer shall have four studio-grade mono mic/line
inputs each with XLR input jack, 15 volt phantom power, line
pad, A/A+B/B mix assign switch, level control and signal/
overload indicator. A single switch shall make phantom
power available to all four microphone inputs. Phantom
power shall be removed automatically from any mic/line
input set for line input. For ease of use, mic/line preamplifiers
shall use a single control for input gain trim and mix level.
The mixer shall feature four stereo line inputs each with
¼" TRS input jack, level control and pre-level control mono
switch. The inputs shall provide for dual mono operation with
four mono signals available for the A mix and four mono
inputs available for the B mix.
A and B mix outputs shall feature overload indicators,
independent A/B level controls, internally selected 40 dB pad
for microphone level output and XLR output jacks.
Security features shall include placement of the phantom
power and line switches on the rear panel, recessed A/A+B/B
mix assign switches, internally located pad switch for
selecting line or microphone output level and recessed stereo
line input mono switches with position indicators. In addition,
each of the front panel level control knobs may be removed
and replaced with a security plug. Four security plugs shall be
provided for this purpose.
The unit shall be exempt from agency safety requirements
and powered from a UL listed / CSA certified (120 VAC), or
CE approved (230 VAC) remote power supply. The unit shall
be constructed of cold-rolled steel and mount into a standard
19" 1U EIA rack.
The unit shall be a Rane MLM 82a Mic/Line Mixer.
