MLM 82a CONNECTION
When connecting the MLM 82a to other components in
your system for the first time, leave the power supply for last.
is gives you a chance to make mistakes and correct them with-
out damage to your fragile speakers, ears and nerves.
MIC/LINE INPUTS 1-4
e four XLR jacks provided on the MLM 82a are balanced
MIC/LINE inputs. ey will also accept unbalanced connec-
tors. Use only shielded cable for inputs. For best noise rejection
use two-conductor-plus-shielded wire, even for unbalanced
operation. Connect the shield at both ends to help insure proper
grounding. See the Sound System Interconnection RaneNote
included with this manual for all cable adaptations. Rane follows
the AES recommended practice of pin 2 positive, pin 3 negative,
and pin 1 to shield. Switch any input connected to a microphone
to the MIC position (out) using the associated switches on the
rear panel. When connecting line level signals, switch the input
to the LINE position (in). A single phantom power switch is
provided for the four MIC inputs. If LINE is selected, Phantom
Power is disabled for that input.
QUICK START
is section is provided as a convenience for those in a rush. If you are experienced with this unit or other Rane products, these
few words will refresh your memory.
INPUTS 1 through 4 may be microphone or line level. e choice between the two is made by setting the LINE push buttons
on the REAR of the unit next to the MIC/LINE INPUT JACKS. Each microphone input may be assigned to A, B or A+B outputs
using the front panel ASSIGN switches.
INPUTS 5 through 8 are stereo line inputs which may be set to mono using the recessed MONO switches located on the front
panel.
Internal switches allow setting output signal levels for MIC or LINE. e factory default setting is LINE. If the MLM 82a is
connected directly to a power amplifier, equalizer or recorder input, choose LINE level. If the MLM 82a is connected to a micro-
phone jack of an existing sound system, choose MIC level.
Once Inputs, Outputs, and power are properly connected, with the OUTPUT LEVELS counterclockwise (off ), set the Input
LEVELS as high as possible without causing the SIG/OL indicators to blink red except during extreme signal peaks. Now slowly
raise the OUTPUT LEVELS as desired.
Never connect anything except an approved Rane power supply to the red thing that looks like a telephone jack on the rear
of the MLM 82a. is is an AC input and requires special attention if you do not have a power supply exactly like the one that was
originally packed with your unit. See the full explanation of the power supply requirements on page Manual-3.
STEREO LINE INPUTS 5-8
e ¼" connectors are line-level balanced/unbalanced
Inputs. If the MLM 82a is to be used with unbalanced sources,
consult the Sound System Interconnection RaneNote included
with this manual for proper wiring. Stereo Inputs use both A
and B jacks at each INPUT. INPUTS 5 through 8 also serve as
mono Inputs when the front panel MONO switch is engaged.
OUTPUTS
e MLM 82a’s OUTPUTS are balanced. e same wiring
conventions as the XLR Inputs apply. e type of device follow-
ing the MLM 82a must be considered when setting the internal
Output Level switch. Choose between LINE (0 dB) or MIC
(-40 dB) output, the factory setting is LINE. If the MLM 82a
is connected directly to a power amplifier input, choose LINE
level. If the MLM
82a is connected to a
microphone jack on an
existing sound system,
choose MIC level. For
unbalanced OUTPUT
connections do not
tie pin 3 (i.e. “–”) to
ground.
