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 MLM82S is con­nected directly to a power amplier, equalizer or recorder input, choose LINE level. If the MLM82S is connected to a microphone jack of an existing sound system, choose MIC level.
Once Inputs, Outputs, and power are properly connected, with the OUTPUT LEVELS counterclockwise (o ), 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.
MLM82S CONNECTION
When connecting the MLM82S to other components in your system for the rst time, leave the power cord for last. is gives you a chance to make mistakes and correct them without dam­age to your fragile speakers, ears and nerves.
MIC/LINE INPUTS 1-4
e four XLR jacks provided on the MLM82S are balanced MIC/LINE inputs. ey will also accept unbalanced connec­tors. 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.
STEREO LINE INPUTS 5-8
e ¼" connectors are line-level balanced/unbalanced Inputs. If the MLM82S 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 MLM82S’s OUTPUTS are balanced. e same wiring conventions as the XLR Inputs apply. e type of device follow­ing the MLM82S 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 MLM82S is con­nected directly to a power amplier input, choose LINE level. If the MLM82S 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.
WEAR PARTS: is product contains no wear parts.

1 SIGnal present/OverLoad LED. is bi-color LED lights green for a -30 dBu signal, and turns red when the Input is within 3
dB of clipping.
2 MONO MIC/LINE INPUT LEVEL controls 1-4 determine the MIC/LINE preamp gain and mix level to be assigned to the A,
A+B, B Outputs.
3 ASSIGN switches determine between the A, A+B or B Outputs for each MIC/LINE input.
4 STEREO LINE INPUT LEVEL controls 5-8 determine the amount of stereo or mono line Input routed to the Outputs.
5 MONO switch mixes the A and B sides of each STEREO LINE input together. When active, the associated LED lights, and the A
and B Inputs for that channel have exactly the same level.
6 OUTPUT OverLoad LED illuminates within 3 dB of an approaching overload condition. To avoid this, the associated OUT-
PUT LEVEL control may be decreased, or the problem-causing individual Input Level may be lowered.
7 A and B OUTPUT LEVEL controls set the Output Level for A and B outputs.
8 POWER LED is lit whenever adequate power is applied to the unit.

1 MIC/LINE INPUTS 1 through 4. ese XLRs connect either balanced Microphone or Line signals, depending on the LINE
switch setting (see 3). Rane adheres to the international and U.S. standard for balanced pin congurations: Pin 1 is chassis ground (neutral), pin 2 is positive (+), and pin 3 is negative (–).
2 PHANTOM POWER switch applies 15 V Phantom Power to any Inputs 1-4 that are set for MIC Input.
3 LINE Input selectors switch the sensitivity and input impedance for either a microphone or line level input. If LINE is chosen,
Phantom Power is deactivated for that Input.
4 ¼" LINE INPUTS. ese stereo pairs of balanced inputs accommodate stereo line-level signals. ese TRS (Tip-Ring-Sleeve) ¼"
jacks handle either balanced or unbalanced signals. In most cases an unbalanced signal may use a mono ¼" plug (Tip-Sleeve). See the Sound System Interconnection RaneNote included with this manual for proper connection.
5 A and B OUTPUT jacks. ese balanced XLR’s provide the A and B mixed output. INTERNAL OUTPUT LEVEL switches
allow setting the output level for MIC or LINE level. Pin connections are the same as above in 1.
6 Power connector: e internal universal switching power supply operates on any AC mains 100 to 240 VAC, 50 or 60 Hz (most
places in the world). All that is required when traveling is the appropriate IEC line cord.

OPERATING INSTRUCTIONS
MONO MICROPHONE/LINE LEVEL INPUTS 1-4
e microphone preamps in the MLM82S have a combination gain trim and Level control. e LEVEL control adjusts both the input dynamic range and mix level. ere is no need for the typical independent gain trim control found on most mixers. e PHANTOM POWER switch activates 15 volt Phantom Power for all Inputs selected for microphone use. With LINE selected, Phantom Power is defeated only in that Input. 15 volts is su­cient power for all but the most esoteric condenser microphones. If in doubt, check the manufacturer’s microphone specs.
SIGNAL PRESENT/OVERLOAD INDICATORS
e MLM82S has four bi-color indicators for Signal Present/ Overload (green/red). Green indication occurs when there is a signal present above -30 dBu. is lamp should be glowing green when signal is present. If this lamp is o, check these possibili­ties: A. e Input may not be connected. B. ere is little or no signal present at the moment. C. ere is a Mic connected to a channel switched to LINE. D. e Mic needs Phantom Power (See Rear Panel, 2). E. e LEVEL control needs to be increased (clockwise). F. e cable is not wired properly (See the Sound System Inter-
connection RaneNote).
STEREO LINE LEVEL INPUTS 5-8
e STEREO LINE INPUT LEVEL controls adjust both A and B Inputs equally. Use the OUTPUT LEVEL controls together for overall output adjustment, or separately to control balance.
A single mono input may be used for the A and/or B inputs. Any mono source connected to A will go to the A output. Any mono source connected to the B input will go to the B output. If you wish one or two mono sources to go to both A and B outputs, press the MONO switch. If you wish to mono a single stereo source and have it present in A and B outputs, press the mono switch. STEREO LINE INPUTS 5-8 may each be inde­pendently set for mono operation.
HOLE PLUGS
To protect the setting of any rotary control, remove the knob by simply pulling it o, and snap in one of the hole plugs included with your unit.
To protect the entire front panel, use a Rane SC 1.7 Security Cover.
A red glowing LED indicates that the levels are so high that
distortion due to clipping is occurring or imminent. Check these conditions: A. e LEVEL control may be turned too high. B. e Output of the preceding device may need to be reduced. C. e Input may be switched to MIC with a line-level source.
Switch the Input to LINE.
STEREO LINE INPUTS 5 through 8 do not have overload indicators. Because 12 dB of gain is added after the STEREO LINE INPUT LEVEL controls, it is possible to overload a line input without an overload indication. e A and B OUTPUT OL indicators can overload from the Line Inputs if the OUT­PUT LEVEL controls are set to 10. Although a single Input may be at unity gain, multiple active Inputs mixed together can cause an overload. If the OL indicators illuminate, just turn down the OUTPUT LEVELS until the overload stops—mix ratios will not change.
