MLM 103
MIC/LINE MIXER
OPERATORS MANUAL
WEAR PARTS: is product contains no wear parts.
QUICK START
If you don't get any further, at least read this section to get the
best gain structure out of the MLM 103.
INPUTS 1 through 6may be microphone or line level. e
choice between the two is made by setting the Input’s LINE
push-button on the rear panel.
Push the PHANTOM POWER button (when needed) for
each pair of Inputs.
Using a screwdriver, adjust the TRIM for each Input so that
the front panel OL LED illuminates only occasionally during
extreme peaks. e three-band Equalizer settings will influence
this, so keep an eye on the OL when making EQ adjustments.
Now adjust the LEVEL for each Input.
Assign each Input to the desired Output by pushing any
combination of the A, B, or AUX ASSIGN buttons.

INPUTS 7/8 and 9/10 are stereo line level Inputs.
Assign each stereo input to the desired output as follows:
When the ASSIGN button is engaged and the MONO but-
ton is not engaged, INPUT 7 (or 9) is routed to the AOutput,
while INPUT 8 (or 10) is routed to the B Output.
When the both the ASSIGN and MONO buttons are en-
gaged, both Inputs of 7/8 (or 9/10) will route to both the Aand
B Output.
e AUX ASSIGN button is always a mono mix of the stereo
channel.

Manual-2
FRONT PANEL DESCRIPTION
1Mic/Line Input LEVEL controls 1-6 determine the amount of signal to be delivered to the assigned Outputs. e Overload
light monitors the signal level before and after the Equalizer. If this illuminates steadily, turn down the LEVEL or EQ controls to
prevent distortion.
2Mic/Line Output ASSIGN buttons. When the A button is engaged, the Mic/Line Input’s audio is routed to Output A.
When the B button is engaged, the Input’s audio is routed to Output B. When the AUX button is engaged, the Input’s audio is
routed to the Aux Output. Any (or all) of the ASSIGN buttons can be engaged simultaneously.
3Equalizer controls are used to contour the frequency response of the desired Input. LOW affects frequencies below 300 Hz,
MID affects 300 Hz to 3.3 kHz, and HIGH affects frequencies above 3.3 kHz. e Equalizer sounds best and potential overload
is avoided when at least one of the three bands is set to cut (below 0).
4Stereo Line INPUT LEVEL controls 7/8 and 9/10 determine the amount of stereo or mono line signal to be delivered to the
assigned Outputs. e Stereo Line Overload light monitors the signal levels after the Equalizer and after the line gain stage. If this
illuminates steadily, turn down the LEVEL or EQ controls to prevent distortion.
5Stereo Line Output ASSIGN buttons. When the A/B assign button is engaged and the MONO button is not engaged, Input 7
(or 9) is routed to the A Output, while Input 8 (or 10) is routed to the B Output. When both the A/B ASSIGN and MONO but-
tons are engaged, both Inputs of 7 and 8 (or 9 and 10) will be routed to both the A and B Output. e AUX ASSIGN button is a
mono mix of the stereo Inputs.
6A, B and AUX OUTPUT LEVEL controls set the Output Level for A, B and AUX Outputs. e Output Meters indicate the
overall levels of Output A, Output B and the AUX Output. e Meters are “peak hold”.
7POWER indicator lights whenever adequate power is applied to the unit.

REAR PANEL DESCRIPTION
1MIC/LINE INPUT TRIM controls 1-6 adjust the input gain of the Mic/Line Inputs. e gain range for Mic level is 12 to 60
dB. e gain range for Line level is -4 to 12 dB.
2LINE/MIC INPUT buttons 1-6 switch the sensitivity and input impedance for either a microphone or line input. Mic level is
selected when the button is in the “out” position. Line level is selected when the button is in the “in” position.
3MIC/LINE INPUT connectors 1-6 are balanced Euroblocks that connect either microphone or line signals.
4PHANTOM POWER button applies 12 volt phantom power to each pair of Mic/Line Inputs, only when the LINE/MIC IN-
PUT button (2) is set to the MIC “out” position.
5STEREO LINE INPUTS 7/8 and 9/10 are pairs of balanced Euroblock connectors, accommodating stereo or mono line level
signals.
6PRE/post MIX LEVEL DIRECT OUTPUT buttons. When this switch is in the “in” position, the Direct Output signal is not
affected by the Input’s Level control. When this switch is in the “out” position, the Direct Output signal is affected by the Input’s
Level control.
7DIRECT OUTPUTS are balanced Euroblocks that directly connect each Mic/Line Input signal to other audio devices as
needed. ese Direct Outputs are post-Equalizer.
8A, B and AUX OUTPUT connectors. One 6-post balanced Euroblock connects the A mix and the B mix to other audio devices
as needed. e other 3-post balanced Euroblock connects the AUX mix to other audio devices as needed.
9e IEC appliance input jack uses a C5 cord, connected to AC mains using a line cord appropriate for your area. e high effi-
ciency switching power supply used in the MLM 103 operates at voltages from 100 VAC to 240 VAC, 50 or 60 Hz. To prevent ac-
cidental shutoff during the president’s speech, there is no front panel power switch. When applying power to the system, remember
to turn power amplifiers on last.

OPERATION
MONO MICROPHONE/LINE LEVEL INPUTS 1-6
e rear-panel MIC/LINE INPUT TRIM adjusts the input
gain before the front panel LEVEL controls. When an Input’s
LINE/MIC button is in the “out” position (Mic Level), the gain
range is 12 to 60 dB. When an Input’s LINE/MIC button is in
the “in” position (Line Level), the gain range is -4 to 12 dB.
First, input some “loud” source material (like a pop metal
or disco CD, give a kid a mic, etc). en, using a screwdriver,
adjust the TRIM for each Input so that the front panel OL LED
illuminates only occasionally during extreme peaks. e 3-band
Equalizer settings will influence this, so keep on eye on the OL
when making EQ adjustments.
Push the PHANTOM POWER button (when needed) for
each pair of Inputs. If the LINE/MIC button is engaged (Line
Level), Phantom Power is automatically defeated for that Input.
e PHANTOM POWER button activates 12 volts which is
sufficient power for all but the most esoteric condenser mics. If
in doubt, check the manufacturer’s microphone specs.
Assign each Input to the desired Output by pushing any
combination of the A, B or AUX ASSIGN buttons.
e LEVEL of each Input can now be adjusted as needed
without danger of blowing your speakers, or scaring the neigh-
bors, whichever you deem worse.
STEREO LINE LEVEL INPUTS 7/8 and 9/10
When a stereo source (CD, DVD, Satellite radio, etc.) is con-
nected to Inputs 7/8 (or 9/10), the routing is as follows:
When the ASSIGN button is engaged and the MONO but-
ton is not engaged, INPUT 7 (or 9) is routed to the A Output,
while INPUT 8 (or 10) is routed to the B Output.
When both the ASSIGN and MONO buttons are engaged, a
mono mix of INPUTs 7/8 (or 9/10) will be routed to both the A
and B Outputs.
e AUX ASSIGN button is always a mono mix of the stereo
channel.
OUTPUT LEVELS
After all of the Mic/Line and Stereo Input Levels have been
adjusted and routed, adjust the OUTPUT faders so the Meters
peak average around 0 to +2.
SECURITY COVER
e MLM 103 comes with an installed security cover for the
EQ and ASSIGN switches only, leaving the LEVEL controls and
metering exposed for regular operation. is feature is valuable
when you want to protect those painstaking settings from casual
operators.
e cover is removed and replaced by two screws. If the se-
curity cover will not be used, remove the chrome standoffs from
the front panel and replace with the black screws in these same
locations.
CONNECTION
INPUTS
e MLM 103 has ten balanced Euroblock Inputs. Use only
shielded cable, #12 to #24 AWG. For best noise rejection use
two-conductor-plus-shielded wire, even for unbalanced opera-
tion. Connect the non-inverting (positive) audio lines to the “+”
terminals, and the inverting (negative) lines to the “–” terminals.
Connect the shields to the “ground” terminals.
For those installations where the MLM 103’s internal shield-
to-chassis connection causes interference, connect the shields
directly to chassis PEM nuts directly above each pair of Eurob-
lock connectors. Be sure to bite through the paint with the star
washer and keep the shields wrapped around the audio conduc-
tors as much as possible. For the “theoretical” best ElectroMag-
netic Interference (EMI) immunity, connect the shields at both
ends of the cables. (For more information on connections, see
the RaneNote, “Sound System Interconnection” later in this
manual or on Rane’s website.)
MONO INPUTS 1-6 can accept either mic or line level
sources. When connecting line level signals, push the rear panel
button in for LINE. For mic signals, be sure the button is in the
MIC (out) position.
STEREO INPUTS 7/8 and 9/10 accept line level stereo and
mono sources.
OUTPUTS
e MLM 103’s OUTPUTS (and DIRECT OUTPUTS) are
balanced. e same wiring conventions as the Euroblock Inputs
apply.
