MLM 103 OPERATION
MONO MICROPHONE/LINE LEVEL INPUTS 1-6
The rear-panel MIC/LINE INPUT TRIM adjusts the input
gain of these Inputs, before the front panel LEVEL controls.
When an Input’s LINE/mic button is in the “out” position
(Mic Level), the gain range is 15 to 60 dB. When an Input’s
LINE/mic button is in the “in” position (Line Level), the gain
range is 0 to 12 dB.
First, input some “loud” source material (like a pop metal
or disco CD, give a kid a mic, etc.) Then, using a screwdriver,
adjust the TRIM for each Input so that the front panel OL
LED illuminates only occasionally during extreme peaks. The
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. The 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.
The LEVEL of each Input can now be adjusted as needed
without danger of blowing your speakers, or scaring the
neighbors, whichever you deem worse.
STEREO LINE LEVEL INPUTS 7/8 and 9/10
When a stereo source (CD, DVD, cassette, etc.) is
connected to Inputs 7/8 (or 9/10), the routing is as follows:
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 buttons are
engaged, a mono mix of INPUTs 7/8 (or 9/10) will be routed
to both the A and B Outputs.
The 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.
