MLM 103 CONNECTION
INPUTS
The MLM 103 has ten balanced Euroblock Inputs. Use
only shielded cable. For best noise rejection use two-conduc-
tor-plus-shielded wire, even for unbalanced operation.
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 Euroblock connectors. Be sure to bite through the paint
with the star washer and keep the shields wrapped around the
audio conductors as mush as possible. For the “theoretical”
best ElectroMagnetic Interference (EMI) immunity, connect
the shields at both ends of the cables. (For more information
on connections, see RaneNote 110, “Sound System Intercon-
nection” later in this manual or on Rane’s web site.)
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
The MLM 103’s OUTPUTS (and DIRECT OUTPUTS)
are balanced. The same wiring conventions as the Euroblock
Inputs apply.
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
6
may be microphone or line level. The 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. The 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
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 the both the
A/B ASSIGN
and
MONO
buttons are engaged, both Inputs of
7/8
(or
9/10
) will route to both the
A
and
B
Output.
The
AUX ASSIGN
button is always a mono mix of the stereo channel.
