MG124CX/MG124C Owner’s Manual
Reference
Front & Rear Panels
The following applies to both the MG124CX and MG124C. In cases where different features need to be described for each
model, the MG124CX feature will be described first, followed by the MG124C feature in brackets: MG124CX (MG124C).
Channel Control Section
1 MIC Input Jacks (CHs 1 to 4, 5/6, 7/8)
These are balanced XLR-type microphone input jacks
(1:Ground; 2:Hot; 3:Cold).
2 LINE Input Jacks (CHs 1 to 4)
These are balanced TRS phone-jack line inputs (T:Hot;
R:Cold; S:Ground).
You can connect either balanced or unbalanced phone plugs
to these jacks.
3 LINE Input Jacks (CHs 5/6 to 11/12)
These are unbalanced phone-jack stereo line inputs.
4 LINE Input Jacks (CHs 9/10, 11/12)
These are unbalanced stereo RCA pin jacks.
Where an input channel provides both a MIC input
jack and a LINE input jack, or a LINE input jack and
an RCA pin jack, you can use either jack but not both
at the same time. Please connect to only one jack on
each channel.
5 INSERT Jacks (CHs 1 to 4)
Each of these jacks provides an insert point between the
equalizer and fader of the corresponding input channel (CHs
1 to 4). The INSERT jacks can be used to independently con-
nect devices such as graphic equalizers, compressors, or
noise filters into the corresponding channels. These are TRS
(tip, ring, sleeve) phone jacks that carry both the send and
return signal (tip = send/out; ring = return/in; sleeve =
ground).
Patching external devices via an INSERT jack
requires a special insert cable such as illustrated
below (insert cable sold separately).
6 GAIN Control
Adjusts the input signal level.
To achieve the best balance between S/N ratio and dynamic
range, adjust the level so that the PEAK indicator
9 lights
only occasionally and briefly on the highest input transients.
The –60 to –16 scale is the MIC input adjustment range. The
–34 to +10 scale is the LINE input adjustment range.

MG124CX
The signal output from the INSERT jacks is
reverse-phased. This should not be a problem
when connecting to an effect unit, but please be
aware of the possibility of phase conflict when
connecting to other types of device.
