Reference
8PHONES Jack
Connect a pair of headphones to this stereo phone jack. The
PHONES jack outputs the same signal as the MONITOR
OUT jacks.
9PHANTOM +48 V Switch
This switch toggles phantom power on and off. When the switch
is on the mixer supplies +48V phantom power to all channels
that have XLR mic input jacks (CHs 1–4, 5/6, 7/8).
Turn this switch on when using one or more phantom-pow-
ered condenser microphones.
When this switch is on the mixer supplies DC +48 V
power to pins 2 and 3 of all XLR-type MIC INPUT
jacks.
0RETURN

•AUX (AUX1) Control

Adjusts the level at which the L/R signal received at the
RETURN jacks (L (MONO) and R) is sent to the AUX
(AUX2) bus.

• STEREO Control

Adjusts the level at which the signal received at the
RETURN jacks (L (MONO) and R) is sent to the STEREO
L/R buses.
If you supply a signal to the RETURN L (MONO)
jack only, the mixer sends the same signal to both the
L and R Stereo buses.
AMaster SEND

•Master AUX (AUX1) Control

Adjusts the signal level sent to the AUX (AUX1) SEND jack.

•Master EFFECT (AUX2) Control

Adjusts the level of the signal sent to the EFFECT (AUX2)
bus.
If you are using the MG124CX, the Master EFFECT
control does not affect the level of the signal sent
from the EFFECT bus to the internal digital effect
processor.
BPOWER Indicator
This indicator lights when the mixer’s power is ON.
CLevel Meter
This LED meter displays the level of the signal selected by
the MONITOR switch D, 2TR IN switch E and PFL
switch. The “0” segment corresponds to the nominal output
level. The PEAK segment lights red when the output reaches
the clipping level.
DMONITOR/PHONES

• MONITOR Switch

If this switch is set to GROUP ( ), the Group 1/2 bus sig-
nals are sent to the MONITOR OUT jacks, the PHONES
jack, and the level meter. If it is set to STEREO ( ), the
STEREO L/R bus signals are sent to these jacks and the level
meter.

• MONITOR Control

Controls the level of the signal output to the PHONES jack
and the MONITOR OUT jacks.
E2TR IN

• 2TR IN Switch

If this switch is set to TO MONITOR ( ), the signals input
via the 2TR IN jacks are sent to the MONITOR OUT jacks,
the PHONES jack, and the level meter. If it is set to TO STE-
REO ( ), the signals are sent to the STEREO L/R buses.

• 2TR IN control

Adjusts the level of the signal sent from the 2TR IN jacks to
the STEREO L/R buses.
The following illustration shows how the switch settings cor-
respond to the signal selection.
*: When overdubbing, you can adjust the levels of the
monitor playback signal and the signal being recorded separately.
MONITOR MIX Signal Flow
If the input channel PFL switch is on ( ), then only
the PFL output from that channel is sent to the C-R
OUT jacks, PHONES jacks, and level meter.
FGROUP 1-2 Fader
Adjusts the signal level sent to the GROUP OUT jacks.
GST Switch
If this switch is on ( ), the signals are sent to the STEREO
L/R buses via the GROUP 1-2 fader

F

. The Group 1 signal
goes to Stereo L and the Group 2 signal goes to Stereo R.
HSTEREO OUT Master Fader
Adjusts the signal level sent to the STEREO OUT jacks.
•Be sure to leave this switch off ( ) if you do
not need phantom power.
•When tuning the switch on ( ), be sure that
only condenser mics are connected to the
XLR input jacks (CHs: 1 to 7/8). Devices
other than condenser mics may be damaged if
connected to the phantom power supply. Note,
however, that the switch may be left on when
connecting to balanced dynamic microphones.
•
To avoid damage to speakers, be sure to turn
off amplifiers (or powered speakers) before
turning this switch on or off. We also recom-
mend that you turn all output controls (STE-
REO OUT Master Fader, GROUP 1-2 Fader,
etc.) to their minimum settings before operat-
ing the switch to avoid the risk of loud noises
that could cause hearing loss or device damage.
