r 2TR IN
These RCA pin jacks can be used to input a stereo sound 
source. Use these jacks when you want to connect a CD 
player, and output the signal to the monitor or the STEREO 
L/R bus.
NOTE
You can adjust the signal level using the 2TR IN control in the 
Master Control block.
t REC OUT
These RCA pin jacks can be connected to an external 
recorder such as an MD recorder in order to record the same 
signal that is being output via the STEREO OUT jacks.
NOTE
The mixer’s STEREO master fader has no affect on the signal 
output via these jacks. Be sure to make appropriate level 
adjustments at the recording device.
y MONITOR OUT
Connect these impedance-balanced* TRS phone jacks to 
your monitor system. These jacks output the signal before or 
after the faders for the various buses. The PFL and AFL indi-
cators in each section indicate which signal is being output.
NOTE
The PFL switch has priority when both the PFL switch and AFL 
switch are on. To monitor the post-fader signal, make sure to 
turn off all PFL switches.
u RETURN
These are unbalanced phone-jack type line input jacks. The 
signal received by these jacks is sent to the STEREO L/R 
buses and the AUX1 and AUX2 buses. The mixed signal of L 
(MONO) and R is sent to the AUX1 and AUX2 buses.
These jacks are typically used to receive the signal returned 
from an external effect device (reverb, delay, etc.).
NOTE
• These jacks can also be used as an auxiliary stereo input.
• If you connect to the L (MONO) jack only, the mixer will rec-
ognize the signal as monaural and will send the identical sig-
nal to both the L and R jacks.
i GROUP OUT
These impedance-balanced* TRS phone jacks output the 
GROUP 1-2, 3-4 signals. Use these jacks to connect to the 
inputs of a multi-track recorder, external mixer, or another 
similar device.
o SEND
You use these jacks, for example, to connect to an effect 
device or monitor system.
• AUX1, AUX2: These are balanced XLR-3-32 type out-
put jacks (1: Ground; 2: Hot; 3: Cold).
• FX1, FX2: These are impedance balanced* phone-
jack type output jacks. These jacks output the 
signals from the FX1 and FX2 buses, respec-
tively.
!0 STEREO OUT
These are XLR type and TRS phone type balanced output 
jacks that output the mixed stereo signal. The signal level is 
adjusted by the STEREO master fader before it is output. You 
can use these jacks, for example, to connect to the power 
amplifier driving your main speakers.
Power section
!1 POWER switch
Turns power to the unit ON or OFF. Press the switch to the 
“ ” position to turn on the power. Press the switch to the 
“ ” position to turn off the power.
CAUTION
Rapidly turning the unit ON and OFF in succession can 
cause it to malfunction. After turning the unit OFF, wait for 
about 6 seconds before turning it ON again.
!2 AC IN connector
Connect the included power cord here. First, connect the 
power cord to the MGP, and then plug it into an AC outlet.
* Impedance balanced
Since the hot and cold terminals of impedance balanced 
output jacks have the same impedance, these output jacks 
are less affected by induced noise.
