1
SEND Jacks (AUX, EFFECT)
These impedance balanced* TRS phone jacks output the sig-
nals from the AUX/EFFECT buses. The pre-fader send option
should be selected if you are connecting to a monitor system,
while the post-fader send option is the best choice when con-
necting to external signal processors (e.g. effects units).
See "AUX, EFFECT Control" on page 14 for information on
the types of signals sent by the AUX and EFFECT controls
on each mixer model.
2
GROUP OUT (1 to 4) Jacks
These impedance-balanced* TRS phone jacks output the
GROUP 1/2 and 3/4 signals. Use these jacks to connect to
the input jacks of an multi-track recorder, external mixer, or
other such device.
3
REC OUT (L, R) Jacks
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.
The mixer's STEREO OUT Master fader has no
NOTE
affect on the signal output via these jacks.
Be sure to make appropriate level adjustments at the
recording device.
4
2TR IN Jacks
These RCA pin jacks input a stereo sound source.
Use these jacks when you want to connect a CD player
directly to the mixer.
Select where you want to send the signal using the
NOTE
2TR IN switch, and adjust the signal level using the
2TR IN control in the Master Control section.
5
RETURN L (MONO), R Jacks
These are unbalanced phone-jack type line inputs.
The signal received by these jacks can be sent to the STE-
REO L/R bus as well as the AUX1 and AUX2 buses. When a
stereo signal is returned a mono mix of the signal 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.).
• These jacks can also be used as an auxiliary ste-
NOTE
reo input.
• If you connect to the L (MONO) jack only, the mixer
will recognize the signal as monaural and will send
the identical signal to both the L and R jacks.
6
STEREO OUT (L, R) Jacks
These jacks deliver the mixer's stereo output. You use these
jacks, for example, to connect to the power amplifier driving
your main speakers. You can also connect these jacks to a
recording device when you wish to record mixer's stereo
output while using the STEREO OUT Master fader
level control.
• XLR jacks
XLR-type balanced output jacks.
• LINE jacks
TRS phone-type balanced output jacks.
7
MONITOR OUT jacks
These are impedance-balanced* TRS phone-type output
jacks.
The signal output by these jacks is determined by the
NOTE
MONITOR switch, the 2TR IN switch, and the PFL
switches on the input channels.
8

PHONES Jack

Connect a pair of headphones to this TRS phone-type output
jack. The PHONES jack outputs the same signal as the
MONITOR OUT jacks.
9
PHANTOM +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. Turn this switch on
when using one or more phantom-powered condenser micro-
phones.
When this switch is on the mixer supplies DC +48 V
NOTE
power to pins 2 and 3 of all XLR-type MIC INPUT
jacks.
• Be sure to leave this switch off if you do not
need phantom power.
CAUTION
• When turning the switch on, be sure that only
condenser microphones are connected to the
XLR input jacks. 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 bal-
anced dynamic microphones.
• To prevent damage to speakers, be sure to turn
off power amplifiers (or powered speakers)
before turning this switch on or off. We also
recommend that you turn all output controls
(STEREO OUT Master fader, GROUP 1-2 fader,
GROUP 3-4 fader, etc.) to their minimum set-
tings before operating the switch to avoid the
risk of loud noises that could cause hearing
loss or device damage.

POWER Indicator

This indicator lights when the mixer's power is ON.
A

Level Meter

This LED meter displays the level of the signal selected by
the MONITOR switch
switch. The "0" segment corresponds to the nominal output
level. The PEAK indicator lights red when the output
reaches the clipping level.
B
RETURN
• AUX1, AUX2 Control
Adjusts the level at which the L/R signal received at the
RETURN jacks (L (MONO) and R) is sent to the AUX1 and
AUX2 buses.
• STEREO Control
Adjusts the level at which the signal received at the RETURN
I
for
jacks (L (MONO) and R) is sent to the STEREO L/R bus.
• If you supply a signal to the RETURN L (MONO)
NOTE
jack only, the mixer sends the same signal to both
the L and R STEREO buses.
• (MG206C) Signals input via the RETURN1 jacks
are adjusted using the RETURN1 AUX1, AUX2 and
the STEREO controls, and signals input via the
RETURN2 jacks are adjusted using the RETURN2
AUX1, AUX2 and the STEREO controls.
* 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.
