Front & Rear Panels
7 SEND Jacks
• AUX1 and AUX2 jacks
These are impedance balanced phone-type output
jacks.
These jacks output the signals from the AUX1 and
AUX2 buses, respectively. Use these jacks to output
these signals to an effector or to a cue box or other
such monitoring system.
8 RETURN L (MONO), R Jacks
These are unbalanced phone-type line input jacks. The
signal received by these jacks is sent to the Stereo bus
and the AUX1 and AUX2 buses. These jacks are typically
used to receive a return signal from an external effector
(reverb, delay, etc.).
n These jacks can also be used as an auxiliary stereo
input. If you connect to the L (MONO) jack only, the
mixer will recognize the signal as monaural and will
propagate the identical signal on both L and R jacks.
9 REC OUT (L, R) Jacks
By connecting these jacks to an external DAT recorder or
cassette recorder, you can record the same signal that is
being output from the ST OUT jacks.
n • The mixer's ST Master Fader has no affect on the
signal output from these jacks. Be sure to make
appropriate level adjustments at the recording device
side.
• These connectors output the same signal that sent to
the computer via the USB interface.

• When a signal is being received both via the 2TR IN
connectors and the USB interface, the received
signals are mixed.
When connecting or disconnecting the USB cable
be sure to turn the 2TR IN/USB control all the way

Note that trace current continues to flow while the
switch is in the STANDBY position. If you do not
plan to use the mixer again for a long while, be
sure to unplug the adaptor from the wall outlet.
