Master Input and Output Section
The mixer's Master Input and Output section has the connectors for interfacing the PHONES,
FOOTSWITCH, MAIN OUT, MAIN OUT 2, MAIN INSERT POINTS, AMP IN, and the master AUX
outputs.
H. FOOTSWITCH (¼" jack) - Connect a footswitch to
this jack to turn on and off the on-board digital
effects.
I. EFX OUT 1 & 2 (¼" jack) - These outputs are used
to send signals to external signal processors. The
signal present at the EFX 1 output is sent from
the AUX 3 bus, and the signal preset at the EFX 2
output is sent from the AUX 4 bus.
J. AMP IN Left & Right (¼" jacks) -The Left and Right
AMP IN ¼" phone jacks are used to make a direct
connection to the internal power amplifiers. You
can connect a stereo source like the output from
an external mixer here.
K. MAIN INSERT Left & Right (¼" Send and Return jack) - Send and return patch point on TRS
(TIP/RING/SLEEVE) jack for interfacing external effects processors on Left and Right MIX
bus. The signal is sent on the tip (the Send) and returns (the Return) on the sleeve of the
connector.
L. PHONES (¼" jack) - Connect standard stereo headphones, 60 to 600 Ohms.
M. MONO/SUB OUT (¼" jack) - The Left and Right Mix outputs are summed together and sent to
the unbalanced MONO/SUB output. The volume of the Mono signal can be adjusted using
the MONO/SUB OUT level fader control. For added flexibility, the MONO/SUB OUT can be
used to a feed a subwoofer using the onboard variable Low Pass Filter.
N. AUX OUT 1 & 2 (¼" jacks) - The signal present at the AUX 1and Aux 2 outputs are sent from
the AUX 1 and AUX 2 bus, which is fed from the AUX 1 and AUX 2 control knobs on the
input channels. The AUX 1 and AUX 2 are normally used as a MONITOR MIX bus in a live
sound situation by connecting the output to a power amp and monitor speaker.
O. MAIN OUT (¼" jacks) - These line level MAIN OUT jacks can be connected to drive a second
speaker system. The signal at the MAIN OUT jacks follows the MAIN volume fader.
P. MAIN OUT 2 (¼" jacks) - These line level MAIN OUT 2 outputs can be used to drive a second
speaker system or connect to a stereo device such as computer sound card, MP3, or record-
er.
The signal at the MAIN OUT 2 jacks follows the MAIN OUT 2 level control knob allowing
you to set a different level to the recorder.
