Rear Panel Features
1. POWER CONNECTION
This is a standard 3-prong IEC AC power connector.
Securely connect the supplied detachable linecord here
and plug the other end into an AC outlet. The mixer has
a universal power supply that may accept any AC voltage
rangingfrom100VACto240VAC.Noneedforvoltage
select switches or step-up or step-down transformers;
it will work virtually anywhere in the world. It is less
susceptible to voltage sags or spikes than conventional
power supplies and provides greater electromagnetic
isolation and better protection against AC line noise.
2. POWER SWITCH
Press the top of this rocker switch to turn on the
mixer. The front panel power LED [32] will glow with
happiness...or at least it will if the mixer is plugged into
a suitable live AC mains supply.
Press the bottom of this switch to put the mixer into
standby mode. It will not function, but the circuits are
still live. To remove AC power, either turn off the AC
mains supply, or unplug the power cord from the mixer
and the AC mains supply.
As a general guide, turn on the mixer first,
before any external power amplifiers or
powered speakers, and turn it off last. This
will reduce the possibility of any turn-on or turn-off
thumps in the speakers.
3. XLR MAIN OUTS
These XLR connectors provide stereo line-level
signals from the main mix. Connect these to the
balanced inputs of the powered speakers, or to the
power amplifier powering the main speakers.
The main mix is the sum of all active channels
currently playing, including any 2-channel USB input
fromthecomputer.Howmuchofachannelthatis
heard in the main mix is determined by that channel’s
fader [30].

TheXLRoutputsare6dBhigheroutputthan
the1/4"TRSmainoutputs[14].Balanced
connections offer better immunity to external
noise (specifically, hum and buzz) than unbalanced
connections. Because of this, it is the preferred
interconnect method, especially where very long
lengths of cable are being used.
4. USB PORT
The USB serial I/O interface allows digital audio to
transfer to and from a computer.
The interface provides two audio outputs to the
computer:
• Mainmixoutput,leftandright.Theseoutput
signals are independent of any adjustments
made to the main fader [47] and graphic EQ
[36].Thisallowsyoutoeasilyrecordlive
performance directly to a laptop.
• TheUSBthruswitch[40]allowsyoutoalso
include the output from your computer in your
recording. See page 23 for more details of this
switch.
The computer may also playback two channels into
the mixer via the USB interface:
• Leftandrightsignalsfromthecomputerare
added to the main mix. The USB input level
control [39] allows you to adjust the level of
the incoming audio from the computer being
added to the main mix.
