Connections
1. POWER CONNECTION
This is a standard 3-prong IEC power connector.
Connect the detachable linecord (included in the box
with your mixer) to the power receptacle, and plug
the other end of the linecord into an AC outlet. ProFX
Series mixers have a universal power supply that
accepts
anyACvoltagerangingfrom100VACto240VAC.
No need for voltage select switches. It will work virtually
anywhere in the world. That’s why we call it a “Planet-
Earth” power supply! It is less susceptible to voltage sags
or spikes, compared to conventional power supplies, and
provides greater electromagnetic isolation and better
protection against AC line noise.
Disconnecting the plug’s ground pin is
dangerous. Don’t do it.
2. POWER Switch
Press the top of this rocker switch inwards to turn on
the mixer. The front panel power LED [36] will glow
with happiness...or at least it will if you have the mixer
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 some 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, you should turn on your
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 your speakers.

3. USB INPUT/OUTPUT
The built-in USB interface allows for some
powerful and flexible routing. It is a 2x2 interface
allowing you to record two streams from the mixer, or to
input stereo playback from a computer and route it to
nearly any output or pair of outputs on the mixer.
The USB routing capabilities are as follows:
USB input TO the mixer - playback:
(1) Stereo channel 15/16 (on the ProFX16) and
21/22 (on the ProFX22) features a USB button, so one
may route computer output (such as iTunes
®
) down the
last stereo channel of the board. This stereo signal may
then be EQ'd, sent to auxiliaries (i.e. to feed monitors,
headphones or effects) and is routable to mains and/or
subgroups via the fader routing features that are
available on all other channels. In short, this signal may
be sent to nearly any desired output or pair of outputs.
Additionally, the gain knob at the top of this channel
strip adjusts the USB input level to the mixer to achieve
an optimal signal level.
(2) The 2-Track Return section features a flip switch,
so a “Tape” source (such as an iPod
®
connected via RCA
cables) or the USB signal from a computer
(playingWindowsMediaPlayer
®
files, for example) may
be routed to the main bus. This section also features an
input level adjustment for fading house music up and
down between bands, at a house of worship, or any other
event where this may be necessary.
