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.
ProFXv2 Series mixers have a universal power supply
that accepts any AC voltage ranging from 100 VAC to 240
VAC. 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 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 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 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
[ProFX16v2, ProFX22v2 and ProFX30v2].
The ProFX8v2 and ProFX12v2 USB return
only goes to main L/R via the USB input level
control.
The USB routing capabilities are as follows:
USB input TO the mixer – playback:
(1) Stereo channel 15/16 (on the ProFX16v2),
21/22 (on the ProFX22v2) and 29/30 (on the
ProFX30v2) 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 [ProFX16v2,
ProFX22v2, ProFX30v2] features a switch to select
either a “Tape” source (such as an iPod
®
connected
via RCA cables) or the USB signal from a computer
(playing Windows Media Player
®
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.
