ProFX4v2 Rear Panel Features

1. Power Connection

Push the 2-pin female side of the power adaptor
securely into the connector on the rear of the mixer.
Plug the other end into an AC outlet properly configured
with the correct voltage as indicated on the AC adaptor.
Only use the AC adapter that came with your
mixer, or a factory-authorized power supply.

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's AC
adaptor 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 external
power supply is still live. To remove power, either turn
off the mains supply, or unplug the AC adaptor from
the mixer and the 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.
