Rear of the Mixer

Here's what you'll find at the rear of the mixer.

1) Power Input

Here's where you plug in your mixer's external power supply. You
should always connect your power supply to the mixer before you
plug the power supply into an electrical outlet.

Power Supply Unit:

This unit provides 18VAC at 1200mA x2 of power. As
with nearly all power supply units, this one tends to get
warm when left on for a while. This is perfectly normal.

2) POWER ON

Another easy one. Switch this one on and your mixer has power.
Switch it off and it doesn't. Make sure the faders in the master
section are pulled all the way down when powering your mixer up
or down.

3) PHANTOM ON

This switch activates and deactivates the phantom power
described in "Mic Inputs (Channels 1 – 8)," page 13. This
switch controls phantom power for all four mic inputs.

4) USB Port

This port allows you to connect the iMultiMix USB to a computer
for 2-way, stereo digital audio communication.

The POWER INPUT is built
to accept only the power
supply unit provided with
your iMultiMix USB, or an
AC power supply that has the
same specs. Others probably
will not work.
As we said earlier, it's very
important that you plug in
your microphones and mute
your system before you turn
on phantom power.
