2TK TO CTRL ROOM Switch
When you engage this switch, the signal coming in from the 2-
TRACK jacks is routed to the headphones and to the control
room output. This level is controlled by the HDPH / CTRL
ROOM level control and cancels out any signal from the main mix.
AUX RETURN A LEVEL
This is the level control for the signal returning to the mixer via
AUX RETURN A.
EFFECTS / AUX RET B LEVEL
If you are using one of the MultiMix 8 USB’s internal effects, this
knob controls the effect level. If AUX SEND B is connected to an
external device, this knob controls the level for AUX RETURN B.
LED Meters
These are the two rows of yellow, green and red lights you see in
the master section of the mixer. The LED meters allow you to
view the signal level of the main mix and 2-TRACK IN depending
on which signal you have routed to the control room mix.
POWER Indicator
When this LED is lit up, that means the POWER ON switch on
the rear of the mixer has been activated.
+48V Indicator
When this one is lit up, that means the PHANTOM ON switch on
the rear of the mixer has been activated and is supplying +48V
phantom power to all XLR mic inputs.

Rear of the Mixer
Here’s what you’ll find at the rear of the mixer.
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 18.5 VAC at 700 mA, more than enough to
keep your MultiMix 8 USB running smoothly. As with nearly all
power supply units, this one tends to get warm when left on for a
while. This is perfectly normal.
Power On
Another easy one. Switch this one on and your mixer has power.
Switch it off and it doesn’t. Make sure that all master output knobs
are turned all the way down when powering your mixer up or
down.
Phantom On
This switch activates and deactivates the phantom power
described in “Mic Inputs (Channels 1 – 4),” page 9. This switch
controls phantom power for all four mic inputs.
USB port
This port allows you to connect the Multimix 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 MultiMix 8 USB, or an
AC power supply that has the
same specs. Others probably
will not work.
A
s we said earlier, it’s very
important that you plug in
your microphones and mute
your system before you turn
on phantom power.
