Led Meters; Power Indicator; +48V Indicator; Rear Of The Mixer - Alesis MultiMix12FX Reference Manual

LED Meters

These are the two rows of yellow, green and red lights you see in
the master section of the mixer. They are very versatile, allowing
you to view the signal level of the main mix, individual channels
(both pre- and post-fader) and aux returns 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 of power, more than
enough to keep your Multimix 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 the faders in the master
section are pulled all the way down when powering your mixer up
or down.
The POWER INPUT is built
to accept only the power
supply unit provided with
your MultiMix, or an AC
power supply that has the
same specs. Others probably
will not work.
