A Tour of the MultiMix
Line Inputs (Channels 5 – 12)
Unlike channels 1 – 4, the line inputs on channels 5 – 12 are stereo
inputs that have left and right inputs. If you're using one of these
channels as a mono input, plug your instrument into the left input.
Channels 5 – 12 don't have the extra gain found on channels 1 – 4
because most line-level instruments don't require the extra boost.
Synthesizers and other electronic instruments will work especially
well on these channels. These inputs are also good for connecting
CD players or tape decks, as these audio sources don't require
extra gain.

Digital Output Jack

(Multimix-12FXD and Multimix-16FXD only)
The digital output jack is used to send the 44.1 kHz stereo audio
signal to an Alesis Masterlink or any other recording device such as
a DAT recorder or a PC with an S/PDIF enabled sound card
installed.
Always use a high quality cable when connecting the DIGITAL
OUTPUT JACK to your recording device. We recommend that
you use a cable that is specifically designed to carry a digital signal
and does not exceed 5 meters (16.4 ft) in length.

PHONE Jack

The headphone jack accepts 1/4" jacks. If your headphones are
1/8", you can find a 1/8" to 1/4" adapter in most electronics
stores.

AUX RETURNS

These are the 1/4" jacks where you connect the outputs of an
external effects processor or other audio source. Each aux return
gives you 15dB of gain that can be controlled by the AUX RET A
and EFFECTS / AUX RET B LEVEL knobs in the mixer's
output section.

AUX SENDS

And this is the 1/4" jack where you connect the line that's going
into the input of an external effects processor. The aux sends give
you 10dB of gain that can be controlled in the AUX section of
each channel input.

ALT 3/4 OUT

These jacks are the outputs for the MultiMix's extra stereo bus.
This signal includes channels whose MUTE / ALT 3/4 switch is
activated.

Any audio signal that is
routed to the MAIN
OUTPUTS will also be sent
out of the DIGITAL OUTPUT
jack. The level is controlled
by the MAIN FADERS. The
DIGITAL OUTPUT mirrors
the output from the MAIN
OUTPUTS.
If you are using an effects
device with only a mono
output, plug it into the left
return of STEREO AUX
RETURN. It will appear in
the center of the stereo
spectrum, and not to the left.
