Multimix 12R Reference Manual 13
Phonograph turntables
If you're using a record turntable, you may not plug it directly into the
line inputs of the Multimix 12R (well, you can, but it will sound very
thin and noisy). Obtain a phono preamp from your dealer or an
electronics specialty store.
1. Plug the outputs of the phonograph pickup into the RIAA-
equalized phono preamp.
2. Plug the outputs of the preamp into the LINE IN 9-10 or 11-12
inputs of the Multimix 12R.
Do not connect any of the following to any
input of the Multimix 12R!
• The speaker output of any power amplifier.
• Any source that is too loud for the input (no more than 3 volts RMS
into a [MIC] jack or 13 volts RMS into a [LINE IN] jack).
• Any unshielded cable.

How to connect effect devices and signal
processors
Alesis and other companies make many different types of signal
processors which may be connected to the Multimix 12R mixer. There
are two ways to connect these units: using the AUX system or via the
INSERT jacks.
Effects via Aux Send and Aux Return
If you want to add an effect such as reverb, chorus, or delay to several
different inputs at once, you will use the AUX system.
1. Connect the AUX 2 (POST) AUX SEND output of the 12R to the
input of the effect device. If the effect has a stereo input, check the
manual of the effect to see which jack is the mono jack. (In most
cases, you won't need to connect anything to the other input jack
of the device, but you will still get a stereo effect output).
2. Connect the left and right outputs of the effect device to the
[STEREO AUX RETURN] jacks of the Multimix 12R.
•
Alternatively, you may connect the output of the effect device to either of
the STEREO LINE channels ([9-10 or 11-12].) This will allow you to
control the effect with a large fader, send the effects to the Aux 1 output
for monitoring, and use EQ on the effect.
About stereo effect devices
✪ If your effect unit has two inputs, in most cases you need to connect from
only ONE Aux Send to the left (mono) input of the effect unit, but you will
still connect both the left and right outputs of the effect to the STEREO AUX
RETURN.
