Multimix 12R Reference Manual 19
To another mixer
The main or monitor outputs of the Multimix 12R may be connected to
a larger mixing console. Consult the manual for the other mixer for
more information. If the mixer has "SUB IN" jacks, connect to those.
Alternatively, you may simply connect the MAIN OUT or MONITOR
OUT jacks of the Multimix 12R to two line-level inputs on the other
mixer. If you do, check to see what level those inputs are designed for.
If the inputs of the other mixer can handle +4 dBu balanced or -2
dBu unbalanced levels, simply connect the [MAIN OUT
BALANCED] outputs to the other mixer's line inputs.
If the inputs are designed for -10 dBV level inputs (such as most
keyboard and guitar amplifiers, and consumer stereo amplifiers),
connect the [MAIN OUT -10 dBV] outputs to the line inputs of the
external mixer.
If the connection is made properly, the Multimix 12R will not distort
the input of the other mixer. You may need to adjust the input trim of
the other mixer to get the best dynamic range.
To a stereo tape recorder
If you want to record the output of the mixer into a typical stereo
cassette or DAT deck, connect the [MAIN OUT -10 dBV] phono jacks to
the left and right inputs of the cassette deck using a standard stereo
phono-to-phono (RCA) cable.
If your recorder is a professional type with balanced +4 inputs, in most
cases you should connect the [MAIN OUT BALANCED] jacks of the
mixer to the inputs of the recorder.
If you connect the [MONITOR OUT] jacks to the recorder, the level
will be affected by the [PHONES/MONITOR] level control on the front
panel. However, if you're using the [TAPE IN] jacks to monitor
playback, you run the risk of feedback if you press the MSTR/TAPE
switch while in record mode.

To an ADAT multitrack recorder
The studio-grade microphone preamplifiers of the Multimix 12R are
designed to rival or exceed the sound quality of external microphone
preamps costing many times more. A basic 8-track digital recording
system with an ADAT-XT and a Multimix 12R is portable, cost-
effective, easy to use, and sonically transparent. There are two ways
to use the Multimix 12R with ADAT: a single mixer with the ADAT
patched into the [INSERT] jacks, or using two Multimix 12Rs, one for
input and another for monitoring.
In-line ADAT recording:
In this hookup method, the ADAT is patched into the [INSERT] jacks
of channels 1-8 as if each track of the recorder were a signal processor
in each channel of the mixer. Since the ADAT is a unity-gain device, it
will not affect the levels going through the mixer. The [TRIM] control
is the only level control for the ADAT inputs; the channel faders, EQ,
and aux sends of the Multimix 12R are used for monitoring and will
not affect multitrack recording levels.
This method is recommended by many audiophiles and engineers,
since there is a minimum of circuitry between the original source and
the recorder. Hooking a Multimix 12R to an ADAT via the [INSERT]
jacks is effectively the same as connecting studio-quality microphone
preamps directly to the input of the tape deck.
NOTE: To hear the microphone or line input signal through the
mixer, the ADAT track must be in RECORD READY or INPUT mode.
See the ADAT manual for more details.
1. Obtain eight "stereo splitter" insert cables from your dealer. These
cables feature a three-conductor TRS ("stereo") 1/4" phone plug at
one end, and split out to two "mono" plugs at the other, as shown
below. If you have an ADAT, use 1/4" TRS to 1/4" mono cables. If
you have an ADAT-XT, use 1/4" TRS to phono cables.
