APPLICATIONS
The following are but a few of the many ways the MO-Series mixers can be used. While we have illustrated the MQ802, MO1202
and MQ1602 in specific sound systems, any of these mixers may be interchanged. As you become familiar with your mixer, you
will undoubtedly devise your own unique setups and operating techniques.

amplifier's speaker-level output
and the mixer's channel

In situations where a high impedance
source
(mic or line) is
used by one performer, and a low impedance source by a subsequent
performer,
the

can
both
be

to
a single
channel's inputs; the Input Selector switch can then be used for rapid
changeover between
the sources. This extends the input capacity and
avoids the need to unplug and reconnect cables.
The system illustrated uses a single channel of foldback (with optional
external graphic EQ), and has both a reverb and а delay line; only one
effect at a time is used, with the unused effect being turned off via its

The sound system illustrated is stereo, with Left and Right program
outputs driving identical amplifiers and speakers. In a monaural sound
system,
the
two
program
outputs
can
be
used
differently.
For
example, PGM
L can be used for the house feed, while PGM R is used
for a second foldback or echo/effects mix. In larger monaural
sound
systems, one program
output can be used for the "near stage" ampli-
fier cluster, and
the other
for a more
distant speaker cluster
(the
distant speakers
would
include a delay line between
the mixer and
amplifier to keep the acoustic image located on stage).
Note that the Program Sub Inputs can be used as auxiliary line inputs
for playing a stereo tape recording
(or a preamplified record). This
setup does not detract from the available input channels, and is useful
during setup, or for playing background music during an intermission.
