the dual, 160 Watt built-in power amplifiers. These are switching jacks, and when you plug
into either AMP IN, you interrupt the internal flow of signals going from the outputs of the
main mixing bus to the inputs of the built-in power amps. This allows you to employ one of
the amplifiers to power your monitors while the other powers the main PA speakers. To
accomplish this, simply run a patch cord from the MONITOR LINE OUT jack to either the
AMP A or AMP B IN jacks, then connect the monitor speakers to the amp's outputs on the
back panel. (The dual power amps are normally both on the output of the MAIN bus). You
may also use the AMP A and AMP B IN jacks to insert a speaker processor, another EQ or
compressor/limiter into the main (and/or monitor) signal path. This is accomplished by con-
necting a patch cable from the MAIN (and/or MONITOR) LINE OUT jack to the device's input
jack, and one or two patch cables from the device's output jack to either or both of the
MP8D's AMP IN jacks. It is even possible to connect another mixer to the MP8D's power
amplifiers via the AMP IN jacks. This slaves the amplifiers to that mixer's signals (i.e. it no
longer receives the built-in mixer's signals), which means that you could use the built-in mixer
to do another, totally separate, mixing job. For example, you could patch the MP8D's LINE
OUT signal to an input on another mixer connected to amps driving a PA speaker system
while using the MP8D's amplifiers to power control room speakers or monitors.
6. MONITOR LINE OUT JACK
The monitor bus output signal is available at line level (not speaker level) from the MONITOR
LINE OUT jack and would normally be patched to the input of a mono power amplifier, or
one channel of a stereo amp driving monitor speakers. Keeping in mind that there is no inter-
nal equalization for the monitor mix, you might want to patch a graphic equalizer between the
MONITOR OUT jack and the input of your monitor power amplifier to help regulate feed-
back. As mentioned under the previous section, the monitor mix signal can alternately be
patched to either of the internal amplifiers via the AMP IN jacks.
Patching something between things, in this case, means connecting the MP8D's MONITOR LINE
OUT jack to the input of an EQ and the output of the EQ to the input of a monitor power amp or
the AMP A or B IN jack.

4. MONITOR EFFECTS MASTER CON-
TROL
The MONITOR EFX master control regulates the
amount of signal going from the output of the
internal DIGITAL EFFECTS PROCESSOR to the
MONITOR mixing bus where it is mixed with
the dry signals direct from the channel MON
send controls. It controls overall effects intensity
of the MONITOR LINE OUT signal.
5. MAIN LINE OUT and AMP A & B IN
JACKS
These jacks can serve a variety of patching and
routing purposes. They are positioned in the sig-
nal path after the MP8D's main graphic equalizer
and are therefore regulated by it (i.e. they are
post-EQ). The main bus signals are available at
line level (not speaker level; use the SPEAKER
outputs on the back panel to drive speakers) from
the MAIN LINE OUT jack. Taking a signal from
this jack has no effect on the operation of the
MP8D's dual, built-in power amplifiers. It is
therefore possible to feed an external power
amplifier or even several, interconnected power
amps, with the MAIN output signals while the
internal power amplifiers are also functioning
(although, it is not necessary to have speakers
connected e.g. if you want to use the MP8D
strictly as a mixer).
The AMP A and B IN jacks are direct inputs to
