6. Power AMP IN Jacks
The
Power AMP A IN
and
Power AMP B IN
jacks
are direct inputs to the
built-in
power amplifiers.
They are referred to as
A
and
B
rather than left
and right simply because it is possible to power
both main PA speakers with one amplifier channel
and monitors with the other. This can be accom-
plished by selecting the
Main/Mon
position on
the selector switch located
between
the graphic
equalizers. In the
Left/Right
position,
Power AMP A
receives the left signal while
Power
AMP B
receives the right signal. In the
Main/Mon
position,
Power AMP A
receives a mono
sum of left and right signals while
Power AMP B
receives the monitor signal. An alternative
use for the
Power AMP A IN
and
Power AMP B IN
jacks would be as patching inputs. Since
they’re switching jacks if you plug into one (or both) the internal signal flow will be inter-
rupted. This interrupts the signal from the
M608
mixer to the
built-in
power amplifiers allow-
ing you to insert signal control devices such as an
élite
processor, an additional equalizer,
or a compressor/limiter into the main stereo signal path. Connect cables from the
L
and
R
Post-EQ OUT
to the device’s input jacks and then from the device’s output jacks to the
M608
Power AMP A IN
and
Power AMP B IN
jacks.
You can connect another mixer to the
M608
power amplifier through the
Power AMP A IN
and
Power AMP B IN
jacks. This slaves the amplifier to the other mixer’s signals; it no longer
receives the
built-in
mixer’s signals which means that you could use the
built-in
mixer to do a
totally separate mixing job. For example, you could patch the
M608 L
and
R Post-EQ OUT
to
inputs on another mixer connected to other amplifiers driving a PA speaker system while using
the
M608
’s
A
and
B
amps to power control room speakers.
7. Rec OUT Jacks
These phono connectors send the
L
and
R
pre-
EQ
,
pre-
EFFECTS
(not affected by the
MAIN EQ
) main mix signals. The
Rec OUT
control adjusts the signal level for these
jacks. Using phono patch cords, connect directly to the Auxiliary (line-level) inputs on a
tape deck or other recording device.
8. MON Out Jack
The monitor bus output signal from the
Mon OUT
jack is line level
and would normally be patched to the input of a mono power ampli-
fier (or a single channel of a stereo amp) driving stage monitor speak-
ers. Keep in mind that in the
Left/Right
position of the
Amp Assign
switch there is no internal equalization for the monitor mix (you
might want to patch a graphic equalizer between the
Mon OUT
jack
and the input of your monitor power amplifier, this can help regulate
the feed). As mentioned under
#4. Post-EQ OUT
section (
above
), the
monitor mix signal can also be patched to one channel of the internal
amplifier using the
Amp Assign
switch.
9. EFX Out / Footswitch Jack
Using this jack you can connect a standard on/off footswitch to
control the activation of the internal
Digital Effects Processor
or
it can be used as an effects send jack for use with an external
effects processor.
Note:
Both devices would be sent a signal, so you could connect the external unit’s
left and right outputs to the L and R inputs on channel 5/6 (channel 7/8 or any of
the other channels). Use the GAIN of that channel to adjust the amount of wet
signal added to the main mix and the MON control to adjust the amount of wet sig-
nal added to the monitor mix. Make sure that its EFX control on the channels are
turned off. An alternative would be to use the EFX Out / Footswitch jack to deliver
line level signal to the input of an auxiliary amplifier or even a recording device.
Here, the channel EFX controls would act as secondary level controls.
