Note: It is not necessary to have speakers connected if you’d like to use the unit
strictly as a mixer. If a mono signal is required, possibly to feed a mono-house PA or
another amp/speaker system, use the L/Mono Pre-EQ jack. Mono operation of this
jack is switched to left channel only as soon as a jack is inserted in the R Pre-EQ
jack. The Post-EQ OUT jacks are not linked in this manner. They follow the operation
of the Main/Mon switch described below.
6. Power AMP IN Jacks
The Power AMP A IN and Power AMP B IN jacks are direct inputs to the built-in power ampli-
fiers. 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 accomplished 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 interrupted. This interrupts the signal from the M810/M1610 mixer to the built-in
power amplifiers allowing 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 (or Pre-EQ OUT) to the device’s input jacks and then from the
device’s output jacks to the M810/M1610 Power AMP A IN and Power AMP B IN jacks.
You can connect another mixer to the M810/M1610 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 M810/M1610 L and R Pre-
EQ OUT (or Post-EQ OUT) to inputs on another mixer connected to other amplifiers driving a PA
speaker system while using the M810/M1610’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, located just below the MAIN 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 amplifier (or a single
channel of a stereo amp) driving
stage monitor speakers. Keep
in mind that in the Left/Right
position of the Amp Assign
switch there is no internal equal-
ization 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 men-
tioned under #5. Pre-EQ OUT, 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 7/8 (channel 9/10 or any of
the other channels). Use the LEVEL 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 could 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.
