regulates the intensity of the built-in digital effects for the channel’s output. When using the
built-in digital effects, you can connect a standard on/off footswitch (e.g. Yorkville model IFS-
1A) to the EFX Out/Footswitch jack to turn the internal effects on or off. For more informa-
tion see the section EFX Out/Footswitch in this manual.
Tip: Alternatively, this signal at this jack can be connected to the input of an exter-
nal stereo effects unit and returned via channel 7/8 or 9/10. However, if you do not
require any effects at all, the effects bus output signal can be connected to the input
of an additional monitor system or another amp/speaker system via the EFX Out/
Footswitch jack using a standard balanced patch cord. In this case, the EFX controls
would act as send controls to achieve a semi-separate mix. Remember that the chan-
nel LEVEL controls also affect this signal.
7. Channel Pan & Bal Controls
The signal balance of each channel going to the left and right main PA channels can be
adjusted by the Pan control in channels 1 to 6, and by the Bal control in channels 7/8 and
9/10. Turning this control counterclockwise towards the L will increase the signal level in
the left channel to a maximum of 3 dB while also reducing the level in the right channel to
zero. Turning the control clockwise towards the R will increase the signal level in the right
channel while also reducing the signal level in the left channel.
Master Section
1. MAIN Master Control
The MAIN master control adjusts
the overall level of the main mix,
the PA volume.
Note: To ensure maximum sig-
nal headroom and clarity, set the
channel TRIM and LEVEL con-
trols first for a good signal with-
out clipping, then set the master
for the overall volume desired.
2. MON Master Control
The overall level of the monitor
mix is adjusted with the MON
master control.
Note: As with the MAIN mas-
ter, set the MON master to
deliver the desired volume after
setting the channel sends.
3. MAIN EFFECTS Return Control
The MAIN EFX control regulates the amount of signal going from the output of the inter-
nal Digital Effects Processor to the MAIN mixing bus where it is mixed with the dry signals
directly. It controls the intensity of the effects on the left and right MAIN output signals.
4. MON EFFECTS Return Control
The MON EFX control regulates the amount of signal going from the output of the internal Digital
Effects Processor to the MON mixing bus where it is mixed with the dry signals directly from the
channel MON send controls. It controls the overall effects intensity for the MON Out signal.
5. Pre-EQ OUT, Post-EQ OUT
These jacks offer a variety of patching and routing options. They are positioned in the signal
path before and after the M810/M1610 main graphic equalizers.
These bus signals are at line level, not speaker level (use the SPEAKER outputs on the rear panel
to drive speakers). Using signals from these jacks has no effect on the operation of the M810/
M1610 built-in power amplifier. This makes it possible to feed an external power amplifier, or even
multiple inter-connected power amps, while the internal power amplifier is functioning.
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.
