6. Channel EFX Controls
The EFX control (effects send) for each channel adjusts the level of the channel signal
being sent to the M810/M1610 effects bus. This signal is post-LEVEL control and post-EQ,
the sound is affected by both the channel EQ controls and the channel LEVEL control. The
signal from the effects bus is internally routed to the Digital Effects Processor. The chan-
nel EFX control regulates the intensity of the built-in digital effects for the channel’s out-
put. 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 information see the section EFX Out/Footswitch in this manual.
Tip: Alternatively, this signal at this jack can be connected to the input of an external 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 channel LEVEL controls also affect this signal.
7. Channel Pan and 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 over-
all level of the main mix, the PA volume.
Note: To ensure maximum signal head-
room and clarity, set the channel TRIM
and LEVEL controls first for a good sig-
nal without 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 master, 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.
Note: The Pre-EQ Out and the Post-EQ-Out signals include the effects return signal.
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.
