3regulates the intensity of the built-in digital effects for the channel’s output. When using thebuilt-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 notrequire any effects at all, the effects bus output signal can be connected to the inputof 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 controlswould 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 ControlsThe signal balance of each channel going to the left and right main PA channels can beadjusted by the Pan control in channels 1 to 6, and by the Bal control in channels 7/8 and9/10. Turning this control counterclockwise towards the L will increase the signal level inthe left channel to a maximum of 3 dB while also reducing the level in the right channel tozero. Turning the control clockwise towards the R will increase the signal level in the rightchannel while also reducing the signal level in the left channel.Master Section1. MAIN Master ControlThe MAIN master control adjuststhe overall level of the main mix,the PA volume.Note: To ensure maximum sig-nal headroom and clarity, set thechannel TRIM and LEVEL con-trols first for a good signal with-out clipping, then set the masterfor the overall volume desired.2. MON Master ControlThe overall level of the monitormix is adjusted with the MONmaster control.Note: As with the MAIN mas-ter, set the MON master todeliver the desired volume aftersetting the channel sends.3. MAIN EFFECTS Return ControlThe 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 signalsdirectly. It controls the intensity of the effects on the left and right MAIN output signals.4. MON EFFECTS Return ControlThe MON EFX control regulates the amount of signal going from the output of the internal DigitalEffects Processor to the MON mixing bus where it is mixed with the dry signals directly from thechannel MON send controls. It controls the overall effects intensity for the MON Out signal.5. Pre-EQ OUT, Post-EQ OUTThese jacks offer a variety of patching and routing options. They are positioned in the signalpath 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 panelto 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 evenmultiple 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 asa 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 leftchannel only as soon as a jack is inserted in the R Pre-EQ jack. The Post-EQ OUT jacks arenot linked in this manner. They follow the operation of the Main/Mon switch described below.MONEFXReturnMAINEFXReturnMain/MonLeft /RightHALLSGATESCHAMBERSDELAYSROO MSEFXM O D I F Y E F XE Q U A L I Z E R A E Q U A L I Z E R BA RoomsB Rooms+Thickening DelaysC Rooms+Regen DelaysD Rooms/Halls+ChorusE HallsF Halls+Thickening DelaysG Halls+Regen DelaysH Gates/Reverse ReverbI ChambersJ Chambers+Thickening DelaysK Chambers+Regen DelaysL Short DelaysM Medium DelaysN Long DelaysO Delays+ChorusP Special EffectsMAINMON052 876439110052 876439110052 876439110052 876439110052 876439110052 876439110+15+10+50-5-10-15+15+10+50-5-10-15160 250 400 630 1.0K 1.6K 2.5K 4.0K 6.3K 160 250 400 630 1.0K 1.6K 2.5K 4.0K 6.3KPA OB NC MD LE KF JG IH161 152 143 134 125 116 107 98-15 +15 -15 +15 -15 +15 -15 +15clipA BRecOutAmpAssignClip/Protect48V PhantomPower OnPowerTape/CDLo Hi Lo Hi
