6Digital Effects Processor1. Select & MODIFY EFX ControlsThe Select control selects from 16 banks of digital reverbs, delays and other effects. Simplyrotate the Select control to the basic type of effect you prefer. This control rotates continu-ously so you can rotate in either clockwise or counter-clockwise to select the desired effect.Lists of effects banks appear later in this manual and on the front panel of the M810/M1610. (The variations for the specific effects banks are listed later in this manual.)Each bank of effects contains 16 effect variations. The MODIFY EFX control selects oneof these variations. For example, if bank M (Medium Delays) has been selected, position1 on the MODIFY EFX control will give you 200 milliseconds of delay, and positions 2through 16 will give you progressively longer delays up to 375 milliseconds. Bank P is theexception to this rule. It consists of sixteen different special effects such as pitch shift upor down, detune, flanger etc.Note: The signal sent from the internal Digital Effects Processor to the MON mix isindependent from the MON send controls on the channel strips. When a channel’sEFX control is sending signal to the internalEffects processor and the MON control, forthat channel, is turned off, that channel’s weteffects will be heard in the MON bus if the EFXto Monitor return is turned up.2. Effects CLIP LEDSituated to the right of the MODIFY EFX control,the CLIP LED indicates that the digital processor isreceiving an input signal that’s too strong, resultingin distortion. For optimum performance, the CLIPLED should never flash. If there is clipping activity,turn down the channel EFX controls appropriately.3. EFFECTS TABLESSee rear inside cover for effects tables.Built in 9-Band Graphic Equalizer & Shelving EQsGeneralEach EQ consists of a set of +/-15dB range type controls. In the M810/M1610 there arenine sliders for each channel, each one operating over a 2/3-octave portion of the midrangeband of sound frequencies, as well as rotary shelving Bass and Treble controls.Note: Equalizers have an effect on the gain of the main system as well as its frequencyresponse. Once adjusted, you may need to adjust the MAIN master level if the clipLEDs become too active.There Are 3 Main Functions for the Graphic EQ & Shelving Equalizersi. To adjust the system to help reduce feedback, a normal technique is to turn the mainsystem up to the point of feedback and then adjust the EQ sliders individually to deter-mine which frequency band will reduce the potential of feedback. When the specificfrequency band is isolated, set it to about -3 to -5 dB. Usually only 2 or 3 bands can bereduced before the feedback reduction process begins to affect the sound quality.HALLSGATESCHAMBERSDELAYSROOM SEFXM O D I F Y E F XA 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 EffectsPA OB NC MD LE KF JG IH161 152 143 134 125 116 107 98 clipE Q U A L I Z E R A E Q U A L I Z E R B+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 6.3K-15 +15 -15 +15 -15 +15 -15 +15Lo Hi Lo Hi
