Digital Effects Processor
1. Select & MODIFY EFX Controls
The Select control selects from 16 banks of digital reverbs, delays and other effects. Simply
rotate 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 one
of these variations. For example, if bank M (Medium Delays) has been selected, position
1 on the MODIFY EFX control will give you 200 milliseconds of delay, and positions 2
through 16 will give you progressively longer delays up to 375 milliseconds. Bank P is the
exception to this rule. It consists of sixteen different special effects such as pitch shift up
or down, detune, flanger etc.
Note: The signal sent from the internal Digital Effects Processor to the MON mix is
independent from the MON send controls on the channel strips. When a channel’s
EFX control is sending signal to the internal
Effects processor and the MON control, for
that channel, is turned off, that channel’s wet
effects will be heard in the MON bus if the EFX
to Monitor return is turned up.
2. Effects CLIP LED
Situated to the right of the MODIFY EFX control,
the CLIP LED indicates that the digital processor is
receiving an input signal that’s too strong, resulting
in distortion. For optimum performance, the CLIP
LED should never flash. If there is clipping activity,
turn down the channel EFX controls appropriately.
3. EFFECTS TABLES
See rear inside cover for effects tables.
Built in 9-Band Graphic Equalizer & Shelving EQs
General
Each EQ consists of a set of +/-15dB range type controls. In the M810/M1610 there are
nine sliders for each channel, each one operating over a 2/3-octave portion of the midrange
band 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 frequency
response. Once adjusted, you may need to adjust the MAIN master level if the clip
LEDs become too active.
There Are 3 Main Functions for the Graphic EQ & Shelving Equalizers
i. To adjust the system to help reduce feedback, a normal technique is to turn the main
system 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 specific
frequency band is isolated, set it to about -3 to -5 dB. Usually only 2 or 3 bands can be
reduced before the feedback reduction process begins to affect the sound quality.
