Digital Effects Processor
1. Select EFX Control
Use the EFX Selection control to choose from the sixteen
24-bit digital reverbs, delays and other effects. This con-
trol rotates continuously, which lets you rotate clockwise
or counter-clockwise to select the desired effect. For con-
venience, a table of the effects and their variables appear
later in this manual and on the front panel of the MM5D.
2. Effects Clip LED
Situated to the left of the MODIFY EFX control, the CLIP
LED indicates that the digital processor is receiving an
input signal that is too large, resulting in distortion. For
optimum performance, the CLIP LED should never flash. If
there is clipping activity, turn down the channel EFX level
controls appropriately.
3. Effects Tables
See rear inside cover for the Digital Effects table.
Built in 7-Band Graphic
Equalizer
1. General
The GRAPHIC EQUALIZER consists of
seven +/-15dB range type controls. The
100Hz, and 250 Hz controls adjust the
bass region of the music (bass guitar,
kick drum). The 500Hz, 1kHz, and 2kHz
controls adjust the midrange region of
the music (vocals, keyboards, guitars).
The last two controls 5kHz, and 10kHz
adjust the treble region of the music
(drum cymbals, and overall brightness).
Note: Equalizers have an effect on the gain of the main system as well as its fre-
quency response. Once adjusted, you may need to adjust the MAIN level control if
the VU-Meter Clip LED flashes.
2. Reducing Feedback with the Graphic EQ
A technique used to help reduce feedback uses the GRAPHIC EQUALIZER. Turn the
MAIN level control up to the point of feedback and watch for one of the LEDs located
on the end of the GRAPHIC EQUALIZER sliders to turn on. When the specific slider
LED turns on, slide the slider down 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. If this occurs move the microphones away from the loudspeakers, and turn
down the CHANNEL LEVEL of any microphones not used by performers at that time.
