counterpoint or a background rhythm in the REPEAT HOLD mode. When your DIGITAL
MULTI-EFFECTS is initially powered up, an internal protection circuit defeats the REPEAT
HOLD function to prevent "howling."
3.4 DIGITAL FLANGER
(A) The DIGITAL FLANGER section uses a triangle wave for its sweep waveform and
offers delay times within the range of 0.5ms to 5ms for crisp, biting flange effects.
(B) The PHASE Invert switch allows you to produce positive and negative flanging which
resemble a "swooshing, jet-like" sound or a "hollow tunnel" effect.
(C) The MANUAL control sets the static (non-sweeping) delay time of the flanger.
Turning the DEPTH control clockwise from the "0" (off position) will bring the sweep
modulation into play. The sweep is centered around the delay time set by the
MANUAL control. Changing the position of the MANUAL control will change the bass
or treble emphasis of the flanging effect. As the DEPTH control is turned further
clockwise, a wider range of the delay time is swept. With the DEPTH control set at"
10", the full 10-to-1 range is swept and the position of the MANUAL control will have
no effect on the modulation.The RATE control adjusts the speed of the modulation
from 0.1 sec to 25sec for a complete sweep cycle. Slow sweeps are useful for
flanging and chorusing effects while faster sweeps can produce vibrato and rotating
speaker simulation.
(D) Increasing the REGEN level setting from "0" to "10" sustains sounds and adds
resonance to the flanged signal. As the REGEN control is turned clockwise, more of
the delayed signal is sent back to the input of the FLANGER increasing the intensity
of the effect.
3.5 DIGITAL CHORUS
The DIGITAL CHORUS section uses a smooth contoured sine wave and delay times within
the range of 2.5ms to 20ms for rich chorusing effects. (Please refer to section 3.4, C for
explanation of DEPTH and RATE controls.)
3.6 DIGITAL DELAY
The DIGITAL DELAY section offers a full compliment of controls to produce doubling,
slapback, repeat echoes, infinite repeat, and reverb effects.
The MIX control mixes the DELAY processed signal with the dry input signal. For use with
instruments, the control will most often be in its center range. For studio applications where
your DIGITAL MULTI-EFFECTS is in an effects loop, the MIX control is most useful in the full
clockwise, "Delay" position.
The FEEDBACK control determines the number of repeats produced at longer time delays
and the spaciousness of reverberant sounds at shorter echo settings. With the FEEDBACK
control set at "0" and delay time over 100ms, a single distinct repeat will be produced. As the
FEEDBACK control is turned clockwise, additional repeats are produced. In addition, with the
control at "10" with 1024ms of delay, numerous passages can be layered then transferred
into REPEAT HOLD for a non-deteriorating background rhythm pattern.
The Delay MULTIPLIER control allows continuous 0.25X to 1X adjustment of the delay time
selected from any one of the interlocking Delay Range PUSHBUTTONS.
The LED RATE Indicator is a simple but effective realtime method of displaying the delay
time. The RATE Indicator flashes at a rate equal to the delay time interval. As
the delay time is increased, the "blink" rate slows. In PA use, a soundman can quickly and
accurately set the repeat echo rate by matching the "blink" rate to the rhythmic pulse of the
music.
