3: DESCRIPTIONS OF THE EFFECT PROGRAMS
& THEIR PARAMETERS
THE BALANCE AND OUTPUT
LEVEL PARAMETERS
Since all of the GEP50 effects have the same BALANCE and
OUT LVL (Output Level) parameters, we’ll describe them here
and leave them out of the descriptions of each effect that
follow. BALANCE and OUT LVL are normally the last two para­
meters called in an effect’s parameter list.
Effect/Direct Signal Balance (BALANCE): 0
—
100%
This parameter adjusts the balance between the direct sound
of your instrument (or other source) and the effect signal. At
100% only the effect sound is delivered from the GEP50
outputs, while at 0% only the direct sound is output. At a
setting of 50%, the direct and effect sounds are output in
approximately equal proportions.
Effect Output Level (OUT LVL): 0 — 100%
This parameter sets the output level of the effect. This is
particularly handy for matching the levels between effects
when setting up an effect sequence for a live performance.
The distortion programs are capabie of producing an extremeiy
broad range of distortion sounds that are ideai for virtuaiiy aii
guitar styles. The various presets provide a range of immedi­
ately useful distortion sounds.
Midrange EQ Frequency (MID FRO): 500
—
4,000 Hz
Sets the mid-frequency range to be boosted or cut using the
next parameter; MID GAIN.
Midrange EQ Gain (MID GAIN): -12 — +12 dB
Boosts or cuts response in the frequency range set by the
MID FRQ parameter (above). A setting of 0 produces no
boost or cut. Minus settings (e.g: -6 dB) cut response in the
selected frequency range, while plus settings (e.g: +12 dB)
boost response.
Bass Boost/Cut (BASS): -12
—
+12 dB
Permits boosting or cutting the low-frequency range. Minus
settings (e.g: -6 dB) reduce the low-frequency content of the
sound, while plus settings (e.g: +6 dB) emphasize the low-
frequencies.
Trigger Level (TRG. LEVEL): 1 — 100
Determines the amplitude of the input signal required to
trigger the distortion effect. This parameter, in conjunction
with the RELEASE parameter below, functions effectively as
a noise gate to cut- out hiss and noise when an input signal
is not present. TRG LEVEL should be set so that the effect
is activated only when a note is played on the instrument
used.
Release Time (RELEASE): 5
—
32000 milliseconds
Determines the amount of time it takes for the distortion
gate to close after the input signal drops below the trigger
level. Proper setting of the RELEASE parameter is essential
to allow a natural decay of the source instrument sound.
Distortion (DISTORTION): 0 — 100%
This parameter sets the "degree” of distortion produced. A
setting of 0 produces a perfectly clean sound, while a setting
of 100 produces the most heavily distorted sound.
Treble Boost/Cut (TREBLE): -12 —+12 dB
Permits boosting or cutting the high-frequency range. Minus
settings (e.g: -6 dB) reduce the high-frequency content of the
sound, while plus settings (e.g: +6 dB) emphasize the high-
frequencies.
