The Setup Button
f EQ PARA WIDTH
Defines how narrow or wide the parametric
band is to be. The ends of the control range are
labelled “NARROW” and “WIDE” to add mean-
ing to the numbers in the middle of the control
range.
f COMPRESSION THRESH(old)
The THRESHOLD and RATIO controls work to-
gether to offer simple audio compression of the
guitar signal. The default settings offer very gentle
compression of peaks.
The COMPRESSION THRESHOLD control
sets the level at and above which the amount of
gain reduction (compression) specified by the
COMPRESSION RATIO control will occur. The
range is 0 dB (not compressing any peaks) to -60
dB (compressing everything you play) with the
default being -6 dB.
f COMPRESSION RATIO
This sets how much gain reduction you want
when your guitar level goes above the threshold.
The range is from 1:1 (no gain reduction) to 64:1
(complete flattening of peaks - also known as lim-
iting). The number on the left side of the : (colon)
symbol is how loud your guitar has to be in order
to achieve a 1 dB gain increase. The default setting
is 1.8:1.
Note that the RATIO control has to be set above
1.0 (1.0:1) to apply any compression regardless of
the setting of the THRESHOLD.
Also note that automatic makeup gain occurs
depending on your combination of THRESHOLD
and RATIO. A side effect of compression is that
it can reduce apparent level until makeup gain is
applied to raise the overall level.
overcome room or undesirable guitar resonances.
This smooths the sound and can help overcome
guitar feedback.
The 3 GAIN controls allow +/- 12 dB of adjust-
ment. The 3 FREQ controls range from 20 Hz to
20 kHz.
f EQ LOW GAIN
Boosts or cuts the range of frequencies below
the frequency set by the EQ LOW FREQ control.
f EQ LOW FREQ(uency)
Allows you to define the frequency range for
the low shelf by choosing the highest frequency
below which boosting or cutting is possible.
f EQ HIGH GAIN
Boosts or cuts the range of frequencies above the
frequency set by the EQ LOW FREQ control.
f EQ HIGH FREQ
Defines the frequency range for the high shelf
with the selection of the lowest frequency above
which boosting or cutting is possible.
f EQ PARA GAIN
Boosts or cuts the band of frequencies centered
at the setting of the EQ PARA FREQ control and
its associated EQ PARA WIDTH.
f EQ PARA FREQ
Defines the center of the parametric band.
