The Effects
30
RATIO -
Sets the gain reduction ratio. This is the ratio of input power to output power beyond the
threshold. For example, if the threshold is -40 dB, the input signal is -30 dB and the ratio is 2.0 the
output will be -35 dB.
ATT -
Attack rate. Sets how fast the compressor reduces its gain once the threshold is exceeded.
Higher values equal faster response.
REL -
Release rate. Sets how fast the compressor restores the gain once the signal has fallen below
the threshold.
LEVEL -
Sets the output level of the band.
DET -
Selects the type of detector to use, RMS or Peak.
MUTE -
Mutes the output of the band. You can use the mute controls to audition one or more bands.
Filter
The Filter module is a simple programmable filter designed for general tone shaping. It allows a
variety of different filters along with real-time control of the filter parameters. You can use the Filter
module for quick, static tone shaping or for elaborate, dynamic tone manipulation.
It can be used as a straight gain block by setting the filter type to NULL. Another possibility is to
use it as a treble booster (with more programmability than the one in the Drive module).
In the 60's guitarists began experimenting with booster pedals to increase the signal level into their
amplifiers. This increased the amount of distortion their amps would produce. The more popular
booster pedals had extra treble boost in addition to overall boost. This technique was essential to
Brian May's tone on the early Queen recordings where a treble booster into a Vox AC-30 gave that
unmistakable sound.
To use the Filter/Boost module as a treble booster set the
TYPE
to either
HIGHPASS
or
BANDPASS
.
Experiment with the
Q
and
FREQ
controls to achieved the desired effect. Increase the level to
increase the overall signal level out of the block.
The
FREQ, Q, GAIN, LEVEL
and
PAN
parameters are all controllable. To attach a modifier to these
parameters select the parameter and press
ENTER
. This brings up the
MODIFIER
menu. When any
of these parameters are attached to a modifier an asterisk (*) appears after the name indicating such.
Parameters
TYPE -
Sets the type of filter. All the standard filter types are available. A
NULL
type has a flat
frequency response characteristic.
FREQ -
Sets the center frequency of the filter.
ROFFS -
Sets the right channel frequency offset as a multiple of the left channel. A setting of 0.5,
for example, would set the right channel frequency to half the left.
