Section 3. Using effects
INPUT (IN)
This divides the original sound into three
frequency ranges: low, mid, and high.
Gain
Sets the overall volume level before the signal
passes through the compressor.
Dly Time
This sets the amount of time by which the source
input sound is delayed.
SplitL
This sets the frequency (in the lower range) at
which the source sound is split into three
separate ranges.
SplitH
This sets the frequency (in the upper range) at
which the source sound is split into three
separate ranges.
LIMITER (LIM)
This suppresses high-level signals to prevent
distortion.
On/Off
Sets the limiter to ON or OFF.
Threshold
Adjust this parameter to match the signal.
Limiting will be applied to input levels in excess
of this level.
Attack
This sets the time it takes for the limiter to go into
effect once the input level exceeds the threshold
level.
Release
Adjusts the time until when the limiter will turn
off after the input level falls below the threshold
level.

MIXER (MIX)
Adjusts the volume of each frequency band.
Lo Level
Sets the volume level of the lower range after the
signal passes through the compressor.
Mid Level
Sets the volume level of the midrange after the
signal passes through the compressor.
Hi Level
Sets the volume level of the upper range after the
signal passes through the compressor.
NOISE SUPPRESSR (NS)
This effect reduces the noise and hum. Since it
suppresses the noise in synchronization with the
envelope of the sound (the way in which the
sound decays over time), it has very little effect
on the sound, and does not harm the natural
character of the sound.
On/Off
This parameter turns the noise suppressor effect
on/off.
Threshold
Adjust this parameter as appropriate for the
volume of the noise. If the noise level is high, a
higher setting is appropriate. If the noise level is
low, a lower setting is appropriate. Adjust this
value until the decay of the sound is as natural as
possible.
* High settings for the Threshold parameter may result in
there being no sound when you play with your
instruments volume turned down.
Release
Adjusts the time from when the noise suppressor
begins to function until volume reaches "0."
OUTPUT (OUT)
This makes settings that affect the overall output.
Level
Sets the volume level of the overall sound after
the signal passes through the limiter.
