Compressor
When the input volume exceeds the THRESHOLD level, the input
volume is compressed, reducing output volume variation.
For example, by reducing the levels of loud sounds, lower level
sounds become relatively louder, creating a more even volume
level throughout and a more sustained sound.
On the COMPRESSOR page, three meters show the level of the
signal input to the compressor (INPUT), the level of the signal
output from the compressor (OUTPUT) and the gain reduction
caused by the compressor (GR).
THRESHOLD knob
Sets the threshold level that will cause the effect to start.
Range: −32 dB–0 dB (default: −12 dB)
RATIO knob
Sets the compression ratio for the input volume.
Turning it right raises the compression ratio, increasing
the amount of compression.
Range: 1.0:1–inf:1 (default: 2.0:1)
ATTACK knob
Sets the amount of time until the compression reaches
the compression RATIO setting after the input volume
exceeds the threshold level.
Range: 2 ms–200 ms (default: 20 ms)
RELEASE knob
Sets the amount of time until the compression stops and
the sound returns to its uncompressed level after the
input sound goes below the threshold level.
Range: 10 ms–1000 ms (default: 420 ms)
GAIN knob
Sets the gain of the output signal.
When the volume is compressed, the output level
becomes lower than the input level. Use the GAIN knob
to increase the output level so that it is close to the input
level.
Range: 0 dB–32 dB (default: 4 dB)
NOTE
• If the input is a stereo signal (stereo-linked channel or
master), compression will start and be applied to both
channels when either the left or right input channel exceeds
the threshold level.
• When the compressor is off, the compressor curve will
appear but the meters will not be active.

Noise Suppressor
When the input volume becomes less than the threshold level,
the output level is reduced automatically to suppress noise.
When the threshold level is exceeded, the sound is output at its
ordinary level again.
This is useful for reducing noise during performances and
pauses in sound input.
THRESHOLD knob
Sets the threshold level that will cause the effect to start/
stop.
Range: −84 dB to −24 dB (default: −64 dB)
SUPPRESSION knob
Sets the amount the output level will be reduced when
the input sound becomes less than the threshold level.
The higher the value, the more the output level and
noise will be reduced.
Range: 12 dB to 72 dB (default: 42 dB)
ATTACK knob
Sets the amount of time until the set suppression
amount is reached after the input sound goes below the
threshold level.
Range: 0 ms–4000 ms (default: 5 ms)
RELEASE knob
Sets the amount of time until suppression stops after the
input sound exceeds the threshold level.
Range: 0 ms–4000 ms (default: 320 ms)
NOTE
If the input is a stereo signal (stereo-linked channel or
master), noise suppression will start when both the left and
right input channels go below the threshold level.
