■ COMPRESSOR
The COMP processor attenuates signals above a specified THRESHOLD by a specified RATIO. The
COMP processor can also be used as a limiter, which, with a RATIO of ∞:1, reduces the level to the
threshold. This means that the limiter’s output level never actually exceeds the threshold.
■ EXPANDER
An expander attenuates signals below a specified THRESHOLD by a specified RATIO.
Parameter Range Description
THRESHOLD (dB) –54 to 0 (55 points)
This determines the level of input signal required to
trigger the compressor.
RATIO
1.0:1, 1.1:1, 1.3:1, 1.5:1, 1.7:1, 2.0:1,
2.5:1, 3.0:1, 3.5:1, 4.0:1, 5.0:1, 6.0:1,
8.0:1, 10:1, 20:1, ∞:1 (16 points)
This determines the amount of compression, that is,
the change in output signal level relative to change
in input signal level.
ATTACK (ms) 0–120 (121 points)
This determines how soon the signal will be
compressed once the compressor has been
triggered.
RELEASE (ms)
44.1kHz: 6 ms – 46.0 sec
48kHz: 5 ms – 42.3 sec (160 points)
This determines how soon the compressor returns to
its normal gain once the trigger signal level drops
below the threshold. The value is expressed as the
duration required for the level to change by 6 dB.
OUT GAIN (dB) 0.0 to +18.0 (181 points) This sets the compressor’s output signal level.
KNEE Hard, 1–5 (6 points)
This determines how compression is applied at the
threshold. For higher knee settings, compression is
applied gradually as the signal exceeds the specified
threshold, creating a more natural sound.

normal gain once the trigger signal level exceeds the
threshold.
RELEASE (ms)
44.1kHz: 6 ms – 46.0 sec
48kHz: 5 ms – 42.3 sec (160 points)
This determines how soon the signal is expanded
once the signal level drops below the threshold. The
value is expressed as the duration required for the
level to change by 6 dB.
OUT GAIN (dB) 0.0 to +18.0 (181 points) This sets the expander’s output signal level.
KNEE Hard, 1–5 (6 points)
This determines how expansion is applied at the
threshold. For higher knee settings, expansion is
applied gradually as the signal falls below the
specified threshold, creating a more natural sound.
