Appendix
COMP Section
COMP
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.

Range
Description
THRESHOLD (dB)
–54.0 to 0.0 (541 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 com-
pressed once the compressor has been triggered.
RELEASE (ms)
44.1kHz: 6 ms – 46.0 sec
48kHz: 5 ms – 42.3 sec
88.2kHz: 3 ms – 23.0 sec
96kHz: 3 ms – 21.1 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 (180 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 speci-
fied threshold, creating a more natural sound.
