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.

An expander attenuates signals below a specified THRESHOLD by a specified RATIO.

–54 to 0 (55 points)

This determines the level of input signal required to trigger the compressor.

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.

0–120 (121 points)

This determines how soon the signal will be compressed once the compressor has 
been triggered.

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.

0.0 to +18.0 (181 points)

This sets the compressor’s output signal level.

Hard, 1–5 (6 points)

This determines how compression is applied at the threshold. For higher knee set-
tings, compression is applied gradually as the signal exceeds the specified threshold, 
creating a more natural sound.

–54 to 0 (55 points) 

This determines the level of input signal required to trigger the expander.

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 expansion.

0–120 (121 points)

This determines how soon the expander returns to its normal gain once the trigger 
signal level exceeds the threshold.

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.

0.0 to +18.0 (181 points)

This sets the expander’s output signal level.

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, creat-
ing a more natural sound.
