Rel
Release time for the compressor: determines how quickly the compressor restores its normal gain after the
signal goes below the threshold.
Ratio
Sets the amount of compression for the signal. This parameter determines the input/output ratio for signals
above the threshold: for example, a 5:1 ratio means that a signal exceeding the threshold by 5 dB will be
compressed to 1 dB above the threshold.
This parameter is not available in “Limiter Mode”.
Knee
This parameter controls the transition from the uncompressed zone to the compressed zone of the dynamic
curve.
Knee works with Ratio parameter to “gently” reduce the dynamic of the signal reducing the effects of non-
natural sound that a hard compression causes, especially for higher ratios where the changeover from
uncompressed and compressed signal is more noticeable.
Hard knee: basic hard transition of the dynamic curve.
Soft1 knee: smooth and continuous transition of the dynamic curve from 5dB below the threshold to 5dB
above the threshold.
Soft2 knee: smooth and continuous transition of the dynamic curve from 10dB below the threshold to 10dB
above the threshold.
The parameter is not available in “Limiter Mode”.
Gain
Gain control lets you compensate the overall level reduction of a compressed signal.
The parameter is not available in “Limiter Mode”.
Reduction Meter
LED meter to check when and how much the compressor/limiter is reducing the audio. It works only when
compressor is enabled (“ON”).
