FdbkComprs
A switch to set whether the compressor side chain is conÞgured for feed-forward (Out)
or feedback (In).
Atk Time
The time for the compressor to start to cut in when there is an increase in signal level
(attack) above the threshold.
Rel Time
The time for the compressor to stop compressing when there is a reduction in signal
level (release) from a signal level above the threshold.
SmoothTime
A lowpass Þlter in the control signal path. It is intended to smooth the output of the
expanderÕs envelope detector. Smoothing will affect the attack or release times when the
smoothing time is longer than one of the other times.
Signal Dly
For the feed-forward setting, Signal Dly is the time in ms by which the input signal
should be delayed with respect to compressor side chain processing (i.e. side chain pre-
delay). This allows the compression to appear to take effect just before the signal
actually rises. For feedback compression, this parameter causes both the side-chain and
main signal path to be delayed together.
Ratio
The compression ratio. High ratios are highly compressed; low ratios are moderately
compressed.
Threshold
The threshold level in dBFS (decibels relative to full scale) above which the signal begins
to be compressed.
MakeUpGain
Provides an additional control of the output gain. The Out Gain and MakeUpGain
controls are additive (in decibels) and together may provide a maximum of 24 dB boost
to offset gain reduction due to compression.
