In/Out When set to ÒInÓ the compressor is active; when set to ÒOutÓ the compressor is bypassed.
Out Gain Compressing the signal causes a reduction in signal level. To compensate, the output gain
parameter may be used to increase the gain by as much as 24 dB. Note that the Out Gain
parameter does not control the signal level when the algorithm is set to ÒOutÓ.
FdbkComprs A switch to set whether the compressor side chain is conÞgured for feed-forward (Out) or
feedback (In).
Signal Dly 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.
CrossoverN The Crossover parameters (1 and 2) set the frequencies which divide the three
compression frequency bands. The two parameters are interchangeable, so either may
contain the higher frequency value.
Atk Low, Mid or High. The time for the compressor to start to cut in when there is an increase
in signal level (attack) above the threshold.
Rel Low, Mid, and High. The time for the compressor to stop compressing when there is a
reduction in signal level (release) from a signal level above the threshold.
Smth Low, Mid, and High. 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.
Ratio Low, Mid, and High. The compression ratio. High ratios are highly compressed; low ratios
are moderately compressed.
Thres Low, Mid, and High. The threshold level in dBFS (decibels relative to full scale) above
which the signal begins to be compressed.
