so is of limited usefulness. In compressors which use more than 1 PAU, the delay affects the main signal
only, regardless of the side chain conÞguration.
A meter is provided to display the amount of gain reduction that is applied to the signal as a result of
compression.

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).
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 for limited beneÞt.
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.
In/Out In or Out Out Gain Off, -79.0 to 24.0 dB
