4.7.2 Input Compressor

To open the Input Compressor window (Figure 4.8), select its icon (shown
above) in any channel in the Signal Path window.
The input compressor provides a means for controlling the dynamic range of
input signals. It is a feed-forward type, which performs the compression after the
Input Level Meter. The Input Compressor's effect on input gain is metered by the
Input Dynamic Cut/Boost Meter.

Seven parameters control this feature:
1. On/Off
Turns this feature on or off.
2. Compression Ratio
Determines how many dB the input level must change for a 1 dB change in out-
put level. Dynamic variations in the input signal will be reduced by a factor equal
1
to the compression ratio. Control range is 2:1 to 32:1.
3. Threshold
Specifies the average signal level (after side-chain processing) above which the
compressor will begin to reduce gain. Control range is from –80 to +20dB in 1
dB steps.
4. Soft Knee (Width)
Sets a range in dB around the actual threshold through which the compressor
gain is gradually modified from unity to the final compressed gain. Control range
is from 0 dB to +20 dB in 0.5 dB steps.

5. Attack Time
4
Sets the time required for the Compressor to decrease its gain by 20 dB. Control
range is from 1.0 to 100 milliseconds in 1 millisecond increments.
6. Release Time
5
Sets the time required for the Compressor to increase its gain by 20 dB. Control
range is from 0.1 to 10 seconds in 10 millisecond increments.
