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 
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

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

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.
