Bypass (Compressor and Limiter) 
Switch

This toggle switch bypasses the Compressor and 
Peak Limiter. Normally it is used to compare the 
unprocessed signal with the processed signal.

Suggestions for Using the 
Compressor

The fastest way to begin using the Expander is to 
choose one of the presets available in the Librar-
ian menu. (See the 

DigiRack Plug-Ins Guide

 for 

details.)

Alternatively, create your own settings using the 
procedure that follows.

To use the Compressor:

1  

Bypass the Gate or Expander by clicking their 

Bypass toggle.

2  

Turn on Auto Attack & Release.

3  

Turn on Auto Gain Make-up.

4  

Set the Limiter control fully clockwise.

5  

Set the Ratio control. For vocals, try 2.5:1 or 

less. For full mixes use even less. For dynamic 
single tracks, use more.

6  

Adjust the Threshold control until the the ver-

tical VU meter and the Compressor Gain Reduc-
tion (GR) meter show activity. As a rule, the 
Threshold should be 6 dB to 10 dB below the av-
erage input level to hear much change.

Additional Suggestions for Using 
the Compressor

Setting up the Compressor is simpler if the Ex-
pander or Gate is initially set to Bypass and the 
Peak Limiter threshold set to maximum. This 
lets you adjust the Compressor in isolation.

Ratio Amount

The Ratio setting depends on how much the sig-
nal dynamics need controlling. As a rule, higher 
ratios provide a higher degree of control but also 
tend to be more audible in operation when high 
levels of gain reduction are required. The soft-
knee feature of the Compressor makes this far 
less pronounced. Overall, a higher ratio can be 
used than on conventional compressors with-
out compromising the sound quality.

Effective Gain Reduction

If the Attack & Release switch is set to Auto, set-
ting up is simply a matter of adjusting the 
Threshold control until the desired amount of 
gain reduction occurs. You can judge this partly 
by ear and partly by observing the gain reduc-
tion meter. 

A maximum gain reduction of between 8 dB 
and 12 dB is usually adequate. If more gain re-
duction is necessary, consider applying com-
pression during recording and then further 
compression while mixing.

With Auto Gain Make-up disabled, rotate the 
Gain control until as near to 0 dB (full scale) sig-
nal output is seen at the VU meter. For greater 
simplicity, select Auto Gain Make-Up.

Background Noise

Compression during a mix increases the subjec-
tive level of background noises during pauses 
and quiet passages. Unless the noise problem is 
serious, the Expander can attenuate this noise to 
a very high degree, without compromising the 
desired audio signal.
