6.7.1 Compressor

Figure 6-15 COMPRESSOR Touchscreen

The 

IN/OUT

 meters show the levels coming in/out 

of the compressor. The inverted 

REDUCTION

 meter 

displays the compressor’s gain reduction. 

The graph summarizes the compressor’s parameter 

settings. 

Threshold 

The 

THRESH

 control adjusts the level above which 

attenuation begins. It is adjustable in the range -60 to 

0 dBFS in increments of 0.1 dBFS; the default value is 

0 dB. 

Ratio 

The 

RATIO

 control sets the rate of gain reduction ap-

plied to the signal as it exceeds the threshold. The ratio 

can vary between gentle compression and peak limiting. 

The ratio range is 1:1 (no gain reduction) to the maxi-

mum of 

∞

:1 (peak limiting). The default setting is 1:1. 

Attack 

The 

ATK

 control varies the time the compressor takes 

to begin gain reduction after the signal exceeds the 

threshold. The 

ATK

 time range is 1–300 ms and the in-

crements are scaled such that the faster attack settings 

have finer adjustments. The default setting is 15 ms. 

Release 

The 

REL

 controls the time the compressor takes to 

stop applying gain reduction after the signal decreases 

below the threshold. The 

REL

 time range is 50 ms to 3 

s. The default setting is 200 ms. 

REL

 is scaled such that 

the faster release settings have finer adjustments. 

Gain 

The 

GAIN

 control sets the gain applied to the signal 

after the compressor. This allows 

makeup

 gain to com-

pensate for the compressor’s level reduction. The 

GAIN

range is 0–20 dB in increments of 0.1 dB. The default 

setting is 0 dB. 

Hard/Soft Knee 

The 

HARD/SOFT KNEE

 switch toggles the compres-

sor knee characteristic. It is accessible only from the 

COMPRESSOR Touchscreen (not from DYNAMICS). 

HARD KNEE:

  As the signal exceeds the threshold, gain 

reduction is immediately applied at the full ratio 

setting. 

SOFT KNEE:

  As the signal approaches the threshold, 

gain reduction is gradually applied up to the full 

ratio setting.
