are three horizontal rows of buttons for the attack, release and ratio. Simply tap the button you desire
for the attack, release and ratio. The current selection will illuminate green. The threshold and gain
settings (but not the attack, release and ratio settings) may also be manually entered via the current
parameter display. The compressor may be adjusted whether the compressor is on or o.
Threshold — Threshold sets the threshold of the compressor in dB below 0 dBFS.
The range of the threshold setting varies from –80 dBFS to 0 dBFS.
Gain — Gain adds make-up gain to the output of the compressor. This is useful to make the
apparent volume of the signal the same with the compressor in and out of the signal chain.
The range of the make-up gain varies from 0 dB to 20 dB.
Attack — Attackdetermineshowquicklythecompressorreactsoncethesignalisabovethreshold.
Short attack times allow compressing on short transients, while longer attack times cause these

input level, amount of gain reduction or output level. The input and output meters range from
–20 dBu to 0 dBu. The reduction meter ranges from 0 to 20 dB. Mono metering is displayed for inputs
and outputs on unlinked auxes and stereo metering is displayed for inputs and outputs on linked auxes.
