Description
Compressor KNEE switch, controls how compressor starts to apply gain as
the signal goes through the threshold (see "About the compressor graph"
on page 252). There are three knee types as follows, accompanied by their
typical affects on the compressor graph:
• Hard knee Compressor immediately applies gain
reduction at selected ratio once attack time has elapsed.
This knee has hardly any curve at all.
• Medium knee Intermediate knee type.
• Soft knee Compressor, starting from slightly before
threshold, gradually makes the transition to applying gain
reduction at selected ratio. This knee is noticeably more
rounded.
For application notes, see "Knee" on page 290.
Quick access button, which directly selects the compressor or gate detail
areas on the input channel strip.
To aid set up, the compressor has a side chain listen that sends the side
chain onto a solo bus. This side chain listen LED indicator illuminates to
warn you that soloed material is from the side chain, and not the main
channel. For information on the side chain, see "Side chain" on page 255.
ON switch, enables the compressor in the signal path. When switched off,
compressor is bypassed. (Both the comp and gate switches can be on at
the same time.)
Compressor attack control knob, adjusts time for compressor to respond
after an over-threshold signal. Range is from 0.2ms to 20ms
(milliseconds).
MODE switch, selects compressor mode. There are four compressor types
available: corrective, adaptive, creative and vintage. See "PRO2
compressor modes (dynamic)" on page 289 for details.
Compressor release control knob, adjusts time for compressor to recover
after programme material falls back below threshold. Range is from 0.05s
to 3.00s (seconds).
threshold control knob, sets the signal level above which gain reduction
starts to be applied. Range is from -50dB to +25dB.
Compressor 'gain reduction' meter.
