Table 15: Knee options
Knee mode Description
Hard knee Compressor immediately applies gain reduction at selected
ratio once attack time has elapsed.
Medium knee Intermediate knee type.
Soft knee Compressor, starting from slightly before threshold, gradually
makes the transition to applying gain reduction at selected
ratio.
1
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.)
2
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 273.
3
Quick access button, selects the local
input channel and assigns the all of the
compressor controls to the input channel strip
(and the channel’s compressor processing area
to the GUI channel strip) for near instant
access.
4
threshold control knob, sets the signal
level above which gain reduction starts to be
applied. Range is from -50dB to +25dB
(+20dB in Func. Spec.).
5
comp/gate up and down select buttons,
for swapping dynamic section control from
compressor to gate, and vice versa.
6
Compressor make up gain control knob,
compensates for the reduced loudness of a
compressed signal. Range is from 0dB to
24dB.
7
Compressor KNEE switch, controls how
compressor starts to apply gain as the signal
goes through the threshold; see “Compressor
graph” on page 270. For a description of the
options, see Table 15 below. For more
information, see “Knee” on page 312.
8
Compressor ratio/range/[ratio] control
knob, adjusts amount of compression applied
to signals above threshold. Range is from
infinity (
∞ ) to 1:1. When set to maximum
(1:1), sets compressor to limiter mode.
9
Compressor attack control knob, adjusts
time for compressor to respond after an over-
threshold signal. Range is from 0.2ms to 20ms
(milliseconds).
10
MODE switch, selects compressor mode.
There are four compressor types available:
corrective, adaptive, creative and vintage.
See “PRO6 compressor modes (dynamic)” on
page 311 for details.
11
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).
12
Compressor ‘gain reduction’ meter (just
above the graph), mimics the gain reduction
meter at the top of the input channel’s fast
strip (see “Input metering” on page 260).
