coMPRESSoR
ENAbLE:
Turns the COMPRESSOR effect on or off . Select ACTIVE to turn it on . Select
BYPASSED to turn it off .
INSERT:
Positions the COMPRESSOR effect . Choose PRE to position the effect in the
PRE-EFFECTS section . . Choose POST to position the effect in the POST-EFFECTS
section .
ModE (STUdIo/PEdAL):
Determines the source of the gain detector . In STUDIO
mode, the gain reduction envelope comes from the input (feedforward). In PEDAL
mode the gain reduction envelope comes from the output (feedback).
THRESHoLd (db):
The THRESHOLD determines the level at which the compressor
begins to reduce the gain of the input signal . Signals above the threshold are reduced
by an amount equal to the RATIO (see below).
RATIo:
Determines how much gain reduction is applied to signals that are above
the THRESHOLD. For example, when RATIO is set to 2 then signals above the
THRESHOLD will be reduced by 50%. As RATIO approaches its maximum value the
COMPRESSOR becomes closer to a LIMITER .
LEVEL (db):
Adjusts the output level of the COMPRESSOR block. Higher values of
compression can result in decreased overall volume. The level can be adjusted higher
to compensate for this .
MAKEUP (AUTo/off):
Enables or disables the automatic MAKEUP gain feature .
MAKEUP gain will automatically boost the output level of the COMPRESSOR effect
to compensate for the reduction in amplitude due to the compression effect . Can be
used instead of (or in addition to) manual level compensation.
ATTAcK (milliseconds):
Adjusts the ATTACK time of the COMPRESSOR. This
determines how quickly the gain reduction is applied to the signal after it passes
above the THRESHOLD .
RELEASE (milliseconds):
Adjusts the RELASE time of the COMPRESSOR. This
determines how quickly the gain reduction stops being applied after the input signal
crosses below the THRESHOLD .
dETEcT (PEAK/RMS):
Determines the type of detector being used to DETECT the
input level of the signal . In PEAK mode, the detector responds according to the peak
input signal level. In RMS mode, the detector is taking a “root-mean-square” running
average of the input signal . This means it will not respond quite as quickly to abrupt
changes in signal amplitude .
KNEE (db):
The KNEE determines the width of the transition region between
compression and non-compression . At 0dB, the THRESHOLD is an abrupt transition
(picture two straight lines connecting at different angles). This is called a ”hard-knee”
compressor . As the KNEE is increased the transition becomes more gentle which can
help create a smoother sound. This is called a “soft-knee” compressor. You can adjust
this parameter between both types to suit your taste .
