The available range is –25dB to +15dB. A range of –25dB to –65dB is available
when the –40dB switch is engaged (see “Gate/Exp Threshold –40dB”
on page 175).
In typical use it’s best to set the threshold value to just above the noise floor of
the desired signal (so the noise doesn’t pass when the desired signal is not
present), but below the desired signal level (so the signal passes when
present).
Gate/Exp
Threshold
–40dB
The –40dB button increases the sensitivity of the gate and expander
by lowering the range of the available threshold values.
When –40dB mode is active, the threshold range is –25dB to
–65dB. When –40 is inactive, the threshold range is –25dB to
+15dB.
To activate –40dB mode, click the “pull –40” label text or the red indicator
just below the Threshold control. –40dB mode is active when the red indicator
illuminates.
Gate/Exp Range
(RGE)
Range (RGE) controls the difference in gain between the
gated/expanded and non-gated/expanded signal. Higher values
increase the attenuation of signals below the threshold.
When set to zero, no gating or expansion occurs. The available
range is 0dB to –60dB.
Gate/Exp Fast
The Fast mode switch defines the gate/expander attack time,
which is the duration between the input signal reaching the threshold
and processing being applied. Two times are available: 500
microseconds (when Fast is off) and 50 microseconds (when Fast
is active).
To activate Fast mode, click the “pull FAST” label text or the red indicator just
below the Range (RGE) control. Fast mode is active when the red indicator illuminates.
Gate/Exp
Release (REL)
Release sets the amount of time it takes for processing to engage
once the input signal drops below the threshold level. The
available range is 10 milliseconds to 3 seconds.
