Edit/Effect Parameters
THRESHOLD
Range:
-96 to +0 dB
This parameter sets the threshold level. Signals that exceed this level will be unaffected, while
signals that are below will be expanded. To turn off the expander, set the level to -96 dB.
ATTACK TIME
Range:
50µs to 100ms
This parameter determines the attack rate after the initial signal has been detected and before the
expansion takes affect.
RELEASE TIME
Range:
1ms to 10.0s
This parameter determines the release rate after the signal has been detected below the threshold
level. This is generally chosen longer than the attack time.
HOLD TIME
Range:
1ms to 10.0s
This parameter is the detection sustain time in the ADSR which constitutes attack, sustain, and
release.
EQ GAIN
Range:
-48 to +48 dB
This parameter controls the amount of boost applied to the output signal of the high/low pass
filter. This accounts for insertion loss through those filters.
HIGH PASS FC
Range:
4 to 8000 Hz
This parameter sets the cutoff frequency of the lower frequency band high pass shelving filter.
LOW PASS FC
Range:
100 Hz to 15 KHz
This parameter sets the amount of boost or cut applied to the low pass filter.
TRIGGER MASK
Range:
OFF or ON
This parameter enables the trigger mask function. Once triggered, the side chain detector will see
no input signal for a duration specified by the TRIGGER TIME.
TRIGGER TIME
Range:
1ms to 10.0s
This parameter sets the duration over which the side chain detector will be blacked out. This
parameter is useful for isolating the first bar of a drum track.
MASK THRESHOLD
Range:
-96 to +0 dB
This parameter sets the trigger mask threshold level. Signals that fall below this level will trigger
the mask function. The trigger mask function uses the (expander) THRESHOLD as upward
hysteresis. Therefore, the MASK THRESHOLD should always be set lower than the (expander)
THRESHOLD.
OUTPUT MIX
Range:
0 to 99
This parameter mixes the output of the left signal with the output of the right signal. This is the
output mixer that is shown in the diagram.
OUTPUT GAIN
Range: -48 to +48 dB
This parameter sets the amount of cut (negative values) or boost (positive values) applied to the
expander on the output volume. We recommend a starting application of +0 dB.
