Edit/Effect Parameters
39
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 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.

ROM-44 KEYED EXPNDR
KEYED EXPNDR operation is identical to the Expander. The only difference is that the left signal
(BUS1 or BUS2 hard left) is expanded as determined by the key. The key is the right channel
signal (BUS1 or BUS2 hard right). Make sure your sources are routed this way in order for this
effect to work properly. BUS3 is a dry path.

EXPANSION RATIO
Range:
1/1 to 1/40, INF
This parameter sets the amount of expansion. The range is based on decibels (dB) below the
threshold. If this is set to 1/4 for example, it will expand changes in signals below the threshold
by a factor of four. When this is set to infinity, it acts as a gate. A setting of 1/1 offers no
expansion.
