Command Protocol Reference Guide
A - 75
Description
This parameter sets the RMS level (in dBFS) of the input signal below which
the gate engages. The level must be below this threshold longer than the gate
hold time (set by dp_gate_hold) before the gate begins to apply a gain change.
dp_exp_attack Expander Attack Time
Description
This parameter sets the amount of time (in milliseconds) it takes the expander
to ramp the gain up to the target gain once the input signal level surpasses the
expander threshold.
dp_exp_decay Expander Decay Time
