DIGITAL SIGNAL PROCESSOR
The Input Gate feature allows signals above a certain level to pass
and attenuates lower level signals. When 'open', the Input Gate
passes the input signal un-attenuated. When 'closed', it attenuates
the input signal by an amount specified with the Depth control.
There are eight parameters which control this feature:
Enable Gate
Switches the gate on or off.
Depth
Sets the 'closed' gain of the Gate.
Control range is from -100dB to 0dB in 0.5dB steps
Static Threshold
Specifies the peak signal level (after side-chain processing) above
which the gate will open.
Control range is from -80 to +20dB in 0.5dB steps
Hysteresis
Sets a range in dB above and below the Threshold which separates
the levels at which the Input Gate opens and closes. The input
signal must reach a level above the Threshold plus Hysteresis to
