B.5.1 Gate Parameters
The following section describes the parameters available for noise gates:
• Threshold:
Adjusts the level at which the noise gate opens (audio on). The level is
adjustable from -60 to +10 dB.
• Attack:
Adjusts how quickly the noise gate opens when the Threshold level is
reached. The Attack time is adjustable from 50 µs (microseconds) to 5 seconds.
• Release:
Adjusts how quickly the noise gate closes when the trigger level drops below
the Threshold level. The Release time is adjustable from 1ms (millisecond) to 5
seconds.
NOTE:
The Hold parameter can effect the release time by holding the noise gate open
for a length of time before the release time takes effect.
• Depth:
Controls the amount of attenuation when the noise gate is closed (Off). Depth
is adjustable from -60 to 0 dB.
• Hold:
Adjusts the amount of time that the noise gate will stay open before the Release
time takes effect after the trigger level drops below the Threshold level. The Hold time
is adjustable from 1 ms to 5 seconds.
• Masking:
Adjusts the amount of time that must pass before a gate can be retriggered.
This is useful for minimizing false triggering when the gated sound has a predictable
waveform. The Masking time is adjustable from 1ms to 5 seconds.
• Key:
The
Key
button allows an alternate keying source to be selected for the noise
gate. Another module, an external analog bus or an external switch bus can be
selected. Turn the rotary encoder knob to cycle through all available options.
