Limiter

Threshold determines how much limiting will occur. When the input signal ex-

Threshold
ceeds the threshold level, the signal above the threshold is limited. A smaller
value results in more limiting. The available range is from +4 dB to +15 dB,
in 0.5 dB increments.
If the compressor is enabled, the Gain control in the compressor section

In this case, the compressor gain can affect the limiter threshold response.
Recovery (release) is the time it takes for the limiter to stop processing after the
Limiter Recovery
signal drops below the threshold value. The available values (in milliseconds)
are 50, 100, 200, 800, a1, and a2.
The automatic settings (a1 and a2) are program dependant. The value for a1
can be as fast as 40ms, but after a sustained period of high signal level, the
period is ≈1500ms. The value for a2 can be as fast as 150ms, but after a sus-
tained period of high signal level, the period is ≈3000ms.
This toggle switch enables the limiter portion of the plug-in. The limiter has no

effect unless this switch is in the "In" (down) position.
Attack Attack determines how fast limiting will engage when the signal exceeds the
limiter threshold. The Fast setting is 2 milliseconds, and the Slow setting is 4
milliseconds.
