Detailed Parameters

 

Window fader

This parameter adjusts the amount of variation in the output and ranges from 1 to 10dB. For most applica- tions a Window of +/- 2 or 3 dB maintains the signal adequately.

Attack fader

The Attack fader adjusts how fast the AGC will increase gain after the signal drops below the Target. It ranges from 1 to 9.95 Seconds.

Release fader

This parameter adjusts the AGC rate of gain reduction once the signal is above the Target. It ranges between 10 to 0 dB/Second.

Limiter Threshold fader

The AGC is designed to add or remove gain slowly so that the overall response will sound natural. Because of its slow nature, a fast Limiter has been added to the AGC to protect the system from sudden transients. The Limiter threshold can be set from the top of the AGC Window up to 0dBFS.

Limiter Auto On/Off switch

This button turns Auto mode for the Limiter on and off. Auto mode dynamically sets the Limiter Attack and Release based on the input signal.

Limiter Attack fader

This parameter sets the speed at which the limiter starts to reduce the gain of the input signal once it has crossed the limiter threshold. It ranges from .01 to 200 mSec.

Limiter Release fader

The Limiter Release parameter sets the rate at which the Limiter will go out of gain reduction once the signal drops below the threshold. The Release range is between 360 and 5 dB/Sec. Auto mode deactivates this parameter.
