Detailed Parameters

Attack fader

The Attack parameter sets how quickly the Limiter starts to reduce the gain of the signal after it passes the Threshold. The Attack can range between 0.1 mSec and 200 mSec. The Attack time is dynamically set while in Auto mode.

Hold fader

The Hold parameter is the time the 4800/4820 continues to reduce gain after the signal has dropped back below the threshold. Hold is adjustable between 0 and 500 mSec and is dynamically set while in Auto mode.

Release fader

The Release parameter is the rate at which the Limiter comes out of gain reduction once the signal is back below the threshold and the Hold time has elapsed. Release is measured in dB per second. For example, if Release is set to 5 dB/Sec, and the signal has 10dB of gain reduction, the release time is 2 Seconds. The Release range is from 360 dB/Sec to 5 dB/Sec. The Release rate is dynamically set while in Auto mode.
