Detailed Parameters
Limiter On/Off
Turns the Limiter module on and off.
OverEasy (O) Off to 10
OverEasy is a soft-knee smoothing function that occurs about the limiting threshold. OverEasy
off is considered hard knee; the higher the OverEasy, the greater the smoothing.
Threshold -40 to +20dBu
Threshold is the signal level at which the unit starts to limit the signal. If the level is set to -10
dBu, any signal larger than -10 dBu is limited while any signal that has a level that is lower than
-10dBu is left at the same signal level. Light limiting is where only the loudest parts of the sig-
nal go over the threshold. Very heavy limiting can be achieved by setting the threshold low
enough that almost the entire signal content is over the threshold. For most signals, the most
natural compression is achieved when most of the signal content remains just below the thresh-
old and only the peaks cross the threshold.
Auto On/Off
When auto is turned on the ZonePro™ will continuously set the attack / hold / release controls itself.
Attack .01 to 200 m Sec (per band or global)
.
This is the speed at which the limiter starts to limit the signal once it has crossed the threshold
Hold 0 to 500 m Sec (per band or global)
Hold is the time the limiter stays in gain reduction after the signal level has dropped below
threshold. Hold is useful when you want the limiter to function for a period of time after it has
been triggered. Be careful not to set the hold time too long as it will not release in time.
Release 360 to 5 dB / Sec (per band or global)
Just like the release time on the compressor, the limiter's release time controls how fast the lim-
iter releases from gain reduction after the signal drops below the threshold. Set the release times
longer for lower frequency bands and shorter for higher frequency bands.
