Auto On/Off
When Auto Mode is on, the ZonePro™ automatically sets the Attack, Hold, and Release times
for the signal. The auto mode constantly adjusts these parameters in real time for optimum per-
formance from the unit. You will find that for most applications, not only is using the auto mode
faster and easier but by letting the unit constantly tweak these parameters for you will result in
a better end result.
Attack 0.1 m Sec to 200 m Sec
Attack is how fast the compressor starts to compress the signal after it passes the threshold. Fast
attack is useful when dealing with lots of fast transients. The attack control is not active when
in auto mode.
Hold 0 to 500 m Sec
Hold is the time the ZonePro remains in compression after the signal has dropped below the
threshold. A longer hold time is useful in smoothing out the sound when compressing several
fast peaks that are fairly close together in time. The hold control is not active while in auto
mode.
Release 360 dB / Sec to 5 dB / Sec
Release is how fast the ZonePro comes out of compression. The release is in dB per second.
For example, if release is set to 5 dB /sec, and the signal is at 10dB of gain reduction, the release
time is 2 seconds. Having a release time that is either too fast or too slow for the signal can
result in audible artifacts called pumping or breathing. This can cause volume drops in your sig-
nal that may not be desired. The release control is not active while in auto mode.
