Generally, a hard-knee compressor will sound louder, more aggressive, and more audible when compressing. The
softer the knee, the smoother and less noticeable the compression will be. Use proper judgement, depending upon the
application and/or genre of music being reproduced through the sound system and experiment to find the best setting
that works for your application.
• AUTO [OFF, ON]
Turns Auto mode on and off. When turned off, attack, hold, and release times will be determined by the ATTACK, HOLD,
and RELEASE parameters. When turned on, attack, hold, and release times will be program-dependent, meaning they
will adjust automatically and dynamically based on input signal characteristics. Note that when AUTO is on, manual
ATTACK, HOLD, and RELEASE settings will be ignored.
• ATTACK [100µs - 200ms]
Sets the speed at which the compressor starts to reduce the signal level once it has exceeded threshold. When AUTO is
on, this parameter is ignored and set dynamically.
• HOLD [0s - 500ms]
Sets a timer which starts when the signal falls back below threshold and, once the time has elapsed, allows the
compressor to release, thereby preventing the compressor from releasing prematurely. When AUTO is on, this parameter
is ignored and set dynamically.
• RELEASE [360dB/s - 5dB/s]
Sets the rate at which the compressor will come out of gain reduction once the signal level drops back below threshold
and the hold time has elapsed. The release time 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. When AUTO is on, this parameter is ignored and set dynamically.
