When the DETECT LIMIT LED (reference (10)) flashes, the maximum gain reduction will be 32dB. (4) ATTACK The signal level of the compressor is controlled by an internal VCA (Voltage Control Amplifier). The response time of that VCA is determined by this rotary control, which is continuously variable from 0.2 through 20 msec. (5) RELEASE The amount of time it takes the control circuit to recover from processing and return to unity gain is determined by setting this continuously variable rotary
