RECOVERY

Attack

This is the time between a signal 6dB above the threshold level being applied, and the output signal falling to within 2dB of its final level. With slower attack settings compression is more dependant on the average signal level, while with faster settings it is more dependant on the peaks. Setting of 2ms, 4ms, 6ms, 8ms and 16ms are available.

Recovery

If a signal 6dB above the threshold has been applied for long enough that the output has reached its steady-state level, recovery is the time taken for it to get to within 2dB of its final level if the input is dropped by 6dB. Recovery compliments the attack control by filtering the control voltage; longer recovery times prevent pumping effects where gain reduction follows the program material too closely. Settings of 100ms, 200ms, 400ms, 800ms, 1.5s and 3s are available.

Gain Reduction Meters

Gain reduction meters are provided post the A/B Bias control and pre the CV Link routing buttons to show the level of attenuation being applied. The meters have 20dB f.s.d.
