6.5 Release
Release determines how quickly the compressor returns to normal gain
following a transient over the threshold. The setting of the release time can be
varied from 5ms to 2s, and is very much dependant on program type. The
times printed around the control refer to the approximate time taken for the
signal to be recovered to 90% of from the initial level. The setting of a wrong
speed will result in one of the following conditions:
This control determines how quickly the DPR-422 compressor responds to
signals once the threshold is exceeded and provides a range of times from 50us
to 100ms. For transient signals (very sudden 'spikes' in the signal that last a
short time), a fast attack time is desirable. For other types of program material a
slower time will be more useful. It is always better to start with a slower time,
and progressively speed up the response as necessary, since too fast a time
may cause distortion of the sound, especially with signals that contain a lot of
low frequencies. The times printed around the control refer to the approximate
time taken for the signal to be reduced by two thirds of the ultimate reduction.
