CONTROL DESCRIPTION
Threshold:
Determines the input level above which gain reduction will be applied and may be
set in the range -30dB to infinity. Because the compression system is based on
the Soft Knee principle, the onset of compression is progressive, so no Ratio
control is necessary.
Big:
Makes the compressor side chain less sensitive to low bass frequencies, so
reducing the ducking effect caused by bass energy and effectively boosting the
bass output
, the 'Bigger' option more so.
Attack:
Six switchable Attack settings are provided giving various settings. The actual
attack time is further modified by the release setting chosen
Attack Times: 1 2 ms
2 8 msec
3 15 msec
4 25 msec
5 30 msec
6 50 msec
Release:
There are three fixed Release times and a further three which are programme
dependent. Switch settings 1 through to 3 provide progressively increasing
release times, while positions 4, 5 and 6 cause the release times to vary in a
manner which automatically adapts to the dynamics of the incoming signal, as
detailed below.
Release Times 1 100 ms (Fixed)
2 500 msec (Fixed)
3 1 sec (Fixed)
4 Semi-Auto 200 ms to 2 sec Signal dependent
5 Semi-Auto 500 ms to 5 sec signal dependent
