ATTACK/RELEASE SELECT:
This switch selects how the compressor reacts to an increase (attack) or
decrease (release) of the input signal.
There are three settings of the switch:
1. Fixed.
Attack time: 1 msec
Release time: 50 msec
2. Manual.
Attack time: from 0.5 msec to 300 msec
Release time: from 0.05 sec to 10 sec
3. Fix/man.
This setting combines the release times of fixed and manual
mode. The attack time is as in the fixed mode.
The fix/man mode always has a fast attack, but it is possible to obtain a release time depending
on the input signal, e.g. get a fast release when the peak disappears, then superseded shortly
thereafter by the release time selected by the release control.
From the time the peak disappears, until the selected release time takes over, is dependent
upon the setting of the attack control.
That is, the attack control changes function from a pure attack control, to a control of delay with
the same time range.
The more CW the attack control is turned, the longer time before the release control
takes over.
The more CCW the attack control is turned, the shorter time before the release control
takes over.
This function is valid only if the time of the peak is shorter than the setting of the attack control.
If the peak of the program is longer than the setting of the attack control, or if the attack control
has reached the full CCW position, it will respond as in the manual mode.
The fix/man mode acts as an automatic release function with a constant fast attack time and
fast release time for short peaks and a longer release times for longer peaks.
This setting is mainly intended for use on program material (overall compression).
BUS SELECT:
Interconnects several compressors on bus 1 or bus 2.
If the compressor is left in the off position, it works entirely independently.
