RELEASE
It’s an 11 position selector. Timing indications indicate the first time constant (63%
of final value) of the time the compression action ceases. It is expressed in seconds.
THRESHOLD
This potentiometer (or 24-step rotary switch for the mastering version) indicates at
which level the peak reduction action starts. In full ccw position the compression is
out. At cw position the compression is the max. available.
It depends on the
INPUT selector and the level of the incoming audio signal.
SIDE CHAIN HIGH PASS FILTER
It lets you cut the bass frequencies enter the side chain rectifier, so that the bass notes
are not governing the compression action. It does not affect the actual audio signal
path, just the Peak Reduction action. This switch is effective for bass-heavy music,
where you don’t want the bass driving the whole action of compression.
BYPASS
Two independently operated switches for each channel, controlling an audio relay
action. In bypass position the output connector is short circuited through the input
connector (Hard-Wired Bypass).
STEREO LINK
It toggles between:
DUAL MONO : the unit acts as two independent channels.
STEREO : the side chains are tied together, this way the stereo image is preserved.
When the switch is on STEREO position, you still have to manually balance, and set
equal, all of the selectors.
You can match them precisely by feeding the unit with a sine wave tone, and set the
levels exactly equal through the meters.
