CONTROLS:
GAIN:
The gain control is used to "adjust" for the gain
loss which takes place when the unit is compres-
sing. It is placed before the inputtransformer.
The gain-control is continuously variable from
-6 dB to +20 dB.
DISPLAY:
The green LED display shows the gainreduction for
both the compressor and for the limiter. A red LED
show if the limiter is active.
The display is from the factory supplied in dotmode.
This can be altered to a bar by placing a strap on
U6 (U106) from pin 3 to pin 9
LINK SWITCH:
Interconnects several compressors on linkbus 1 or
linkbus 2.
If the compressor is left in the off position, it
works entirely independently.
IN/BYPASS:
This switch switches the compressor in and out of
the signal path. In the bypass position the entire
unit is switch out.
COMPRESSOR:
RATIO:
The ratio control varies the ratio by which the
input signal is compressed.
If the ratio selected is to 2:1, and the input
signal increases 10 dB, the output signal is only
increased by 5 db.The ratio control is continuously
variable from 1,6:1 to 20:1.
THRESHOLD:
The threshold is the point where the compressor
begins its action. It is defined as the point where
the gain is reduced by 1 dB.
The threshold is related to the output level and is
continuously variable from off to -10 dBm.
ATTACK:
The attack control chooses how fast/slow the com-
pressor responds to an increase in the input signal.
The attack control is continuously variable from 0.3
to 10 milliseconds.
RELEASE:
The release control chooses how fast/slow the com-
pressor responds to a decrease in the input signal.
The release control is continuously variable from
0,07 to 2 seconds.
