CONTROLS:
GAIN:
The gain control is used to "make up" for the gain loss, which takes
place when the unit is compressing. It is placed after the gain-reduction
circuit and therefore has no influence on the threshold setting. The
gain-control is continuously variable from off to +30 dB.
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 2:1 to 10:1.
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 continuously variable from +20dBU to -40 dBU.
METER:
The LED VU-display switch has two positions:
1. Compression
The VU-display is reading gain reduction. Its rest
position is "0 VU", and the amount of compression is
shown as a decreasing deflection in dB.
2. Output
The VU-meter is reading the level at the output
socket.
"0 VU" is equivalent to +4 dBU.
IN/OUT:
This leverswitch switches the compressor in and out of the signal path.
The out position bypasses the compressor section, but the amplifier
remains in the signal path.
ATTACK:
The attack control chooses how fast/slow the compressor responds to
an increase in the input signal.
The attack control is continuously variable from 0.5 to 300 milliseconds.
RELEASE:
The release control chooses how fast/slow the compressor responds to
a decrease in the input signal.
The release control is continuously variable from 0,05 to 10 seconds.
