User Interface
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 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 control is continuously vari-
able from +20 dB to –40 dB.
Meter Select
Select what the VU meter should display:
Input: The meter shows the input level.
Compression: The VU meter is showing the gain reduction.
Output: The meter shows the output level.
Please note that it does not show peak or true RMS, it is a VU meter and behaves just
like the original unit.
The meter and the plug in is calibrated so that a sine wave showing 0 VU at the output corresponds to a –18 dBFS output signal.
Correspondingly, a 18 dBFS sine at the input will show 0 VU if the meter is set at showing the input signal.
