T HRESHOLD CONTROL
The “Thres” knob controls the level at which the compressor
begins to reduce the gain applied to the signal. When the
detector level is below the threshold level, no gain reduction
is applied. As the detector level increases above the thresh-
old level, the gain is reduced as indicated by the knee dia-
gram associated with the compressor. The compressor knee
is soft. The ratio increases as the difference between the
detector level and the threshold increases.
The compressor threshold level is also indicated by the green
arrow above the gate input meter. You can adjust the thresh-
old level using this indicator as well as by using the “Thres”
knob.
R ATIO C ONTROL
The “Ratio” knob controls the ‘terminal’ ratio used to com-
pute the gain reduction of the compressor. When the ratio
associated with the soft knee hits the ratio specified by the
ratio knob, the knee ‘hardens’ and remains at the same con-
stant ratio. If you set the ratio to 1000:1 the compressor will
have a soft knee for all input levels and thresholds. This
makes the compressor work like a classic all tube limiter/
compressor.
A TTACK CONTROL
The “Attack” knob allows you to adjust how quickly the gain
reduction is increases when the detector level goes above
