CHANNEL DYNAMICS COMPRESSOR & GATE635
The Compressor section
Compressors reduce dynamic range by evening out the difference between loud and quiet signals. This makes signal
levels easier to balance, and can add punch and sustain to the sound.
The compressor/limiter in Channel Dynamics is a flexible processor which has soft-knee (a gradual, smooth onset of
compression) characteristics but can be switched to peak limiting, where levels above the set threshold are instantly
reduced. The compressor also features automatic make-up gain. The parameters are as follows:
On
D Click the On button to activate the Compressor section.
Peak
D Activate to change the signal detection from RMS to Peak, which results in an instant attack time.
Peak mode is suitable for compression of sounds with fast attacks like drums.
Fast
D Click this to make the compressor react to signals above the set Threshold level in a fixed time of 3 ms for
20 dB gain reduction.
Ratio
D Set the amount of gain reduction applied to the signal above the set Threshold (see below).
Range: 1:1 (no reduction) to Infinite:1
Threshold
D Set the level at which onset of compression should occur.
Signals below the Threshold setting are unaffected, but when the level exceeds the threshold, compression kicks
in. Automatic make-up gain (based on the Ratio and Threshold settings) is applied to compensate for level reduc-
tion caused by compression, to maintain a steady output level.
Range: -52 dB to 0 dB
Release
D Set the time it should take before the compressor lets the sound through unaffected - after the signal level
drops below the set threshold.
Set this to short values for “pumping” compressor effects, or to longer values for a smoother change of the dynam-
ics.
Range: 100 ms to 1000 ms
Compressor Gain Reduction Meter
The LED meter shows the gain reduction applied by the compressor.
