General Description
A cure for compression confusion is here. Quit guessing and anguishing over proper compressor and gate settings. Get on with
what is important, your work. Rane has created a compressor
gate using high quality log rms detectors and Voltage Controlled
Ampliers (VCAs). e DC 22S combines quality compression and gate functions with simplicity. No more compression
headache!
Lets start with what a compressor actually does. No matter
how you cut it, this is an automatic volume control... a hand on
a control, turning it down and turning it up again. e hand is
fast and accurate, but it is just turning a volume control.
When the input signal reaches a level set by the reshold
control, the compressor begins to turn the signal down by an
amount determined by the Ratio control. e DC 22S, like most
compressors, operates by making the loud signals quieter, but
does not make the quiet parts louder. However, by keeping the
loud signals under control, the entire system may be turned up
when necessary to make the quiet parts louder.

ere is more than just a stereo compressor working here.
e adjustable Gate is a downward expander, acting like a compressor running in reverse, making the quiet parts quieter. is
is valuable in reducing system background noise. e Ratio is
xed at 2:1. When the signal drops below the set reshold, the
Gate reshold indicator lights and the output level is reduced
by 2 dB for every 1 dB the input signal level drops.
When using the DC 22S as a true stereo processor with left
and right signals, activate the Link switch. In Link mode, channel 1 becomes the Master and channel 2 the Slave. Gate reshold, Compression reshold, Compression Ratio and Output
Level are all controlled by channel 1. is ensures that both
channels track perfectly, maintaining perfect balance and image.
e channels are totally independent with the Link switch o.
e DC 22S oers performance and simplicity not found
(until now) in this price range. Designed for the working musician or club system, e DC 22S provides reduced complexity
without compromise in audio quality or dependability.
