Rolls CL151 GLC User Manual

The plug connected to the Tip is the "Send" which will connect to the Input of the signal
processing device, and the Ring is the "Return" which connects directly to the detector
(compression control) circuit.
Side Chain circuits are often used in "ducking". Ducking is momentarily lowering one sig-
nal under another signal. For example, you may wish to automatically lower a music signal
under a paging microphone signal, then have the music return to normal level after the
page is over. This would be accomplished by running the music into the compressor, and
having the page signal connect into the Side Chain return. The page signal must also be
connected to the main mixer or amplifier as well. When the paging signal begins, its signal
goes to the main mixer and the Side Chain circuitry. The music is compressed or "ducked"
under the page.
