INPUT LEVEL indicators: With signal applied, the +4 dBu
LED may light occasionally. If the OL (overload) LED flashes,
turn the output level down on the previous device.
GATE THRESHOLD control sets the point at which the Input
signal level causes the Gate to become active.
_____________________________________________
COMPRESSOR THRESHOLD control sets the point at
which the Input signal level causes the Compressor to become
active. See Figure 1 on page Manual-4.
COMPRESSOR RATIO control: Once the reshold is
exceeded, the Ratio of input change to output change is deter-
mined by this control. e compressor has no effect when set
at 1:1. But at 10:1, it takes a 10 dB input signal increase above
the reshold to produce a 1 dB increase in Output Gain. See
Figure 2 on page Manual-4.
GAIN REDUCTION LEDs show the amount of average signal
reduction in dB. is aids in setting the THRESHOLD and
RATIO controls by showing how much compression is occur-
ing.
_____________________________________________
BYPASS switch compares the compressed and non-compressed
signal. ere is one for each channel. e INPUT LEVEL
indicators remain active regardless of switch position.
OUTPUT LEVEL control increases or decreases the output
gain of each Channel by 15 dB. In the center detent, gain will
be unity.
LINK switch activates both Compressors when either channel’s
signal exceeds the set reshold, preserving stereo imaging.
Switch this ON when using stereo material. e channel 1
controls become the Master when this switch is active, render-
ing the channel 2 controls and indicators dead.
_____________________________________________
Channel 2 controls duplicate the controls in channel 1. ese
are not active if the LINK switch is engaged.

When the POWER LED is lit, the DC 22S is connected to a
100-240 VAC source and ready to rock.
