Page 3: Configuration
The AGC-100 may be used to process either a stereo (Left & Right) signal, or it may be used to process two monaural inputs. Each AGC-100 is individually enclosed in an aluminum case and occupies 1/3 of an RM-1 or PMU401 panel mount (1-3/4"... -

AUDIO INPUT The input to the AGC-100 uses five of the ten screw terminals on the rear of the AGC-100: Right High In Right Low In Ground Left High In #10, Left Low In For optimum results, use twisted-pair cable with an overall shield. - Page 6 ON mode. There should be a noticeable reduction in the audio level, obvious to the listener and visible on the LED meters of the AGC-100. When the AGC is switched to the Off / Setup mode, the audio level will recover. It is convenient to use an Input Level control of the AGC-100 to do this;...
