[. . . ] 2 PHONES jacks accept standard ¼" and 3. 5mm TRS (tip-ring-sleeve) stereo headphone plugs. 3 LEVEL controls adjust the volume for each set of headphones as they are driven from the rear INPUTS. It's always a good idea to keep this control turned down before plugging in a pair of phones, then turn it up slowly. The red OL indicators light when the input signal exceeds the HC 4S's output capability (3 dB below maximum). Occasional flickering is acceptable, but a steady glow recommends turning the LEVEL control down. The overload point automatically varies with the headphones used. When the yellow indicator is lit, the HC 4S is ready to go. Rear Panel Description 100-240 V 50/60 Hz 7 WATTS CONNECTION COMMERCIAL AUDIO EQUIPMENT 24TJ INPUTS LEFT RIGHT HC 4S MADE IN U. S. A.
