Begin with all LEVEL controls counterclockwise at "0. " Connect the output from any stereo source such as a mixer, CD or MP 3 player, and plug the left and right inputs into the respective INPUT jacks. [. . . ] In some instances a STEREO program may be confusing for live monitoring purposes, and switching to MONO improves intelligibility by summing the Left and Right signals. 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. 4 POWER switch is your basic, straightforward power switch. When the yellow indicator is lit, the HC 4S is ready to go.
