SOURCE INPUT A-D These 1/4" TRS jacks accept a balanced or unbalanced line-level input signal. This is the signal that you add into the headphone mix when you adjust the SOURCE A-D Level Controls [1] on each channel strip. You might connect a submix output from the mixer to these inputs, or a direct output from an individual channel (so the talent can really crank themselves up in the headphone mix if they want to). These mono inputs are routed equally to the left and right phones output. The 1/4" TRS inputs are wired as follows: Sleeve = Shield or ground Tip = Positive (+ or hot) Ring = Negative (­ or cold) 9. When the power switch is turned ON (up), power is supplied to the HMX-56 and the POWER [6] indicator lights up. 10.

The 1/4" TRS inputs are wired as follows: Sleeve = Shield or ground Tip = Positive (+ or hot) Ring = Negative (­ or cold) If you are connecting a mono input signal to these inputs, use a Y-Cord splitter to connect the signal to both inputs. See "Mults and Y's" in Appendix B for more info. 14. Each PHONES output carries its own individual mix as determined by the corresponding channel strip controls. You can also connect an in-ear monitor (IEM) system to the PHONES jack to provide an individual monitor mix. WARNING: The headphone amps are designed to drive any standard headphones to a very loud level. Always start with the PHONES level turned all the way down before connecting headphones to the PHONES jack. Always remember: "Engineers who fry their ears, find themselves with short careers. " 11.
