[. . . ] HMX-56 Important Safety Instructions 1. Install in accordance with the manufacturer's instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. [. . . ] When the power switch is turned ON (up), power is supplied to the HMX-56 and the POWER [6] indicator lights up. 10. LEFT and RIGHT MAIN INPUT These 1/4" TRS jacks accept a balanced or unbalanced line-level input signal. Connect the main mix output from the mixer to these inputs. 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. PHONES Out 1-6 Plug your headphones into these jacks. 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. They can cause permanent hearing damage. Even intermediate levels may be painfully loud with some headphones. Always start with the PHONES level turned all the way down before connecting headphones to the PHONES jack. Keep it down until you've put on the headphones. Always remember: "Engineers who fry their ears, find themselves with short careers. " 11.
