The MH-1060X components come pre-assembled to reduce field assembly time. Only three bolts are required to secure the mid-high assembly to the top of a QSC low-frequency enclosure. NOTE: Install in accordance with QSC’s instructions and with the assistance of a licensed professional engineer.

Attaching to Low Frequency Enclosure The mid-high loudspeaker assembly attaches to the top of the QSC low frequency cabinet with three 20-mm-long M8 bolts with lock washers (this hardware is factory installed on the low frequency enclosure). Apply medium-strength threadlocking compound to the bolt threads and attach the mid-high loudspeaker assembly loosely at first so you can aim it properly (see the next section).
— Figure 4 — Do not apply signal with low-frequency content below 200 Hz to the mid/hi input. Low-Frequency Connection Connect the low-frequency amplifier channel output directly to the input terminals of the low-frequency enclosure. Do not connect the amplifier channel or the low-frequency enclosure to the terminals on the mid-high assembly. Output Terminals The upper terminals labeled MND and HN are factory-connected to the drivers, so do not connect anything to them for normal operation.
Passive Mode Connections WAONN GE: Do not connect amplifiers directly to the driver inputs! Always use the input terminal strip. Figure 5 depicts the passive mode connections for the MH-1060X and its companion low-frequency enclosure. Mode Switch To set up the loudspeaker system for passive mode, set the mode switch to PWSSNVT MNDT. To avoid damaging the loudspeaker system or amplifier, always make sure the mode switch is in the proper position and the loudspeaker is wired correctly before operating the system.
