Mounting
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). Once the system is properly aimed, tighten the
fasteners.
Aiming
Aim the horn in the horizontal plane (pan) before tightening the attachment hardware. Adjust the vertical tilt with the mid-high vertical adjustment
bracket. The mid-high assembly features an aiming sight to help you optimize coverage quickly and easily. For typical applications, the aim point
should be the center seat in the back row of the auditorium. If the cinema screen has already been installed, set a flashlight at the desired aim
point; in a darkened auditorimum it is easily visible through the screen perforations.
Bi-Amp Mode Connections
WAONN GE:
Do not connect amplifiers directly to the driver inputs! Always use the input terminal strip.
Figure 4 depicts the bi-amp mode connections for the MH-1060X and its companion low-frequency enclosure.
Mode Switch
To set up the loudspeaker system for bi-amp mode, set the mode switch to
BN-WMP 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.
Input Terminals
The MH-1060X has barrier strip screw terminals that accept up to 6 mm² or #10 AWG stranded loudspeaker wire. Observe proper polarity and use
the largest wire gauge and shortest length that is practical for the application.
Bi-amp mode requires the use of outboard processing to split the spectrum of the audio channel into the low-frequency band and the mid-high
band, then amplifying the two bands separately. Connect the output of the mid-high amplifier channel to the pair of
MND/HN N PAO
terminals.
The passive crossover network will properly divide the audio spectrum between the mid- and high-frequency loudspeaker drivers.
