Maintenance and Repair
WARNING!: Advanced technology, including the use of modern materials and powerful electronics, requires specially
adapted maintenance and repair methods. To prevent unnecessary damage to the loudspeaker, injuries to persons, and/or
the creation of additional safety hazards, all maintenance or repair work on the loudspeaker should be performed only by a
QSC authorized service station or an authorized QSC international distributor. QSC is not responsible for any injury, harm or
related damages arising from any failure of the customer, owner, or user to facilitate those repairs.

Introduction
The MH-1060X “mid-high pack” provides the mid and high frequency components
of three-way screen channel loudspeaker systems for high performance cinema
applications. They were designed to operate with and be directly mounted on QSC’s
cinema low-frequency enclosures.
Mid frequencies are reproduced with a 10” (254 mm) high-efficiency, phase-ring
loaded driver mounted on a custom designed cinema horn. The high-frequency
driver is a large format, 2.4" (60 mm) titanium diaphragm compression driver
mounted on a custom high-frequency cinema horn. The high frequency horn
is a low-distortion waveguide that provides highly articulate dialogue without
coloration associated with conventional horn loudspeakers. Both horns feature
broad horizontal and vertical coverage angles to ensure coverage of every seat in
the auditorium. The driver assemblies are mounted on an adjustable pan and tilt
bracket that has an integral aiming sight to simplify installation.
The MH-1060X loudspeaker includes a passive crossover network with a 2400Hz
crossover between mid- and high-frequency drivers.
Operating in bi-amp mode requires outboard processing to produce the low-
frequency and mid-high-frequency bands, as well as two channels of amplification
for them.
Operating in passive mode adds a 570Hz crossover point between the LF and MF
drivers. Together with a QSC low-frequency enclosure, this creates a three-way
loudspeaker system that operates from a full-range amplifier channel output.
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. Only use attachments,
mounts, accessories, or brackets specified or approved by QSC, LLC.
Refer all servicing to qualified personnel. Service is required if the
loudspeaker has been damaged in any way.
WARNING!: Before placing, installing, rigging, or suspending
any loudspeaker product, inspect all hardware, suspension,
cabinets, transducers, brackets and associated equipment for
damage. Any missing, corroded, deformed or non-load rated
component could significantly reduce the strength of the
installation, placement, or array. Any such condition severely
reduces the safety of the installation and should be immediately
corrected. Use only hardware that is rated for the loading
conditions of the installation and any possible short-term
unexpected overloading. Never exceed the rating of the
hardware or equipment. Consult a licensed professional
engineer when any doubt or questions arise regarding a physical
equipment installation. — Figure 1 —

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
CAUTION!: 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 BI-AMP MODE. 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 MID/HI INPUT terminals.
The passive crossover network will properly divide the audio spectrum between the mid- and high-frequency loudspeaker drivers.

TD-001607-01-A
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 MID and HI are factory-connected to the drivers, so do not connect anything to them for normal operation.
The PASSIVE LF OUTPUT terminals are not used in bi-amp mode.
NOTE: Maintain correct polarity at every connection throughout the entire system for optimum performance. Do not connect any
signal to the MID and HI terminals.

Passive Mode Connections
CAUTION!: 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 PASSIVE MODE. 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.
In passive-mode operation, apply full-range audio from the amplifier output to the pair of FULL RANGE INPUT terminals. The passive
crossover will properly divide the audio spectrum among the loudspeaker drivers.
Output Terminals
The upper terminals labeled MID and HI are factory-connected to the drivers, so do not connect anything to them for normal operation.
The pair of terminals labeled PASSIVE LF OUTPUT connect to the INPUT terminals of the low-frequency loudspeaker enclosure. Use the
wire included or a large-gauge (up to 6mm² or #10 AWG) and reasonably short pair of stranded copper wire to make the connection. This is the
output of the passive crossover's low-pass output.
NOTE: Maintain correct polarity at every connection throughout the entire system for optimum performance. Do not connect any
signal to the MID and HI terminals.
