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.
WA N NGE: 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.
