Cinema Mid-High Loudspeaker System User Manual
MH-1075C 10” (254mm) mid, 3.0” (75mm) compression driver
Introduction
The MH-1075C “mid-high pack” provides the mid and high frequency components of
three-way screen channel loudspeaker systems for high performance cinema applica-
tions. They were designed to operate with and be directly mounted on QSC’s cinema
low-frequency enclosures.
Mid frequencies are reproduced with a 10” (254mm) high-efficiency, phase-ring
loaded driver mounted on a custom designed cinema horn. The high-frequency driver
is a large format, 3.0” (75mm) titanium diaphragm compression driver mounted on a
custom high-frequency cinema horn. The high frequency horn is a low-distortion
waveguide providing highly articulate dialogue without coloration associated with con-
ventional horn loudspeakers. Both horns feature broad horizontal and vertical cover-
age 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,
simplifying installation.
The MH-1075C loudspeaker includes a driver protection and crossover network to
assure reliable operation. DC blocking capacitors protect against DC or low-frequency
signals that could damage an unprotected driver. Power limiter circuitry protects the
driver from over-powering and an 18dB/octave crossover seamlessly blends the high
and mid frequency elements. Outboard processing is required to form the crossover
between the LF and MH loudspeakers.
Bi-amp or tri-amp operation is possible using a selector switch mounted on the con-
nections panel. The bi-amp setting provides a passive crossover network between
mid and high drivers. Separate amplifiers and an active crossover are required for the
low frequency channel and the mid-high channel. Tri-amp setting disables the internal
mid-high crossover and each driver is driven independently by its own amplifier and
active crossover; one for the low, one for the mid, and one for the high frequencies.
The MH-1075C components come pre-assembled to reduce field assembly time.
Three bolts are all that are required to secure the mid-high assembly to the top of a
QSC low-frequency enclosure.
