Cinema Mid-High-Very High Loudspeaker System User Manual

MHV-1090 10” (254mm) mid, coax high- very high compression driver

Introduction

The MHV-1090 system provides the mid, high, and very high frequency components of

four-way screen channel loudspeaker system for high performance cinema applica-

tions. It was designed to operate with and be directly mounted on QSC’s cinema low

frequency enclosures.

The high frequency horn is a low-distortion waveguide providing highly articulate dia-

logue without the coloration associated with conventional horn loudspeakers. Both

horns feature broad horizontal and vertical coverage to ensure audio integrity is deliv-

ered to every seat in the auditorium. The driver assemblies are mounted on an adjust-

able pan and tilt bracket that has an integral aiming sight, simplifying installation.

The MHV-1090 includes a driver protection and high-very high frequency crossover

network to assure reliable operation. DC blocking capacitors protect against DC or

low-frequency signals that could damage an unprotected driver. A 12 dB per octave

crossover seamlessly blends the high and very high frequency elements when oper-

ated in tri-amp mode. Outboard processing is required to form the crossover between

the low, mid, and high-very high frequency drivers.

Tri-amp or quad-amp operation is possible using a selector switch mounted on the

INPUTS connection panel. The tri-amp setting provides a built-in passive crossover

network between high and very high frequency drivers. Separate amplifiers and active

crossovers are required for the low, mid, high-very high frequency channels. Quad-

amp setting disables the internal high-very high frequency crossover and each driver

is driven independently by its own amplifier and active crossover; one each required

for the low, mid, high, and very high frequency drivers.

The MHV-1090 components come pre-assembled to reduce field assembly time. Three

bolts are all that are required to secure the assembly to the top of a QSC low fre-

quency enclosure.

Install in accordance with QSC Audio Product’s instructions and a

licensed, professional engineer. Only use attachments, mounts,

accessories, or brackets specified by QSC Audio Products, Inc. Refer

all servicing to qualified personnel. Servicing is required when the

apparatus has been damaged in any way.

WARNING! Before placing, installing, rigging, or suspending any

speaker product, inspect all hardware, suspension, enclosures,

transducers, brackets and associated equipment for damage. Any

missing, corroded, deformed or non-load rated component could sig-

nificantly 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 which is rated

for the loading conditions of the installation and any possible short-

term unexpected overloading. Never exceed the rating of the hard-

ware or equipment. Consult a licensed, professional engineer when

any doubt or questions arise regarding a physical equipment installa-

tion.
