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.

Resumen de contenidos para QSC MHV-1090

  • Página 1 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.
  • Página 2 Attaching to Low Frequency Enclosure The MHV-1090 attaches to the top of QSC low frequency enclosures with three 0.75” long 5/16”-18 TPI bolts. ensure the use of lock washers on all bolts. The bolts and washers ship installed on the low frequency enclosure. We recommend the use of serviceable thread locking compound when installing the bolts to prevent loosening due to vibration.
  • Página 3 NOTE! Maintain proper loudspeaker connection polarity throughout the entire system for maximum performance. Do not apply full range signal to the MHV-1090! There is a high/very high frequency passive crossover for tri-amp mode only. There is no crossover connected when operating in quad-amp mode. All required signal processing must be done before the signal is applied to the loudspeaker.
