Developed specifically for the unique requirements

of professional motion picture playback, the SC-433

extends QSC’s commitment to the cinema market. As

a member of the DCS Digital Cinema Speaker Series,

the SC-433 is a three-way, selectable bi or tri-amplified

screen channel loudspeaker system comprised of two

main units—the MH-1075 high-frequency system and

the LF-4315 low-frequency system.

The MH-1075 mid-high system features a high

output, horn loaded 10 midrange cone driver and a "

3 (75mm) titanium diaphragm compression driver "

mounted to an adjustable pan and tilt bracket. The

MH-1075 includes a driver protection network and

a passive crossover for bi-amp operation. Power

limiter circuitry protects the high-frequency driver

from overpowering. The MH-1075 provides extended

frequency coverage for the critical midrange band. A

high power 10 cone driver allows operation as low "

as 250 Hz and the advanced phase plug coupling

permits a crossover point of up to 1800 Hz to the

high-frequency horn. This ensures that most of the

dialog range is reproduced by a single element, for

unmatched intelligibility.

The LF-4315 triple 15 (381mm) low-frequency "

enclosure is designed specifically to address the

extended low-frequency response required for cinema

applications. The LF-4315 covers the frequency range

from 35 Hz to 250 Hz. Close Coupled Woofers

(CCW), with their tight spacing between woofers,

improves coupling and keeps coverage angles wide

over a greater frequency range than more widely

spaced designs.

The SC-433 is designed for ease of installation.

The MH-1075 components come pre-assembled to

reduce field assembly time. Three bolts are all that

are required to secure the MH-1075 to the top of the

LF-4315 enclosure.

Cinema Mid-High Loudspeaker System User Manual

MH-1063 10” (254mm) mid, 2.5” (63mm) compression driver

MH-1075 10” (254mm) mid, 3.0” (75mm) compression driver

Introduction

The MH-1063 and MH-1075 “mid-high packs” provide 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” (254mm) high-efficiency, phase-ring

loaded driver mounted on a custom designed cinema horn. The high-frequency driver

is a large format, 2.5” (63mm, MH-1063) or 3.0” (75mm, MH-1075) titanium dia-

phragm 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 conventional horn loudspeakers. Both horns fea-

ture 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, simplifying installation.

The MH-1063 and MH-1075 loudspeakers include 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-1063 and MH-1075 components come pre-assembled to reduce field assem-

bly time. Three bolts are all that are required to secure the mid-high assembly to the

top of a QSC low frequency 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, cabinets, trans-

ducers, 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 which 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. TD-000180-00 rev.A
