Features
• Three-way selectable, bi or tri- amplified screen channel system
• MH-1075 provides 90° horizontal by +20° to -30° vertical coverage
• LF-4315 is constructed of MDF and features single woofer chambers
• Low-distortion waveguides provide highly articulate dialogue
• Shallow depth (20") facilitates installation
• THX™ approved for professional cinema applications
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.
