Developed specifically for the unique requirements
of professional motion picture playback, the SC-413
extends QSC’s commitment to the cinema market. As
a member of the DCS Digital Cinema Speaker Series,
the SC-413 is a three-way, selectable bi or tri-amplified
screen channel loudspeaker system comprised of two
main units—the MH-1063 mid-high frequency system
and the LF-4115 low-frequency system.
The MH-1063 mid-high system features a high
output, horn loaded 10" midrange cone driver and
a 2.5" (63mm) titanium diaphragm compression
driver mounted to an adjustable pan and tilt bracket.
The MH-1063 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-1063 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-4115 single 15" (381mm) low-frequency
enclosure is designed specifically to address the
extended low-frequency response required for cinema
applications. The LF-4115 covers the frequency range
from 35 Hz to 250 Hz.
The SC-413 is designed for ease of installation.
The MH-1063 components come pre-assembled to
reduce field assembly time. Three bolts are all that
are required to secure the MH-1063 to the top of the
LF-4115 enclosure.
