Developed specifically for the unique requirements
of professional motion picture playback, the SC-312
extends QSC’s commitment to the cinema market. As
a member of the DCS Digital Cinema Speaker Series,
the SC-312 is a two-way, bi-amplified screen channel
loudspeaker system comprised of two main units—the
HF-63 high frequency system and the LF-3115 low-
frequency system.
The HF-63 high-frequency system features a 2.5"
(63mm) titanium diaphragm compression driver
mounted on a custom designed high frequency
cinema horn with an adjustable pan and tilt bracket.
The HF-63 includes a driver protection and equalization
network. DC blocking capacitors protect against DC or
low-frequency signals that would likely destroy an
unprotected driver. Power limiter circuitry protects the
driver from overpowering and a response correction
filter smoothes the frequency response of the horn/
driver combination. The driver and equalization
network provides for more reliable operation, ensuring
the show will go on.
The LF-3115 15" (381mm) low-frequency enclosure
is designed specifically to address the extended low-
frequency response required for cinema applications.
The LF-3115 covers the frequency range from
35 Hz to 1000 Hz, depending upon the high-
frequency system requirements.
The SC-312 is designed for ease of installation.
The HF-63 components come pre-assembled to
reduce field assembly time. Three bolts are all that
are required to secure the HF-63 to the top of the
LF-3115 enclosure.
