Developed specifically for the unique requirements
of professional motion picture playback, the SC-412
extends QSC’s commitment to the cinema market. As
a member of the DCS Digital Cinema Speaker Series,
the SC-412 is a two-way, bi-amplified screen channel
loudspeaker system comprised of two main units—the
HF-75 high-frequency system and the LF-4115 low-
frequency system.

The HF-75 high-frequency system features a 3

"

large

format (75mm) titanium diaphragm compression
driver mounted on a custom designed high-frequency
cinema horn with an adjustable pan and tilt bracket.
The HF-75 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-4115 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 1000 Hz, depending upon the high-
frequency system requirements.

The SC-412 is designed for ease of installation.
The HF-75 components come pre-assembled to
reduce field assembly time. Three bolts are all that
are required to secure the HF-75 to the top of the
LF-4115 enclosure.
