Developed specifically for the unique requirements
of professional motion picture playback, the SC-322
extends QSC’s commitment to the cinema market. As
a member of the DCS Digital Cinema Speaker Series,
the SC-322 is a two-way, bi-amplified screen channel
loudspeaker system comprised of two main units—the
HF-63 high-frequency system and the LF-3215 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-3215 dual 15

(381mm) low-

frequency enclosure is designed specifically to address
the extended low-frequency response required for
cinema applications.

The LF-3215 covers the frequency range from 35 Hz to
1000 Hz, depending upon the high-frequency system
requirements. 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-322 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-3215 enclosure.
