Developed specifically for the unique
requirements of professional motion
picture playback, the SC-222 extends
QSC’s commitment to the cinema
market. As a member of the DCS Digital
Cinema Speaker Series, the SC-222 is
a bi-amplified, 2-way screen channel
loudspeaker system comprised of two
main units—the HF-75C high-frequency
system and the LF-2215 low-frequency
system.
The HF-75C high-frequency system
features a 3” (75mm) titanium diaphragm
compression driver mounted on a custom
designed high-frequency cinema horn
with an adjustable pan and tilt bracket.
The HF-75C 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 smooths the frequency response of
the horn/driver combination. The driver
and equalization network provides for
more reliable operation, ensuring the
show will go on. LF-2215 dual 15” (381
mm) low-frequency enclosure is designed
specifically to address the extended low-
frequency response required for cinema
applications.
LF-2215 covers the frequency range from
37 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-222 is designed for ease of
installation. The HF-75C components
come pre-assembled to reduce field
assembly time. Three bolts are all that are
required to secure the HF-75C to the top
of the LF-2215 enclosure.
