Developed specifically for the unique
requirements of professional motion
picture playback, the SC-222X extends
QSC’s commitment to the cinema market.
As a member of the DCS Digital Cinema
Speaker Series, the SC-222X is a passive,
2-way screen channel loudspeaker
system comprised of two main units—the
HF-75CX2 high-frequency system and the
LF-2215 low-frequency system.
The HF-75CX2 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-75CX2 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-222X is designed for ease of
installation. The HF-75CX2 components
come pre-assembled to reduce field
assembly time. Three bolts are all that are
required to secure the HF-75CX2 to the
top of the LF-2215 enclosure.
