Developed specifically for the unique requirements of professional motion picture playback, the SC-322X extends QSC’s commitment to the cinema market. As a member of the DCS Digital Cinema Speaker Series, the SC-322X is a passive, two-way screen channel loudspeaker system comprised of two main units—the HF-63X2 high-frequency system and the LF-3215 low- frequency system.

The HF-63X2 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- 63X2 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-322X is designed for ease of installation. The HF-63X2 components come pre-assembled to reduce field assembly time. Three bolts are all that are required to secure the HF-63X2 to the top of the LF-3215 enclosure.
