SC-422 Cinema Loudspeaker System

Developed specifically for the unique requirements of professional motion picture playback, the SC-422 extends QSC's commitment to the cinema market. As a member of the DCS Digital Cinema Speaker Series, the SC-422 is a two-way, bi-amplified screen channel loudspeaker system comprised of two main units - the HF-75 high-frequency system and the LF-4215 low-frequency system.

The HF-75 high-frequency system features a large format, 3" (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-4215 dual 15" (381mm) low-frequency enclosure is designed specifically to address the extended low-frequency response required for cinema applications. The LF-4215 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-422 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-4215 enclosure.
