SC-312X

Cinema Loudspeaker System

Features

Passive, 2-way, screen channel system

SC-312X provides 90° horizontal by +15° to -35° vertical coverage

Low distortion waveguide provides highly articulate dialogue

Shallow depth (20") facilitates installation

Developed specifically for the unique requirements of professional motion picture playback, the SC-312X extends QSC’s commitment to the cinema market. As a member of the DCS Digital Cinema Speaker Series, the SC-312X is a passive, 2-way, screen channel loudspeaker system comprised of two main units—the HF-63X1 high frequency system and the LF-3115 low- frequency system.

The HF-63X1 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-63X1 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-3115 15" (381mm) low-frequency enclosure is designed specifically to address the extended low- frequency response required for cinema applications. The LF-3115 covers the frequency range from 35 Hz to 1000 Hz, depending upon the high- frequency system requirements.

The SC-312X is designed for ease of installation. The HF-63X1 components come pre-assembled to reduce field assembly time. Three bolts are all that are required to secure the HF-63X1 to the top of the LF-3115 enclosure.
