Description

Q-SYS SC-412C Bi-Amp 2-Way 1x15-inch Cinema Loudspeaker System with HF-75C and LF-4115

Developed specifically for the unique requirements of professional motion picture playback, the SC-412C extends QSC’s commitment to the cinema market. As a member of the DCS Digital Cinema Speaker Series, the SC-412C is a 2-way, bi-amplified screen channel loudspeaker system comprised of two main units—the HF-75C high-frequency system and the LF-4115 low-frequency system.

The HF-75C high-frequency system features a 3” large format (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 could potentially 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 ensures more reliable operation, keeping the show going.

The LF-4115 15” (381mm) low-frequency enclosure is designed specifically to address the extended low-frequency response required for cinema applications. The LF-4115 covers the frequency range from 32 Hz to 1000 Hz, depending upon the high-frequency system requirements.

The SC-412C 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-4115 enclosure.
