Both the Mid/High and LF enclosures are built with common dimensions to facilitate easy installation in vertical or horizontal arrays and are constructed of heavily braced, 15mm concert tour-grade plywood. In addition, 16 M10 attachment points-per-enclosure are provided for safe and easy suspension.
The DCS SC-424-8F also features a coax HF/VHF diaphragm, which has less mass than traditional diaphragms, resulting in "exceptional dynamic range, extended high frequency response and lower distortion".
Francois Godfrey, QSC director of sales, cinema states: "This system has been developed specifically for the specific requirements of multi-purpose, large format and dome motion picture playback. The two main units comprise the MHV-1090F mid-high / very-high-frequency system, and the LF-4215-8F low-frequency system aimed purposely at applications where a point-source surround channel or screen channel must be suspended or flown rather than mounted on a platform or floor."
The MHV-1090F mid-high / very-high-frequency system features a high output, horn loaded 10" midrange cone driver and a coaxial neodymium high-frequency / very high-frequency compression driver. The MHV-1090F includes a driver protection network and a passive crossover for tri-amp operation. A high power 10" cone driver allows operation as low as 250 Hz and up to 1800 Hz.
The LF-4215-8F dual 15 (381 mm) low-frequency enclosure is designed for safe and easy suspension via M10 fly points. The heavily braced, tour grade construction cabinet provides strength while keeping weight to a minimum.
The SC-424-8F is designed for ease of installation. The MHV-1090F and LF-4215-8F components come pre-assembled to reduce field assembly time, and both enclosures have the same dimensions to allow stacked or side-by-side arrays. Each enclosure is fitted with 16 x M10 fly points for safe and secure suspension via installer-provided mounting hardware.
