QSC Audio Introduces Flyable 4-Way Tri-Amped Speaker System

QSC has announced the new purpose-designed DCS SC-424-8F flyable, four-way, tri-amplified speaker system for Dome and Large Format cinemas that require suspended mounting of screen channels, or point source surround channels.
Making another significant breakthrough in the D-Cinema market, the DCS SC-424-8F joins QSC Audio's popular cinema product lines and follows the success of their award-winning DCP 300 Digital Cinema Processor.
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 unique 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, stated: "This system has been developed specifically for the unique requirements of Multi-Purpose, Large Format and Dome motion picture playback. The two main units comprise the MHV-1090F mid-high/very-high-frequency, 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 to ensure that most of the dialogue is reproduced by a single element, for unmatched intelligibility.
The coaxial neodymium high-frequency/very-high-frequency compression driver provides a dramatic improvement in dynamic response, clarity and transparency, while the annular diaphragms eliminate the break-up of conventional dome drivers that cause a harsh, metallic sound.
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 great 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.
Also available is the companion DCS SC-424-8 system, which provides identical acoustical performance in a standard, non-suspended version.
Outboard digital processing, such as the QSC DCP 300, DCM 30D or Basis is required to provide the active crossover between the low, mid and high-very high frequency drivers. Separate amplifiers are required for the low, mid and high-very frequency channels. The QSC DCA 1644 4-channel amplifier is the ideal choice for the SC-424-8F. Channels 1 and 2 in bridge mode deliver over 800w to the LF enclosure and channels 3 and 4 provide 250w to each of the highly efficient Mid and High frequency horns.
QSC provides a full range of complementary loudspeaker products to meet all of your Large Format cinema speaker needs. From 18 and 21 subwoofers for earthshaking bass to the smallest ceiling speakers for your lobby PA, QSC is the one place to go for loudspeakers, amplifiers, DSP and network remote control. one brand, one call - it couldn't be easier to get great sound.
