THX Approved Three-Way Screen Channel System for Large (1200 Seats) Theaters
For critical film sound reproduction in large cinemas.
Digital soundtracks on today's feature films have the potential of pushing traditional two-way speaker system designs beyond their performance limits. Requirements for wide dynamic range, high power handling and low distortion dictate the need for a new standard of performance for today's premier cinemas.
The 5000 Series Cinema Systems feature true three-way system design, with each section optimized for its specific bandpass region. All systems feature the best of JBL transducer and horn technology to produce a system design with maximum power handling capability and acoustic power output, with extremely low distortion. The system has been designed with particular attention to power response and directivity control, allowing seamless transitions between the three acoustic sections and smooth timbral character, consistent with current industry listening standards. The 5674 is JBL Professional's most advanced cinema system for behind screen applications.
The 5674 is intended for tri-amplified use, utilizing JBL's DSC family of digital controllers. Crossover, signal alignment, and equalization can be accomplished using three channels of digital signal control, using factory pre-set tunings, for optimum performance from the 5674.
The 5674 consists of three sections: high frequency horn/driver, midrange horn/driver, and low frequency enclosure. The JBL 2352 Optimized Aperture Bi-Radial horn with the JBL 2451H compression driver provides exceptionally low-distortion high frequency output due to JBL's new "rapid flare" horn and driver design. The 2451H is a 1.5 inch exit driver with a neodymium magnet structure and pure titanium 100 mm diaphragm. The mid range section features JBL's 2392 Optimized Aperture Bi-Radial horn, coupled with the JBL 2490H 3 inch-exit compression driver, designed specifically for the critical midrange region. The low frequency section of the 5674 uses a new-design 23.5 cubic foot (total net internal volume) enclosure with four JBL 2226H VGC drivers in a unique DiamondQuad array. The DiamondQuad array orientation allows the four drivers to create maximum output, while minimizing destructive interference effects caused by the use of multiple drivers operating in the same bandpass region.
