Product description

The Cinemarray™ CRA30 is a 3-way sound system, designed for Digital Cinema applications where maximum quality cinema sound reproduction with perfect coverage is needed, in large premium cinema theatres.

Featuring three patented RBN401 pro-ribbon drivers, the CRA30 combines a remarkable clarity and intelligibility, with a “non-compressed” linear response at any SPL. With up to 90% less distortion and  a very high 2400W peak power handling, the HF section allows maximum screen compensation without any audible stress on the driver.
The patented horizontal dispersion extends the stereo-imaging to a larger number of seats in the auditorium.

By implementing line-source technology throughout the entire system, a flat SPL coverage from front to rear is realized, with the “proximity” effect dramatically improving the cinema experience for the audience further away from the screen. The precise projection also minimizes unwanted acoustical reflections.

The CRA30N driver arrangement consists of a triple RBN401 pro-ribbon HF driver array, three vented 6.5” mid-range drivers and two vented 15” woofers with 4” voice-coil design for LF reproduction.

The shallow enclosure design of only 36,8cm/14.5-in provides for flexible mounting, claiming only a minimum of space for even a complete array!

The Cinemarray™ system is powered by an ALC Sentinel amplifier loudspeaker controller, offering system dedicated processing, optimisation and protection in factory presets for maximum sound quality and utmost operation reliability..

The Signal Integrity Sensing™ pre-wiring ensures complete cable/connector compensation between the CRA30N and ALC, significantly increasing response accuracy, regardless of cable length and system impedance, with tight and accurate mid and bass response as result.

The CRA30 comes in two versions: Both fitted with the same speaker configuration, the CRA30N (“narrow”) has a smaller vertical projection pattern for the seats further away, whereas the CRA30W (“wide”) features a wider vertical coverage pattern for the seats closer to the screen.
