description

The CR4 is a 3-way sound system, designed to meet all requirements of current and future (Digital) Cinema sound formats.
Featuring the patented Alcons pro-ribbon driver technology, with triple RBN401 pro-ribbon HF driver array, the CR4 is designed for applications where high output with maximum quality cinema sound reproduction is needed. It is recommended for 300-500 seat theatres.

By implementing line-source technology throughout the entire system (an industry first), the normal (-6dB step) reduction of SPL coverage from front to rear is reduced; this “proximity” effect dramatically improves the cinema experience for the audience further away from the screen. The precise projection also prevents unwanted ceiling reflections.

The CR4 HF section has a 2400W peak power input, offering a 1:16 dynamic range with up to 90% less distortion from 1kHz. to beyond 20kHz. The patented Real-90 horizontal dispersion widens the stereo experience for far left and right seated audience.

The CR4 is available with bi-amp filtering for economical powering or tri-amp filtering for maximum system output.

The SignalIntegritySensing™ pre-wiring ensures complete (long!) cable/connector compensation between CR4 and ALC, significantly increasing response accuracy and further reducing distortion. The (industry’s most) shallow enclosure design of only 35cm/13,7” provides for flexible mounting, claiming only a minimum of space behind the screen.

For full system performance, it is strongly recommend using the CR4 in combination with an ALC2 (or ALC4) amplifier/controller. Driven by the ALC, the CR4 delivers maximum sound quality with increased headroom under dedicated equalisation and inaudible (power and excursion) protection (SDP circuit).
