With the digital cinema standard of 24-bit, up-to-16-channels of PCM non-compressed audio, now becoming reality, new challenges have arrived for existing equipment. Upgrading with just higher powered versions of existing solutions is just not enough to benefit from the new audio standard; speech, music and effect should be reproduced with non-compressed non-colored detail, with lowest distortion and fullest digital dynamics. Alcons has introduced the CR3 screen system to address the problem.

The Alcons CR3Extending Alcons’ digital cinema sound system program, the company developed the CR3 three-way pro-ribbon cinema screen system, specifically aimed at medium sized applications, where projection control and 1:1 accurate, non-compressed digital sound reproduction is required.

It is designed to meet and exceed all requirements of current and future digital cinema sound formats,

Due to the multiple-patented Alcons pro-ribbon transducer technology, the CR3 offers a unique linear response to above 20.000Hz. The absence of a compression mechanism caters for the same tonal balance from the lowest to highest SPLs, while the patented Real-90 horizontal dispersion of the pro-ribbon transducer guarantees a very stable sound field throughout the operating bandwidth. This also widens the stereo experience for far left- and right-seated audience members.

The driver arrangement consists of a double RBN401 pro-ribbon HF driver array, two 6.5-inch mid-range drivers and two vented 15-inch woofers for LF reproduction. The CR3 HF section has a 1600W peak power input, enabling a 1:16 dynamic range with up to 90 percent less distortion from 1kHz to beyond 20kHz.

The 40-degree vertical cylindrical projection of the HF section (inclusive screen spreading compensation), in combination with the 10-degree pre-tilt, caters for a very precise projection control, preventing unwanted ceiling reflections.

The bi-amped CR3 is powered and controlled by the ALC Sentinel amplified loudspeaker controller; Through the integrated processing and feedback, the Sentinel offers CR3-specific drive processing with optimal response and reliability. And is then covered by a six-years limited warranty.

The shallow system design of 35cm/13,7-inches guarantees space economic mounting that could even add an extra row of seats for more revenue.
