Alcons Extends its Digital Cinema Compliance

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.

Extending Alcons’ evolutionary Digital Cinema sound system program, the company developed the CR3 thee-way pro-ribbon cinema screen system, specifically aimed at medium sized applications, where excellent projection control and superb, 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 SPL’s, 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.

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

The 40° vertical cylindrical projection of the HF section (inclusive screen spreading compensation), in combination with the 10º 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 6-years limited warranty.

The shallow system design of 35cm/13,7” guarantees space economic mounting, that could even add an extra (money-making) row of seats.

The Signal Integrity Sensing™ pre-wiring ensures complete cable/connector compensation between the CR3 and ALC Sentinel; This offers an undistorted natural sound reproduction, regardless of cable length and amplifier impedance load (system damping factor >10.000 down to 2 ohms).
