The CRMS, Cinema Ribbon Monitor System is a unique hybrid 3-way main- /2-way surround-system.
Each system consists of a separate mid-high frequency (“MHF”) section, featuring one RBN401 pro-ribbon driver HF with non-vented 8” MF and a low frequency 15” (“LF”) section, with low power-compression 4” voice-coil.
The MHF section is specifically designed to act both as MHF section for the main/front system, as well as full-range surround system. This unique design results in a very uniform and high resolution sound stage throughout the entire listening area.

Featuring the patented RBN401 pro-ribbon driver, the CRMS combines a remarkable clarity and intelligibility, with a unusually high headroom SPL. The Alcons pro-ribbon drivers have up to 90% less distortion than any conventional mid/high transducer (@ same SPL); Due to the “direct-drive” principle of the pro-ribbon transducer (no compression threshold), the system has the same tonal balance from the lowest to the highest SPLs.

The patented “Real-90” horizontal dispersion of the RBN401 extends the stereo-imaging to a larger number of seats in the auditorium and/or widens the “sweet-spot in near-field (studio) applications.
The very high peak power handling of the RBN401 pro-ribbon driver (800W) offers true Digital-Cinema-ready performance, with a 1:16 dynamic ratio, while enabling maximum screen compensations without any audible stress on the HF driver.

Due to the absence of a large (compression) horn, the system depth is only 33.5cm/ 13.2in. enabling flush-mounted or free-standing installation in even the most shallow spaces.

Powered and controlled by the ALC (Amplified Loudspeaker Controller), the CRMS system has its own dedicated speaker drive, making a complete synergetic sound reproduction chain with precisely matched components. There’s a choice of analogue (SDP) and digital (DDP) processing modules, where the analogue system offers non-latency pre-set controlling, and the digital system offers system settings, “on-board” parametric equalizing, delay per section, user presets, a.o.

The so-called “Signal Integrity Sensing™” in the ALC ensures complete cable and connector resistance compensation, raising the damping factor to a mere 10.000. This results in a tight and accurate mid and bass response. Furthermore, SIS™ pre-wiring reduces distortion, both linear (uneven frequency response) and non-linear (InterModulationDistortion).

By exclusively focusing on component quality, Alcons developed a new “sound-for-picture” reference system, with which the absolute maximum performance of a.o. Digital Cinema is obtained. As a result of Alcons’ tight manufacturing standards, all system cabinets are within “matched pair” tolerance.
