Product description

The CRMSCompact Cinema Reference Monitor System is a 3-way sound system, offering the most natural Digital Cinema and HD audio sound reproduction possible.

Featuring the patented RBN202 pro-ribbon driver, the CRMSC 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, while the very high peak power handling offers a 1:15 RMS-to-peak ratio, enabling maximum screen compensations without any audible stress on the driver.
The patented horizontal dispersion of the RBN202 extends the stereo-imaging to a larger number of seats in the auditorium; Due to the “compression-less” principle of the pro-ribbon transducer, the system has a linear response at any SPL.

Each CRMSCompact system consists of a separate mid-high frequency section, featuring one RBN202 2” pro-ribbon driver HF with non-vented 6.5” midrange and vented 12” low frequency section with low power-compression 4” voice-coil design.

A matching surround system with identical MF/HF components is available, for perfect screen/surround blending, resulting in a very uniform sound stage.

For full system performance, the CRMSC is to be driven by either one or two channels of ALC controller-amplifier, delivering maximum sound quality and utmost operation reliability. The 4 ohms system impedance offers maximum amplifier efficiency.

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

The combination of the outstanding sound reproduction quality and the digital dynamics capability, make the system the ideal choice for high-end mix/screening rooms, post-production facilities, dubbing stages and quality-conscious Home Cinemas with a room depth less than 10m/30ft.

As a result of Alcons’ tight manufacturing standards, all system cabinets are within “matched pair” tolerance.
