Eight years after the introduction of the original, Alcons launches the mkII version
of its successful CRMS Cinema Reference Monitor System.
The CRMS is a 3-way sound system design to offer the most natural 1:1 Digital
Cinema and HD audio sound reproduction possible.
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,
while the very high peak power handling offers a 1:16 RMS-to-peak ratio, enabling
maximum screen compensations without any audible stress on the MHF
performance.
The patented horizontal dispersion of the RBN401 extends the stereo-imaging and
depth-of-field 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, from the quietest whisper to the loudest explosion or drum
solo.
The CRMS system consists of a separate, adjustable mid-high frequency section,
featuring one RBN401 4′ pro-ribbon driver HF with non-vented 8′ mid-range driver
and a vented low frequency section with 15′ woofer with low power-compression 4′
voice-coil design.
A matching surround system with identical MF/HF components, CRMS-SR, is
available, offering perfect screen/surround blending, resulting in a very uniform
sound stage and a seamless transition between surround positions in an immersive
sound system.
For full system performance, the bi-amped CRMS is to be driven by two channels of
ALC Sentinel controller-amplifier, delivering maximum sound quality and utmost
operation reliability.
System-dedicated processing presets, SIS™ sensing circuit, 4-channel HiFi-grade
amplifier stages, 4-in/4-out 192kHz AES3 signal inputs make the ALC Sentinel the
ideal drive for the Alcons CRMS.
The 4 ohms system impedance offers maximum amplifier efficiency.
The Signal Integrity Sensing™ (SIS™) pre-wiring ensures complete cable/connector
compensation between the CRMS and ALC, significantly increasing response
accuracy regardless of cable length and system impedance, with tight and accurate
mid and bass response as result (system damping factor of 10.000); SIS™ further
reduces linear and non-linear distortion and makes position of the amplifier none
critical to ensure best performance.
With a system depth of only 32cm/ 12.6in., a complete system can be installed in
even the most shallow spaces. The system can both be free-standing as well as
flush-mounted. The recommended CB181sl subwoofer has a depth of only
25cm/10-in.
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 20m/60ft.
The CRMS system was installed at Lucasfilm Singapore, NBC Universal Beijing,
Factory studios London, a.o. as well as numerous premium home-theatres around
the world.
