The Alcons cinema sound systems are arguably the only Digital-Cinema ready cinema systems, for a number of reasons:

HiFi sound at concert SPL! The RBN pro-ribbon drivers have up to 90% less distortion than any conventional mid/high transducer (@ same SPL), because of the lack of a compression chamber and the light weight diaphragm (with integrated voice-coil).

Perfect speech-intelligibility The fast transient response + the lack of compression “threshold” (the level under which the compression driver doesn’t make enough compression to have actual HF output) brings perfect intelligibility and tonal balance at lowest as well as highest SPL’s.

No listening fatigue Another benefit of the superb transient response and the lack of “time-smear” (a result of the slow moving mass/diaphragm at high frequencies) is the lack of listening fatigue, even after prolonged listening hours.

True 90 degree dispersion The RBN pro-ribbon drivers features Alcons’ patented “Real-90” dispersion in the horizontal plane, up to and beyond 20kHz. This offers patrons a much wider stereo “sweet-spot”, thus more people can enjoy true stereo.

Digital dynamics Where conventional (compression driver) technology has an RMS-to-peak ratio of 1:2 (i.e. 75W RMS / 150W peak), Alcons pro-ribbon drivers have an RMS-to-peak ratio of around 1:15 (i.e. 70W RMS / 1000W peak). Together with the ultra-low power compression (resulting from the patented heat management + the direct air contact of the voice-coil) this enables the maximum dynamic range that 24-bit Digital Cinema has to offer.

Note; In practice, the “fragile-presumed” ribbon diaphragm seems to be much stronger than a compression driver diaphragm, as a result from the light weight moving mass; The compression driver starts to break-up at 8kHz. because the mass can’t follow the speed. With “clarity” frequencies around 16kHz (= twice the problem speed) often boosted more than 6dB (= 4x the power!), the ribbon driver handles this without failure, contrary to compression drivers (break-up is most common reason for compression diaphragm blow-up) > see explanation below.

Fllat SPL throughout the room by utilizing Alcons’ widely recognized line-source technology, the CR4 reduces the normal (-6dB) reduction of SPL coverage from front to rear, dramatically improving the cinema experience for the audience further away from the screen (“proximity” effect).

Very clean signal path As a result of the flat impedance of the pro-drivers, no impedance correction is needed in the crossover. This allows simpler filter designs, placing fewer parts/obstructions in the signal path, thus offering improved clarity and accuracy of the sound even with passive-filtered systems. The “Current-to-light” driver protection, inaudibly protects the drivers for input overload.

Truly accurate mid and bass response; The Alcons systems are SIS pre-wired for SIS (Signal Integrity Sensing) circuit; In combination with the ALC controller amplifier, influences of long speaker cable lengths (typically for cinema!) are completely compensated for (with damping factor of 10.000).

Maximum and reliable performance The front-accessible SDP processing module in the ALC changes the stereo amp into a dedicated powered controller of the Alcons speakers, offering dedicated excursion protection, system –eq, filtering and power control, for maximum component performance.

Space-economic design The ultra-thin enclosure design (CR1 7”/17cm deep, CR2 10”/25cm, CR4 13,7”/35cm) enable mounting behind any screen. With the moveable mid-high section of CR1 and CR2, the directional frequencies can be aimed at the audience, while still enjoying the shallow system depth.

Maximum mounting flexibility The CR1 and CR2 systems can be stacked or flown or wall-mounted behind the screen. Virtually any set-up is possible.

Extended headroom With system equalizing done by the SDP circuit of the ALC controller-amp (instead of by the passive crossover), the passive Alcons systems deliver up to 4dB more system headroom, starting at 800Hz. It’s combining passive-filter amplifier-efficient powering with active-filter component-efficiency output. 

Sustained power output The combination of Class G power amplifier stage with a 210 Joules capacitor bank (ALC4: 400 Joules) makes the ALC deliver super-dynamic and sustained power output for even the most dynamic digital soundtracks.

Easy connection The ALC controller-amplifier features a 15-pin D-connector, that makes connection to processor very simple. The D-connector is fully compatible with existing cinema booth monitors, featuring this type of connector.
