the rules of sound ACTIVE SPEAKER
ART 322Ai RCF ART 322-Ai is an active, wide dispersion 2 way sound reinforcement speaker. It integrates a high power 400 Watt amplifier, with a complete electronic processor section and RCF Precision Series low distortion, high power transducers. The result is a compact, high power accurate system, incredible for linearity and vocal intelligibility. This new high power 12” inch woofer is the result of the latest refinement in years of RCF experience in compact 2 way speaker manufacturing, resulting in a fast and accurate reproduction of the midbass frequency range and tight deep bass. Features a 3” inside/outside voice coil to minimize power compression and extend the life of this product. The compression driver uses a 0.05 mm pure titanium dome featuring a complex geometry suspension and Direct Drive coil. This innovative design is powered from a massive high flux neodymium magnet and an edge wound 64 mm aluminium voice coil. This unique driver offers a transparent midrange sound and extreme fidelity in high frequencies reproduction. A generous 2 step class H TAED amplifier design is used to power the low frequencies and the compression driver amplifier is a warm and clear class AB design. The input section offers an XLR and Jack input connector that is switchable from microphone to line levels. A master volume knob and a useful XLR loop-through link guarantee the best versatility. The processor section includes active crossover, system equalization, transducer phase alignment, limiter and protection functions. The system is visually monitored from 4 status LEDs. All components are housed in a strong, lightweight, polypropylene composite enclosure. Woofer and compression driver throat are protected from a strong, powder coated, metal grille. The cabinet shape is perfect for monitoring applications. The cabinet features four M10 threaded fly points, a 35 mm pole mount adaptor, two side handles and an ergonomic top handle.
ACOUSTICAL SPECIFICATIONS Applications With the perfect blend of the fast, high efficiency transducers, ART 322-Ai offers an extremely linear response and precise, deep low frequency control. The ideal cabinet for main front of house PA and monitoring, ART 322-A is the perfect solution where the power of a 2” compression driver is required for longer throw applications in larger venues.
