the rules of sound ACTIVE SPEAKER
ART 315A RCF ART 315-A is an active, wide dispersion 2 way sound reinforcement speaker. It integrates a high power 350 Watt amplifier, a complete electronic processor section and RCF low distortion, high power transducers. The result is a compact, high power accurate system, unique in his class for clarity and low distortion. The new 15” inch woofer is the result of the latest refinement in years of RCF experience in compact 2 way speakers, resulting in an accurate reproduction of the midbass frequency range and a tight punchy bass. The compression driver uses a new 1.5” mylar dome in front of a low compression, optimised geometry, radial phase plug. This innovative design is powered from a high flux neodymium magnet offering a very open and natural midrange sound with extreme precision in high frequency reproduction. A generous 2 step class H design is used to power the low frequencies and the compression driver amplifier is a warm and clear class AB design. The input section presents an XLR input connector that is switchable from microphone to line levels. A master volume control and a useful XLR loop-through link guarantee the best versatility. The processor section includes active crossover, 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 features four M10 threaded fly points, a 35 mm stand adaptor plus two side handles and an ergonomic top handle.
ACOUSTICAL SPECIFICATIONS Applications ART 315-A is the perfect speaker for live sound situations where you need extra punch in bass reproduction and extremely accurate high frequency response. Thanks to the versatility in both monitoring and playback installation situations representing the ideal multipurpose solution.
