the rules of sound ACTIVE SPEAKER
4PRO 3001-A RCF 4PRO 3001-A is an active, wide dispersion 2 way sound reinforcement speaker. It integrates a high power 350 Watt amplifier, with complete electronic processor section and RCF low distortion, high power transducers. The result is a robust, high efficiency accurate system, producing unparalled clarity and transparency for 15” and 1” 2 way speakers. The new 15” inch woofer is the result of the latest refinement in years of RCF experience in compact 2 way speaker applications, resulting in an accurate reproduction of the midbass frequency range and a tight extended bass. The compression driver uses a new 1.5” titanium dome in front of a low compression, optimised geometry, radial phase plug. This innovative design is powered from a high flux neodymium magnet and offers a very open and natural midrange sound and an 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 and Jack 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 Baltic birch plywood enclosure where high density polystyrene end caps guarantee the maximum strength. Woofer and horn are protected from a full front, strong, powder coated, metal grille. The cabinet features three M10 threaded fly points, a 35 mm stand adaptor, two side handles for easy portability.
