the rules of sound ACTIVE SPEAKER
4PRO 4001-A RCF 4PRO 4001-A is an active, wide dispersion 3 way sound reinforcement speaker. It integrates a massive 800 Watt amplifier, a complete electronic processor section and RCF low distortion, high power transducers. The system is compact and extremely linear and offers the typical balanced sound of high level three way systems. The new 15” inch woofer is the result of the latest refinement in years of RCF experience in compact speaker design and manufacture, resulting in an accurate and a tight extended bass. RCF’s unique 6” cone midrange is built in and optimised for the 4PRO 4001-A horn assembly. Specific attention has been dedicated to low distortion and dynamic properties of this transducer. 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 offering extreme precision in high frequency reproduction. A high current 2 step class H design is used to power the low frequencies.Mid and high frequencies are separately powered from class AB dedicated low distortion designs. The input section presents a combo XLR/Jack line input connector, a recessed master volume and a useful XLR loop-through link. 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. The woofer and mid-high horn is protected from a full front, strong, powder coated, metal grille. The cabinet features three M10 threaded fly points and two side handles for easy portability.
