the rules of sound ACTIVE SPEAKER
4PRO 3002-SMA RCF 4PRO 3002-SMA is an active, controlled dispersion 2 way symmetric stage monitor. It integrates a high power 400 watt amplifier, a complete electronic processor section and RCF low distortion, high power neodymium transducers. The system is unique in its class for output and vocal intelligibility. The symmetric transducers configuration guarantee the sound coherency between left and right side of the speaker. The new 12” neodymium woofer is the result of the latest refinement in year of RCF experience in compact speakers. Features a 3 ” voice coil, a massive outside ring neodymium magnet, very high efficiency and controlled mid-bass reproduction. The compression driver uses a new 2.5” pure titanium dome featuring a complex geometry suspension and Direct Drive Coil. This innovative design is powered from a high flux neodymium magnet ring offering a very open and natural midrange sound with extreme precision in high frequency reproduction. A generous 2 step class H TAED 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 a 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, system equalisation, transducers phase alignment, limiter and protection functions. The system is visually monitored from 4 status LEDs. All the system is housed in a strong , very lightweight, baltic birch plywood enclosure. The system is protected from a strong, powder coated, metal grille. The cabinet features an ergonomic side aluminum handle for easy transportation.
