DESCRIPTION
The 4PRO 3031-A is a two-way active bass reflex loudspeaker offering
exceptional full range and accurate reproduction. It integrates a 600 Watt digital bi-amplifiication, 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 two way systems.
The 90° angle is wide enough to provide coverage of an audience when used
one per side, yet narrow enough to allow displaying of multiple enclosures
without excessive coverage overlap.
The 15” woofer delivers a fast and accurate reproduction of the midbass
frequency range and controlled deep bass while the 1” compression driver
offers a very open and natural midrange sound and extreme precision high
frequencies reproduction. The 4PRO 3031-A comprises a 15” woofer and a
1.7” voice coil compression driver that is mounted to a 90° x 60° constant
directivity horn.
4PRO 3031-A are equipped with a new generation of 600 Watt Digital
Amplifier, 400 Watt for the woofer and 200 Watt for the compression
driver. The result of this is very high output, extremely low distortion and
an incredible natural sound. The amplifier presents both XLR/jack (Combo)
balanced inputs, XLR output link, volume, a switchable EQ Mode (Contour)
and a mic/line switch. The amplifier features a solid mechanical aluminium
structure which not only stabilize the amplifier during transportation but also
assist in the heat dissipation.
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 front is protected from a strong, powder coated, metal grille. The cabinet
features two comfortable recessed side handles for easy portability.
