The DVA T12 is equipped with three class D amplifiers of DIGIPRO G2 series, high efficiency, which delivers high output power in a compact size and low weight. Thanks to its high efficiency the cooling of the amplifier module is obtained statically, thus avoiding the use of a fan. The power supply circuits of the DIGIPRO G2 amplifier has been conceived to work in fullrange mode; thanks to the SMPS (Switched-Mode Power Supplies) technology with PFC (Power Factor Correction) the operation with supply voltages between 100 Vac and 240Vac is guaranteed by ensuring the same sound performances even with floating and non-stabilized power supply systems. The amplifier module is able to deliver 710W (RMS) for the bass section, 350W (RMS) for the mid-section and 350W (RMS) for the treble section. The bass section controls a 12" neodymium woofer (3" voice coil) in a band-pass configuration enclosed inclined inside the box. This configuration guarantees a high SPL and the obtainment of frequencies of up to 60Hz. The mid-section controls two 6.5" neodymium midranges (2" voice coil), enclosed in their own acoustic chamber and horn loaded with a power factor corrector. The plug phases located in front of the cones prevent the vertical phases from overlapping, creating in fact a local array with 6 output slot that increases directivity. The horn design was specifically created to couple it correctly with the DVA T4 modules. The treble section controls three 1" neodymium drivers (1.5" voice coil) positioned vertically on an aluminum support and spaced to optimize the vertical cover. The horn design was specifically created to couple it correctly with the DVA T4 modules.
