The DVA T4 is equipped with unique digital power amps that provide a total of 420W RMS.
Driven by Digipro® technology, it renders signals very accurately thanks to a multiband compressor/ limiter with separate response curves for each signal path. The 8“ Neodymium-Woofer is equipped with a high power 2.5“ voice coil to provide superior sound pressure level in a very compact size. The 6.5“ Neodymium-Midrange speaker has a sealed basket to provide an optimized volume capacity including high sensitivity and superb sound reproduction. It also has a horn exit including phase plug for defined and linear sound emission. The build in 1”Neodymium- Drivers are equipped with a 1.4” Mylar- Membrane which allow a very quick response and provide a linear frequency range at a surprisingly low weight.

TECHNOLOGIES
Neodymium TransducersNeodymium is a metal belonging to the family of the “rare earth”, a particular material which creates a powerful magnetic field once charged. This material, used in acoustic transducers, possesses a far superior magnetic power compared to the classical ferrite which allows its dimensions to be reduced, favoring its weight and space capacity.
PFC (Power Factor Corrector)The Power Factor Corrector greatly improves the efficiency of the system. Performances of the amplifier are very stable and consistent, regardless of the quality of the mains. This also grants a worldwide compatibility of the power supply - from 90V to 265V 50/60Hz - and limits power consumption.
Preset SystemThe opportunity of modifying the character and equalization of a speaker is a very important prerogative in adapting a speaker to multiple functions. The introduction of the Preset System enables to choose directly from the box the most adeguate equalization for the desired use, optimizing performances without the need of external processors. The management of phase, limiter and x-over will be modified automatically depending on the chosen set-up, preserving the internal acoustic equipment.
SMPSAn SMPS is an electronic power supply that uses high-frequency switching and control circuits to convert electrical power efficiently. It transforms input voltage (AC or DC) to a regulated output voltage with minimal energy loss. Commonly used for its high efficiency, small size, and lightweight design.
