Please specify DPC-15, or C01 A three-way active line array system, the DVA T4 has set new standards in the sound reinforcement industry since its 2007 market launch. Better yet, it has brought the benefits of real line array technology to a much wider range of users. More than 15,000 DVA T4 modules have shipped as of February 2011. Equipped with top-notch features and engineered for maximum versatility, the DVA T4 delivers premium performance and ensures excellent return on investment. • 8 modules (2 m array) connected to one 16A phase place just 125 kg load on the pick-point • Fully powered units, freely scalable to setups of any size • Lossless signal path with no need for speaker cables • None of the impedance and amp channel availability concerns associated with passive models • Sequentially configurable array segments • Digital controller (DSP) onboard for utmost operating safety The future of line arrays is active Beside the accurate reproduction of a 3-way system with active DSP controlled amplification and all other advantages of active technology like phase- and line alignment, the active technology gives the advantage to optimize each Array-element due to its position in the system and the total number of combined line array units. The DVA T4 provides 8 different Setups to optimize for example the HF-response according to it's function (nearfield/midfield/farfield) or the low-mid-response due to the number of combined units. No lossfull and expensive speaker cabling is needed anymore. Constant directivityThe DVA T4 Top is equipped with a constant directivity horn for the High and Mid section and offers a nominal coverage angle of 100°x15°. The CD-Horn provides high flexibility and a good natured attitude if for instance the Array is not aligned correctly. The DVA uses apart from the formation of cylindrical waves (very much depending on the number of T4 elements) the vector summing of the individual horns. This means that with growing distance to the source (if set up correctly) the listener perceives more and more vector sums of the single elements. However it has to be considered, that the fewer elements are used to spread the sound to a specific area, the stronger must be the curving of them. That’s how the effect of optimised SPL distribution is managed. The wide frequency response from 80 - 19.000Hz and the horizontal dispersion of 15° offers flexible handling without additional Subwoofer e.g. for background-music and speech. For other applications like live music the matching Subwoofer SUB S20 can be added to the system. The integrated digital Class-T™ Amplifier provides a power of 420 Watt/RMS with an efficiency of 90% and drives the system three ways active. The innovative Class-T™ design offers in comparison to other digital amplifiers an outstanding sound quality with superb high-frequency sound, equal to a Class A/B circuit. The integrated 24-Bit DSP operates the active crossover, the active EQ, the Limiter-control and all safety-circuits. In addition to that, the DVA T4 is equipped with an innovative power-factor-corrected power supply, operating from 85 to 260 V which allows up to eight DVA T4 to be connected to one 16 amp AC-braker.
