DB Technologies DVA T4 Active Line Array Speaker Module (B-Stock w/ Warranty)

The DVA-T4 Top is equipped with a constant directivity horn for the High and Mid section and offers a nominal coverage angle of 100å¡x15å¡. 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‰Ûªs how the effect of optimised SPL distribution is managed.åÊ

The wide frequency response from 80 - 19.000Hz and the horizontal dispersion of 15å¡ 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‰ã¢ Amplifier provides a power of 420 Watt/RMS with an efficiency of 90% and drives the system three ways active. The innovative Class-T‰ã¢ 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-breaker.

The combination of DVA S10 subwoofers and DVA T4 mid-/high-range units in a flown array packs a mighty fullrange punch with serious SPL. This setup is the preferred configuration in venues where you are unable to place bass bins on the floor or where you wish to cover bleachers or balconies.

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 16 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.
