Since the 90’s the Line-Array technology has changed soundreinforcement drastically. The vertical arrangement of speakers in an enclosure offers a high influence to soundspreading and reduces in comparison to ordinary soundsystems the loss of signal in relation to distance combined with a slim structure and broad sound distribution.
DVA makes this technology, which up to recently was only provided in high profile projects and installations, available for a broad range of budget orientated applications. All relevant criteria like weight, acoustic handling including purchase price and additional costs in form of transport and flying accessories have been well considered. Despite above mentioned features, the DVA is not limited in terms of curving and maximum amount of possible Array-Elements, like products of competitors in recent history in this segment. Specially the individual curving, optimised to the demands of the event, enables the acoustic advantages and shows the flexibility of DVA.
dBTechnologies designed a Line Array which sets new standards in handling, flexibility and profitability by using most modern technology and materials, with a vast amount of knowledge and experience in building active loudspeaker systems. The DVA T4 Line-Array element has a sensational weight of only 13,2kg. The obvious advantage for handling and transport also makes flying possible where under normal circumstances the trussing is not strong enough to support also flying of the audio devices - an Array of six T4 Tops therefore weighs less than 120 kg.
The 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.
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 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.
