DB Technologies DVA T 4 black
 |
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.
