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.

Equipped with top-notch features and engineered for maximum versatility, the DVA T4 delivers premium performance and ensures excellent return on investment.

Full of Technology:

  • Modules (meter array) connected to one 16A phase
  • Place just 125Kg 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 on board
  • For utmost operating safety

Key Features

Active Line Array 420 Watt RMS
The DVA T4 is equipped with unique digital power amps that provide a total of 420W RMS. Driven by Digipro® technology, their resolution is several-fold that of conventional digital amps.

They render signals very accurately with this high-definition audio capability.
Sonic images are almost impossible to distinguish from those of analog sources, even in the HF range. The amps are equipped with high-quality delta-sigma converters.

The DVA T4‘s digital power amp features DPP™ (Digital Power Processing) technology and a multiband compressor/ limiter with separate response curves for each signal path. Its dynamic range is exceptionally wide.
For example, headroom in the middle and high-frequency bands ranges up to 22dB.
This innovative circuitry not only maximizes dynamic response, it also ensures signals are rendered accurately and uniformly even at threshold levels.

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.

High Efficiency:
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.

State-of-the-Art Drivers:
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.
This driver was specially designed for the use with Line- Arrays. Its compact measurements allow very close proximity which is a main factor for minimum interference.
