dB Technologies DVA T4 3-Way Active Line-Array Module with CO1 Power Cable, 80-19.000Hz Frequency Response, 128dB Maximum SPL, 420W RMS, White

The dB Technologies DVA T4 (White) 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.

Reliability
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.

Constant Directivity
The DVA T4 Top is equipped with a constant directivity horn for the High and Mid section and offers a nominal coverage angle of 100deg.x15deg.. 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 optimized SPL distribution is man.

Ground stacking
T In case there are no possibilities to fly the system or the ceiling of the venue is not high enough, the DRK-10 can be used for ground stacking too. A special bracket provides an inclination up to 7.5deg.. The DRK-10 fits exactly onto the surface of an upright positioned DVA S20 subwoofer and can be mounted by two quick release pins on top of the sub. The combination of a DVA S10 subwoofer and a DSA-4 pole mount adaptor holding up to three DVA T4 mid-/high-range units is a great solution for smaller applications and for delay zone sound reinforcement. The continuously adjustable DSA-4 adaptor lets you aim the mid-/high-range units.

Flying the cabinets
The DVA T4 comes with precisely engineered flying hardware. The hardware in combination with the extremely low weight of a T4 top allows easy and fast setup of the whole system. The curving can be adjusted in steps of 2.5deg. within a range of 0deg. and 15deg.. For an optimum of performance the system should be principally flown. The DRK-10 flying frame holds up to 16 T4. For professional handling the frame is well balanced and the angle of inclination can be corrected with the upper rear flying rails. The DSA-4 adapter attaches to the bottom cabinet and secures the rig to the truss with half-couplers and a pipe. They recommend using this adapter to prevent the stack from twisting and swinging. The combination of DVA S10 subwoofers and DVA T4 mid-/high-range units in a flown array packs a mighty full range 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.

Handling, stacking and flying the DVA T4
The DVA T4 Line-Array element has a sensational weight of only 13.8kg. 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 100 kg.
