Overview:

The DB Technologies 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.

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 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.

CONTROLS AND FUNCTIONS

1) POWER SWITCH - This switch permits turning the speaker on and off.

2) "MAINS FUSE" FUSE CARRIER - Mains fuse housing.

3) "MAINS INPUT" POWER SOCKET - For connecting the power cable provided. The connector used for mains connection is a POWER CON® (blue)

4) “MAINS OUTPUT LINK” RELAUNCH POWER SOCKET - For relaunching the mains power. The output is connected in parallel with input (3) and can be used to power another amplified speaker.  The connector uses a POWER CON® (grey)

5) " BALANCED INPUT” INPUT CONNECTOR - Balanced input at line level. It is able to accept “XLR” sockets.

6) "BALANCED LINK/OUT ” OUTPUT CONNECTOR - The “XLR” connector connected in parallel with input (5) can be used to send the  input audio signal to another amplified speaker.

7) “INPUT SENS” INPUT SENSITIVITY CONTROL - This control regulates the sensitivity of the signal amplifier input. This control does not affect the “BALANCED LINK/OUT” output level

8) “LIMITER” INDICATOR LIGHT - This indicator comes on red to indicate that the internal limiter circuit has tripped. This prevents amplifier distortion and protects the speakers against overloads.

9) “SIGNAL” INDICATOR LIGHT - This indicator comes on green to indicate the presence of the audio signal (at a level of -20dB).

10) “MUTE/PROT” INDICATOR LIGHT - This yellow indicator indicates amplifier status. In normal operating conditions, the LED is off; if it flashes or is always on, refer to the diagnostics table to check amplifier status.

11) “READY” INDICATOR LIGHT - This indicator comes on green to indicate that the main power voltage is correct. In normal operating conditions, the LED is on; if it flashes or is off, refer to the diagnostics table to check amplifier status.

12) “SET-UP MODE” EQUALIZATION SWITCH - This 10-position rotating switch permits selection of the equalization curve according  to installation type.
