DESCRIPTION
The speakers DVA M2M and DVA M2S are part of the modular system called DVA MINI.
The system can be used in ground stack configuration or suspended in line-array configuration.
The modules use a fast, innovative mechanical fastening method.
This series is ideal for installations in theatres, places of worship, convention centres, concerts and
live music performances which require medium-high sound pressures and limited weight and
footprint.
DVA M2M is equipped with two class D amplifiers series DIGIPRO
speaker DVA M2S thanks to a simple, easy wiring.
The amplifier module is capable of delivering 400W RMS (total), 200W RMS for the bass section
and 200W (RMS) for the treble section.
The high efficiency of the modules DIGIPRO
weight and footprint. Thanks to its low power dissipation, the cooling of the amplifier module takes
place in a static manner, avoiding the use of fans.
The digital pre-amplifier with Digital Signal Processor (DSP) manages the acoustic components,
the frequency response, the limiter and the speaker alerts.
The SMPS (Switched-Mode Power Supply) Power Supply Unit (PSU) thanks to its self-range
technology ensures operation at supply voltages from 100V~ to 120V~ and from 220V~ to 240V~.
Both speakers are provided with the same acoustic components.
The bass section is composed of two 6.5" neodymium woofers
(voice coil 1.5"). The double phase plug in front of each individual
cone avoids horizontal phase overlapping increasing efficiency and
directivity. The double phase plug present in front of each individual
cone brings nearer the point of release of the woofer acoustic
avoiding the overlap of the horizontal phase.
The design of the phase plugs allows the proper matching with the
speakers of the series DVA Mini.
DVA M2M and DVA M2S are made of polypropylene with two rear side handles to facilitate
transport and installation. The speakers are equipped with steel brackets and an easy, simple
locking system.
The rear bracket is graduated (0°-1.5°-3°-4.5°-6°-8°-10°-12.5°-15°) to allow fastening various
speakers with the desired angle.
The accurate design enables to achieve a constant and precise
coverage of 90° horizontally and 15° in the vertical direction for each
speaker.

The treble section consists of two 1" neodymium compression
drivers (voice coil 1") mounted vertically and spaced to optimize
vertical coverage.
The horn has been specially designed for the proper matching of the
speakers of the series DVA Mini.
