Safety precautions
• Before connect or start the device, read carefully the user manual is provided, taking special care with
caution handling and the device wiring.
• The installation and rigging of the column must be done by qualified workers, following the safety rules.
• Do not clean the plastic enclosure with paint thinner or petrochemicals cleaning products.
• Do not place above the column heat sources like lighting devices, amplifiers or fogger machines.
• Do not expound the device to water splashes or rain. water inside the device can generate risk of
electric shock and can be very dangerous.
• Do not stack the columns if this installation can hurt people or destroy material goods or the device itself, in
case of fall down.
Description
The UDA 16 array system from WORK PRO is a new concept of modular column, thanks to its specifically
system of filters and its 16 transducers, this join allows to keep a tight and constant dispersion in most of its
wide frecuency response. Its vertical dispersion control means to decrease possible architectural accoustics
problems, allowing to sonorize complex rooms with possible sound problems.
The UDA 16 focuses most of the energy in the main lobe on the audience coverage preventing uncontrolled
beams that generates unwanted reflections, creating consequentially increase of the reverberation that compound
the speech. Moreover, it special design allows to reproduce a highly direcctional vertical coverage and achieve
cylindrical sound waves. The traditional sources presents 6 dB drops when the distance between the source
and the listener is double, while the directivity control can reduce this loss in 3 dB, because the UDA 16 doesn’t
disperse the energy in the vertical axis.
Main Features
Total control of vertical beam width
UDA 16 has been designed to maintain a total control of vertical beam width (one column: 22º / two columns:
11º) in almost all the reproduction band of the column (see specs). It allows to control the presence of unwanted
effects (reverbs and echos) induced by walls and ceiling reflections. UDA 16's power focuses on the area that
has to be covered, minimizing reflection (secondary lobes effects). This is particularly noticeable in reverberant
acoustic conditions, like churches, airports or train stations.
Uniform dispersion array (constant frequency response)
Each frequency reproduced by a sound source has its own directivity. However, thanks to the Uniform Dispersion
Control of the beam, it is possible to maintain constant the frequency response in a wide range of the frequency
band in the area that has to be covered.
Cylindrical waveform (Line Array effect)
The 16 transducers are placed as a line array system to create a cylindrical dispersion (waveform). The sound
pressure level only decreases around 3 dB (instead of 6 dB) each time the distance doubles (minimum loss).
As a consequence, it is possible to double the coverage for the same acoustic pressure. It also offers a more
targeted sound transmission to audience areas.
Music and speech intelligibility
By focussing the speaker sound to the audience area, UDA 16 guarantees excellent results in reverberant
acoustic conditions and, therefore, a perfect speech intelligibility. This system is perfect for location with complex
acoustics: it avoids potential reflections from ceilings and walls which makes the sound more pleasant for the
audience, with an outstanding reproduction of vocal and instruments. It is also very interesting for musicians on
stage, because they are not affected by sound reflections.
