UDA SERIES
UDA 1, UDA 2, UDA 4 www.workpro.es 4
1. OVERVIEW
The UDA 1, UDA 2 and UDA 4 are high output, full range, passive speakers which provide voice
intelligibility and musical clarity in acoustically challenging environments such as shopping malls, houses
of worship, restaurants, congress halls, hotels, airports, train stations, swimming pools, conference
rooms or museums, where reflective surfaces create a reverberant sound field.
The UDA 1, UDA 2 and UDA 4 feature one, two and four 2.75" diameter transducers respectively,
0.75" voice coil, in a closed box enclosure. Its sonic characteristics make this UDA models suitable to
be installed in rooms with problematic sound reflections where vocal intelligibility is paramount.
The narrow extruded aluminium enclosure has been designed for a seamless visual integration in every
venue and is available in black or white finish. The grille is also made of aluminium and internally
covered with a protective water repellent fabric which prevents splashed water and dust from damaging
the transducers, featuring thereby an IP 65 protection rating. Two wall mounting accessories are
included. Wall 4V allows the enclosures to be aimed up to +/- 50° horizontally and up to +/- 30°
vertically. Wall 4H allows the enclosures to be aimed up to +/- 50° sideways only.
Each unit can be connected through an input barrier terminal strip. Connections are protected by a
metallic weather resistant cover featuring a cable gland on the bottom which prevents water or moisture
from causing a shortcircuit.
The accessory UDA 16 TL (not included) allows for high impedance connection of the UDA
loudspeakers. It houses a high quality 120Wrms@100V line transformer (60Wrms@70V) that makes it
suitable for installations where long cables have to be deployed.
Tuning presets are available to enhance the frequency balance and intelligibility.
