The UDA 4 is a high output, full range, frequency shaded passive column speaker which provides 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 4 features four 2.75" diameter transducers, 0.75" voice coil, in a closed box enclosure. This makes the UDA 4 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 enclosure to be aimed up to +/- 50º horizontally and up to +/- 30º vertically. Wall 4H allows the enclosure to be aimed up to +/- 50º sideways only
Each unit can be connected to either the input 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 4. 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.
