The UDA 16 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 16 features sixteen 2.75" diameter transducers, 0.75" voice coil, in a closed box enclosure. A proprietary IST (Interdependent Shading Topology) network has been designed to keep constant the ratio wavelength-column size, which results in a controlled 20° vertical coverage in the vocal range. This makes the UDA series 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. A wall mounting accessory is included allowing the column to be aimed up to +/- 90° sideways and from 0° to 10° downwards or upwards in two degrees steps. 

Each unit can be connected to either the input terminal strip or an NL4 Speakon. 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 16. 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.
