UDA SERIES: UDA 8, UDA 16
USER MANUAL
VERSION 1.2

1. OVERVIEW

The UDA 8 and UDA 16 are high output, full range, frequency shaded passive column 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 8 and UDA 16 feature eight and sixteen 2.75" diameter transducers respectively, 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 8/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.
