OPTIMAL AUDIO UP 4O
Full-range, open-backed, 4” ceiling speaker
Up 4O is a discreet 4” ceiling speaker delivering consistent coverage and crisp, clear sound to a wide range of cost conscious, commercial environments — from hotels and concourses to retail outlets, bars and restaurants.
Up 4O is supplied without a back can for ceilings with a minimum cavity depth, while an integral fixing system is included to achieve a simple and clean installation. The steel perforated grille a is finished in neutral white.
Up 4O features a 4” (105mm) driver which is ideal for both music and speech reproduction. A 130° conical coverage pattern ensures the system is delivering sound where it needs to go.
Each Up 4O has been specifically designed to run on 70 or 100 volt line systems.
SmartAmps or Zone will provide optimal performance and loudspeaker protection. When coupled with the Zone series, a ZonePad and the WebApp makes setting up a system and end user control simple and intuitive.
