The 25AE-70V paging horn provide economical paging coverage for 70 Volt paging systems. In outdoor factory or warehouse environments, 25AE-70V paging horns are the best method of producing understandable sound. In these environments the directional design allows the installer to focus the sound cone down aisles and toward work areas.

The 25AE-70V paging horn provides a built-in step-down transformer for use with 25V or 70V paging systems such as Viking models PA-30, PA 60 and PA-250. The transformer has a range of 5 separate switch selectable power taps, which can be used to adjust the volume of each speaker. These higher voltage distributed audio paging systems also have the advantage of being able to connect more speakers using lighter gauge wire runs while having less volume lost in wire resistance. This saves wiring costs compared to 8 ohm systems.
