The 30AE-70V paging speaker provides economical paging coverage for 70 Volt paging systems. In office and restaurant environments, it is best to distribute sound more evenly. Ceiling mounted 30AE-70V speakers in close proximity offer the best distribution and are cost effective. The 30AE-70V ceiling speaker 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 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.
