The 300AE Paging Horn provides a direct voice coil connection for use with 8 Ohm paging systems such as Viking models PA-2A, PA-15, HF-3W, DVA-2WA and M2W. Even though its 30 Watt rating is greater than these lower power paging amplifiers provide, the 300AE is an excellent choice because it is more efficient than Viking's smaller 25AE paging horn. In other words, the larger 300AE only needs 1 Watt of power to play as loud as 2 Watts being driven into the smaller 25AE paging horn.

The 300AE paging horn also provides a built-in step-down transformer for use with 25V or 70V paging systems such as Viking models PA-30 and PA-60. The transformer has a range of power taps that are selectable with a 6 position rotary switch, so that installers are able to independently adjust the volume of each paging horn. These higher voltage paging systems also have the advantage of being able to connect more speakers using lighter gauge wire runs and still have less volume lost in wire resistance.

The weather resistant design of the 300AE allows for use in outdoor, factory, or warehouse environments. Its larger size and greater frequency response provide greater intelligibility of voice pages and is suitable for background music. The directional design allows the installer to focus the sound cone down aisles and toward work areas. The included mounting hardware provides full adjustment of horizontal and vertical positioning.
