TOA's EV-20A is an all-in-one Sound Repeater that is very useful for small-scale broadcasting. Equipped with its own built-in small amplifier and speaker, it can repeatedly broadcast its sound content, and also features a human body sensor capable of initiating the broadcast automatically when someone approaches. It can record and play up to two different messages and two different types of music, and broadcast content can be added or changed easily either by analog recording or by transferring sound sources over a USB connection.
