The Hanwha Vision SPA-H100W is an all-in-one horn loudspeaker system connected by a single network cable. It's ready to deliver high-quality sound right out of the box, with no tweaking required. You can run a scheduled broadcast, background music (BGM), or text-to-speech (TTS) broadcast using each speaker on its own. You can create and schedule your own playlists from a built-in SD card or streaming services. The SPA-H100W is also great for voice announcements (scheduled or live announcements). Built-in audio synchronisation technology allows speakers to be used together.
