Product Details


The IP Former TPA400 (Barix IP Speaker) converts traditional speakers to IP speakers for various commercial IP audio applications. This product is a robust device with a solid metal housing, and when added / connected to any 2, 4 or 8ohm speaker, conversion to an IP speaker is completed.

Use the IP Forma IP speakers to create Background Music (BGM), Tannoy/Paging/Public Address (PA), triggered message playback and SIP Telephony announcements.

IP Former TPA400 has also been specifically designed so that the mounting holes are compatible with many 100V speakers and their transformer mounting holes. As a result, a 100v speaker transformer can be removed and replaced with the IP Former to create an IP speaker.
