IP Former TPA400 – Plenum Rated per UL Standard 2043

IP Audio Decoder, PoE powered with up to 6W amplified output on screw terminal block to drive loudspeakers

The IP Former can be attached to any loudspeaker either while in production or in existing installations. It enables audio-streaming over the internet with a reliable, fast-reactive connection, storing capabilities and VoIP/SIP negotiation. Installers can just sell an upgrade to existing installations and setups. Producers can offer an IP speaker without additional R&D. Powered by PoE, it is as easy to install as any clever IP speaker. As a decoder it streams audio from radio stations, telephones and paging stations. It is ideal for speakers to play background music, live announcements in schools, retail, offices, for emergency warning systems or triggered message playback and announcements over SIP. For management and advanced functions, the IP former is ready for (optional) sound detection of the surrounding. Barix is offering adaptation to your business needs to grow together.
