IP Former TPA400
IP Speaker Amplifier

The IP Former now supports AES67 which allows the IP Former to be used as a Dante™ end-point, turning almost any speaker into a Dante enabled speaker. Playout synchronisation allows multiple speakers to be used in the same room when RTP (Real-time Transport Protocol) sources are used.

The IP Former converts existing passive loudspeakers to network loudspeakers in various applications. It is a solid metal device that is mounting compatible to 70/100V Speaker Transformers and can therefore be mounted to any existing Speaker. A wide variety of Audio Systems, such as SIP, InformaCast and Syn-Apps are supported. Note that the InformaCast version includes a one off licence fee. The InformaCast version of the IP Former TPA400 is the BX-BAR20209301

Codecs include PCM, AACplus, MP3, OPUS, G.711, G.722 that can be streamed using HTTP, RTP or UDP. Audio files can be stored on the internal memory and played via simple UDP command. The built in 8W full digital class-D audio amplifier provides high quality audio signals to a 4 or 8 Ohm in-wall, in-ceiling or tabletop speaker. The device is powered without any other cabling using Power over Ethernet (PoE). Configuration of the device is done via the internal web interface.
