Barix Exstreamer MPA400

The Exstreamer MPA400 feeds 2 – 8 Ohm Speakers and turns them into an extensive Audio over IP system. A wide variety of audio environments, such as SIP, InformaCast and Syn-Apps are supported. The codec supports PCM, AACplus, MP3, OPUS, G.711, G.722 that can be served over HTTP and RTP protocols. Audio files can be stored on the internal memory and their playback can be triggered via a simple UDP command. The MPA400 is a solid metal device, easily installed. All PoE standards are supported (up to 4PPoE) to feed the built-in 40W full digital class-D audio amplifier meeting different speaker requirements.If PoE is not an option, an external power supply can be deployed too. The device offers a modern and user-friendly web interface for its configuration. REST API to interface with third party applications is also available.
