Exstreamer provides up to 40 watts RMS audio output to low impedance speakers while integrating them into AoIP systems.
Zurich, Switzerland (March 10, 2022)—barix unveiled the Exstreamer MPA400 IP audio decoders and amplifiers for applications ranging from emergency notifications to paging and background music.
The new hardware supports a variety of codecs and provides up to 40 watts of audio output for two to eight ohm analog speakers, enabling the integration of existing speakers into audio-over-IP systems.
The Exstreamer MPA400 can decode audio streams streamed via HTTP or RTP protocols into codec formats such as PCM, AACplus, MP3, Opus, G.711 and G.722. Pre-recorded audio files can also be stored in the device’s internal memory for triggered playback.

Native support for Singlewire Informacast and Intrado Revolution systems enables Exstreamer MPA400 devices to integrate connected speakers as endpoints for enterprise-grade mass notification solutions. SIP support (including Secure SIP) enables compatibility with VoIP phone systems and direct addressing of each MPA400 device. Tiered source stream prioritization – configured via the device’s built-in web interface – allows emergency notifications or urgent pages to automatically replace background music and other audio elements.
Alternatively, the Exstreamer MPA400 can be configured as a dedicated AES67 receiver/decoder, enabling interoperability with Dante-enabled devices and AES67-based audio over IP networks.
Support for multiple Power-over-Ethernet (PoE) standards allows input audio streams and power to the Exstreamer MPA400 to be carried over a single cable while meeting different speaker requirements . Up to 40W RMS output at four ohms is available when powered by IEEE 802.3bt (PoE++ or 4PPoE) or an external power supply. 20 W RMS is available with IEEE 802.3at (PoE+) or 10 W RMS with IEEE 802.3af (PoE).
The Exstreamer MPA400 is expected to start shipping in April.
