Barix Exstreamer 500 IP Audio Codec

The Exstreamer 500 is a professional IP Audio encoder/decoder that provides balanced analog audio interfaces (stereo input and stereo output) and contact closures.

A USB flash interface allows use of external memory to store audio files. The device’s low-power, reliable architecture makes the device an ideal choice for broadcast applications such as STL, confidence monitoring, remote contribution and silence detection, as professional audio endpoints (with IP or Ethersound protocol), and for generic low-latency audio streaming and routing applications.

Features:
– MP3, G711, G.722, PCM Encoding / Decoding
– Shoutcast/Icecast Source capability
– Audio Level Supervision with SNMP Trap generation
– IP Streaming via TCP, UDP, RTP, Multicast
– Balanced Line Level Input (Stereo)
– Balanced Line Level Output (Stereo)
– Relay Output (4)
– Contact Closure Input (4)
– RS-232 / RS-485 Serial Port
– USB Flash Memory Interface
– Supply Voltage 24…48 VDC
