Barix Extremer 500 Audio over IP Codec.

After the great success of the Exstreamer 1000 for Studio Transmitter Link applications, introduced in 2009, Barix is now announcing the Exstreamer 500. The Exstreamer 500 offers balanced analogue in & outputs, high audio quality and low latency. The Exstreamer 500 is ideal for STL where analogue audio is used.

To simplify setting up a Studio Transmitter Link, Barix is offering the Barix Reflector Service, which helps users avoid time consuming device configuration and firewall issues. The Service takes care of the complete configuration and establishes the connection: No need for a static IP address any more, or long discussions with your IT manager to open the firewall up to traffic - the Barix Reflector service handles all that. The Reflector Service is available for a small cost/channel/month.
Audio over IP encoder/decoder with balanced inputs and outputs, contact closures (input and output) and USB flash interface. Reliable architecture, low power requirements and MP3/PCM/Ethersound support.
The Exstreamer 500 is a professional IP Audio codec 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 low power, reliable architecture makes the device an ideal choice for STL applications, professional audio endpoints (with IP or Ethersound protocol) and generic audio routing applications.
