Barix STL

Studio Transmitter Link

The Barix Studio Transmitter Link (STL) Application is a fast and reliable solution to stream audio in full-duplex PCM and half-duplex MP3 from a broadcast studio to a transmitter device in another physical location. RTP over UDP protocol guarantees low latency and strong reliability of the audio stream. The application can stream to eight unicast or multicast destinations, or can send as a broadcast. Several administration tools like keep alive handshake, contact closure tunneling, SNMP traps, Serial gateway, multicast and DNS are supported. The integrated Reflector Server Software simplifies connectivity over the Internet when no fixed external IP address is available. The Barix STL Application is a very powerful and flexible tool for a professional radio distribution.

What Others are Saying about Barix STL

"I chose the Barix Instreamer and Extreamer 110 because of the economical price and functions that I needed. I use this pair as an Studio Transmitter Link for a radio station in Peru, South America. They have been extremely reliable and I especially like the relay contact on the Extreamer. I use it to control a contactor to turn on the transmitter and associated equipment when streaming begins."
