Here are the Barix Boxes I use for all our stations.
Instreamer – IP Audio Encoder $379.00. I use this as an STL to send audio to the Transmitter or as a Monitor to send the station Modulation Monitor out.
Barix Exstreamer 100 IP Audio Stream Decoder-by-Barix $195.00 I use this to decode the signal from the Instreamer above.
Exstreamer 500 for about $500.00. This is my preferred bidirectional STL for radio stations. almost all our stations use a pair of these to get the programming from the studio to the Transmitter. The best part about these boxes is that you can insert a USB Thumb Drive into these units as a backup in the event the internet goes down. It will automatically play your audio files, Id’s etc then immediately switch back when the internet returns.
Tivoli Audio Model One M1CLA AM / FM Table Radio, Classic / Walnut for Under $150.00. If you need a super good air monitor, or EAS receiver this is the best I have found. Very sensitive, will return to the tuned station after a power interruption, has outputs and separate antenna connections. .
