AxelTech Lynx
Lynx is an evolved Broadcast Digital FM Tuner, designed for receiving, monitoring and listen to FM radio signals. The built in web interface allow multiple users to display all the parameters and details of the incoming signal. The tuned audio frequency is available on the analog balanced output (XLR), on the digital output AES/EBU (XLR), on the headphone output and via IP streaming. At the same time. The quality and accuracy of the built-in tuner allow a very strict analysis of the tuned frequency, modulation and the RDS data decoding.
