General Information
Reliable, easy to manage and fully compliant with the Digital HD Radio Broadcasting standard,
the DB37 brings together a dependable streaming functionality and practicality at an aordable
price. One of its dening assets is its highly-selective DSP-based tuner, which allows the HD Radio
Broadcast and FM station to be selected, listened to and recorded. Additionally, the dedicated
hardware will let you constantly monitor the sound of your station and will also measure and store
for future analysis the RF level and Left & Right Audio Levels. For an even better performance,
the DB37 comes with a built-in FM RDS/RBDS Decoder and HD Radio PAD Decoder.
Crucially, this product provides an analog input, which allows you to perform not only remote,
but also local audio monitoring. Users can also toggle through the FM and HD Radio broadcast
stream to conrm audio presence and quality in live broadcast environments.
Another great feature of the product is the WEB interface, which guarantees easy remote setup
and control. The setup and control of the unit could be done through your PC, tablet or smartphone,
via a standard web browser. All operating systems are supported.
DB37 oers a great combination of reliable HD Radio streaming and an aordable price.
