Fully in keeping with the high standards of the DEVA product range, the DB35 model is the very definition of reliable, high-quality streaming of the FM signal. Additionally there is an Analog AUX Input suitable for local audio monitoring. With a compact and practical, but quite elegant design, this product has been developed with the express purpose of allowing users to listen to and record the audio from any station. It also incorporates a variety of features providing accurate and dependable monitoring and measuring of signal parameters, including the RF level, Left & Right audio levels.
The DB35 boasts a fully DSP-based core and guarantees round-the-clock operation. Crucially, this product provides an analog input, which allows you to perform not only remote, but also local audio monitoring. Upon demodulation of the FM signal, the RF signal is digitized by the SDR FM tuner and all signal processing is achieved through calculations. The precision of this tool’s digital filters means that the FM signal’s Audio components can be accurately and repeatedly reproduced from one device to another, i.e. the same signal applied to two devices would give the same result. All measurement can be refreshed simultaneously and synchronously so that detailed readings of the FM Audio signal components can be obtained.
The DB35 supports TCP/IP connectivity for easy control and setup, also allowing you to monitor the channel status.
The DB35 model provides an RDS/RBDS decoder with BER meter, as well as adjustable alarms for RF Level, Left & Right Audio, Pilot Presence, RDS PI and RDS Groups via email and SNMP, while the WEB interface makes for easy management of your unit.
The DB35 brings you the customary DEVA dependability and quality. Coupled with an affordable price, all its features contrive to produce an impeccable streaming performance.
