General Information

Fully in keeping with the high standards of the DEVA product range, the DB35 model is the

very denition 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 digitalized by the SDR

FM tuner and all signal processing is achieved through calculations. The precision of this tool’s

digital lters 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

aordable price, all its features contrive to produce an impeccable streaming performance.
