General Information
Continuing a tradition for products brought about by creative thinking and technological precision,
the DB46 – Compact DAB/DAB+ Monitoring Receiver slots in seamlessly within DEVA’s range
of monitoring tools by offering another dimension of accuracy and cost-effectiveness. While also
retaining the defining characteristics of the DEVA brand, this revolutionary product is specifically
dedicated to one of the major areas in the industry - Digital Audio Broadcasting, and fully meets
the ETSI EN 300 401 DAB standard.
Along with the guaranteed quality of performance, a crucial asset of this product is its design
– compact, smart and extremely practical. Proving that practicality does not come at the cost of
efficiency, the DB46 boasts a wealth of capabilities and superb features. It has a highly-selective
DSP-based tuner, supports the latest DAB & DAB+ standards.
What is more, it offers support for Program Associated Data (PAD), as well as all standard
bitrates and VBR, and automatically displays live metadata. While the signal is being monitored
and logged, the DB46 measures the following DAB signals: RSSI, SNR, CNR, FIC Quality, FIB
Errors, FFT Offset and the Left & Right Audio level values and stores them, thereby allowing
for future analysis. A standard FTP client is all that is required for the collected data to be easily
downloaded.
The BandScan function of the DB46 presents an overview of all DAB/DAB+ signals available,
plus their RF signal strength. BandScans are possible within any section of Band III. The generated
spectrum diagram shows the RF Level vs. the channels.
Another impressive feature of the DB46 is the fact that the tool guarantees no interruption
of the broadcast signal. This is achieved through the provided local alarm options and online
notifications via rear-panel alarm GPOs, E-mail and SNMP in case there is audio loss or change in
the DAB signal and the Left and Right Audio Levels. This allows for a fast response on the part of
the maintenance staff so that prolonged signal loss can be prevented.
Users can also easily control and set up their DB46 unit remotely through their PC, tablet or
smart phone via a standard web browser; iOS and Android devices are also supported.
Compact and affordable, with a remarkable set of technical characteristics, DEVA’s DB46 is a
definite must-have for accurate, dependable DAB/DAB+ monitoring.
