The DB7022 – Dual Diversity DAB/DAB+ Monitoring Receiver is a next-generation tool that takes signal monitoring to another level of accuracy and dependability. It fully meets the Digital Audio Broadcasting standard and offers a combination of features that place it in a class of its own in terms of performance and quality. Most notably, it provides diversity reception which ensures a constant signal without interruptions.

DEVA has established a long tradition of bringing together robust designs and sophisticated, refined technology perfected to the minutest detail. The DB7022 is a prime example of that tradition due to a number of assets. It is an impressive dual receiver, fully compatible with the Digital Audio Broadcasting Standard (ETSI EN 300 401 DAB). It automatically displays live metadata for all standards and supports AAC, AAC+, MP3 and RTP, as well as Program Associated Data (PAD), all standard bitrates and VBR.

The outstanding feature of this tool is its diversity reception capability which offers a reliable solution to the problem of signal interruptions by ensuring that the device switches between antennas when necessary for a constant audio signal.

The DB7022 monitors and logs the signal while also measuring the DAB signal quality and the Left & Right Audio level values and storing them for future analysis. All users need in order to download the gathered data is a standard FTP client. The device provides local alarm options and online notifications via rear-panel alarm GPOs, E-mail and SNMP in case of audio loss or change in the DAB signal and the Left and Right Audio levels. Compatibility with the most popular media platforms like Icecast and Shoutcast is also a matter of course for this type of DEVA product.

The DB7022 has a user-friendly front panel menu that facilitates navigation, as well as a set of four soft buttons and a high-resolution OLED graphical display for easy parameter reading. The device can also be programmed remotely through the PC, tablet or smart phone via a standard web browser; Apple and Android devices are also supported.

Robust and at the same time easy to operate, the DB7022 is an advanced tool that provides reliable monitoring at an affordable price.
