BURGAS, Bulgaria — The DB7007 is DEVA’s second-generation digitally tuned FM re-broadcast receiver, equipped with two DSP-based FM tuners.
Upon audio loss at the inputs, the DB7007 notifies the engineering staff and switches to the second backup RF station. In case of a detected failure with the second station the DB7007 shifts to a designated IP stream or MP3/AAC back-up audio source player. The backup source priority is user-defined. The audio files and playlists can be uploaded in the device’s internal memory from a PC, via any FTP client.
The DB7007 has an easy-to-read, high-resolution OLED graphical display, front-panel alarm indicators and bright bar graphs with up to 40 LED segment indicators that allow reading at a glance of the MPX, left and right audio and the RF level. The RF (IF) signal is digitized as soon as it enters the device, and signal processing is then made through DSP algorithms, guaranteeing measurement reproducibility over time. The IF bandwidth filters ensure signal selectivity.
The RDS information contained in the processed MPX signal is displayed as RDS/RBDS data and detailed RDS/RBDS statistics. The band analyzer presents an overview of available FM signals, plus the RF signal strength. Scans can be performed within any section of the FM band in four frequency steps. A spectrum diagram displays the relation RF level vs. frequency.
The DB7007 can be also controlled through the built-in Web server with a standard browser used to monitor the status or to make any adjustments.
