DSP-based FM Radio Re-Broadcast Receiver with TCP/IP Connectivity
The DB7000 possesses an advanced and highly selective DSP-based FM tuner. Any challenging problems with adjacent-signals are easily eliminated via the used high-accuracy, DSP-based IF bandwidth filters. As is required from such high-class equipment, the DB7000 measures all the important parameters of the FM transmissions.
The device is supplied with a built-in monitoring system, generating automatic warning messages in the case of out-of-limit parameters. Also, in case of an alarm event, the DB7000 will notify the maintenance staff and will switch automatically to the backup station. Thus, audio loss for extended period if problem with the main station is evident will be prevented.
An impressive additional feature is that the RDS information contained in the processed MPX signal is captured as RDS/RBDS data with detailed statistics, ensuring a complete data display at a glance. Notably, the USB and LAN communication interfaces allow flexibility for local and remote connection and control of the unit.

DB7000 is a frequency-agile, digitally-tuned FM Re-Broadcast Receiver equipped with a sophisticated and high-selective DSP based FM-tuner. The RF (IF) signal is digitalized as soon as it enters the device and all signal processing is then made through DSP algorithms. The signal being digitalized in this way, at the input, the equipment acquires measurement reproducibility over time. The high-accuracy DSP based IF bandwidth filters help to solve difficult adjacent-signal. The DB7000 measures conveniently all important parameters of FM transmissions. The built-in monitoring system will generate automatic warning messages in case of faulty or missing data. The incredible processing power of the device enables all measurements to be refreshed simultaneously and synchronously, thereby allowing for detailed readings of all the Multiplex FM signal components.
Another impressive addition to DB7000’s features is the backup station. In case of an alarm event, the unit will not only notify the maintenance staff but will also switch automatically to the backup station once the event is registered. Thus, audio loss for extended period if problem with the main station is evident will be prevented.
The DB7000 has an easy to read, high-resolution OLED graphical display and ultra-bright alarm indicators that allow reading the signal at a glance. An additional feature to the list of DB7000 characteristics is that the RDS information contained in the processed MPX signal is easily visualized and represented as RDS/RBDS Data and detailed RDS/RBDS Statistics. The DB7000 is designed to support USB and LAN communication interfaces, allowing flexibility in remote connection and control of the unit. Easy channel status monitoring or audio listening from everywhere is possible through your mobile phone. With the Audio Stream Server you can listen to the audio of the received radio program.
The Band Analyzer function of the DB7000 presents an overview of all FM signals available, plus the RF signal strength of these stations. Scans are possible within any section of the band in the FM band in 3 different modes. The generated spectrum diagram shows the RF Level vs. the Frequency. Scheduled Band Scans can also be enabled for RF intruder or pirate transmissions detection. In case of a transmission failure, maintenance staff will be immediately alerted via E-mail, SNMP, or SMS which signals the technicians to restore a normal service as soon as possible. A high performance level and sustained reliability make the DB7000 to satisfy the requirements of the most demanding broadcasters, as well as the satellite and cable operators. This product has been designed with the latest state-of-the-art audio technology in use, and with very low harmonic distortion!

How can I lock the front panel keyboard?
To prevent unauthorized local access, the unit offers password protected keyboard locking. By default the keyboard is unprotected. To enable this function, using the front panel navigational menu, go to Settings > Security > Front Panel, then press OK and ENABLE the Access Control function. Set the preferred 4 digit password and access timeout.
Once the keyboard lock function is enabled, every attempt to use it will require a password: ENTER PASSWORD:0***. Access will be denied upon false entry.
How to unlock the front panel keyboard? I have forgotten the password / I have enabled the function unintentionally.
If the “Keyboard unlock” function has been activated by mistake, try to unlock it using the default password 01234. In order to deactivate the code protection, once the front panel menu is unlocked follow the menu path Menu > Settings > Security > Front Panel > Access control and then select Disable.
If you do not manage to unlock the front panel with the default password, nevertheless whether it has been changed intentionally or not, the unit should be returned to its factory defaults in order for the password security to be disabled.
I forgot the master password for the DEVA Device Manager Software, what should I do?
If due to any reason you have forgoten your Master Password, contact us at email@example.com for detailed instructions on the reset procedure.
I have forgotten my password for the WEB Interface. What should I do?
The WEB Interface password could be viewed/changed via the front panel navigational menu. The menu path is Menu > Settings > Security > Remote Access.
I have forgotten both – the front panel and WEB Interface passwords. What should I do?
If due to any reason you have forgoten both passwords - the one for the front panel and the one for the WEB Interface, please contact us at firstname.lastname@example.org
How can I switch between %/KHz (RDS/RBDS Mode)?
The mode could be changed via the front panel menu and via the WEB Interface.
The menu path when the WEB Interface is used is : Settings > Tuner > section “ RDS/RBDS Mode”.
The menu path when the change is made via the front panel menu is: Settings > Tuner > RDS Mode.
I cannot receive E-mails from the monitoring equipment. How can I configure the E-mail client?
The unit should be configured according to the e-mail provider’s specifications. Otherwise, messages to your e-mail account will not be received. The configuration is made through the WEB Interface, Settings > Comm > E-mail section.
Enter the desired alarm recipients in e-mail 1 and/or e-mail 2 fields. Fill in your e-mail account settings: Sender, Username and Password, Server, SMTP port and connection type. You can also change the host name if necessary or otherwise leave it as it is.
We recommend you to use the ‘Test’ button and generate a test e-mail, which upon success will be delivered to the specified E-mail 1 and/or E-mail 2.
Example of Test E-mail Message:
DB7000 Test Message. Please do not reply to this e-mail.Note that the “Network” section should also be correctly configured, most importantly the “DNS” parameter if you want to use server names (ex: “smtp.yourdomain.com”).
I cannot receive SMS from the monitoring equipment. How can I configure the GSM modem?
First, you will have to make sure that the GSM modem is properly connected to the device.
Then enter the device via the WEB Interface and go to Settings > Comm > GSM Modem section. Check the baud rate, as it is mandatory for the proper operation of the GSM Modem. You will also have to make sure that the PIN security of the used SIM card is disabled.
If the above conditions are fulfilled you could proceed with the next step. Up to four numbers for SMS alarm notifications could be set. We recommend a test SMS to be generated (via pressing the ‘Test’ button), once all needed settings are applied. Upon success, the SMS will be delivered to all specified GSM numbers.
Example of Test SMS Message:
DB7000 Test Message.The current condition of the GSM Modem could be checked in the “Status Screen”.
I do not hear the audio from the ‘Listen’ button of the WEB Interface.
Please verify that your speakers/headphones are connected and the audio is not muted. Also, there is some buffering performed by the web browser before the audio starts. This process may take about 20 seconds or more for some browsers. Another important condition is that the connection bandwidth should be high enough; otherwise the audio will skip or become choppy.
