DB6000-STC

Advanced Stereo and RDS Generator - BS412 Compliant

The perfect broadcasting solution

The DB6000-STC is the groundbreaking new broadcasting tool by DEVA. This is a 32bits DSP-based Stereo Generator combined with a built-in Dynamic RDS/RBDS encoder. It allows you to use both analog and digital AES/EBU audio sources and supports SNMP, RS232, UDP and TCP/IP communication protocols. Detects silence and automatically switches over to a backup source, thus ensuring a constant audio feed.

The DB6000-STC is fully BS412-compliant, making sure that you can achieve the loudness of sound that you need while retaining perfect sound clarity. It is compatible with all types of transmitters and provides the same consistent level of high-quality sound, fulfilling even the strictest customer requirements.

What makes this tool especially valuable is its ability to provide against the dead air problem. It detects audio loss and switches automatically to the alternative MP3 player whose backup audio files and playlists can be uploaded form your PC through any FTP client. Its storage capacity is 8GB.

Frequently Asked Questions
  • 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 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 support@devabroadcast.com
  • How can I access the internal storage of my Silencer and upload tracks?
    An FTP client should be used in order the internal storage of the device to be entered. For further information on how to configure a connection between the device and the FTP client refer to the next question.
    Through the use of a standard FTP client, you have the opportunity to update the backup content at will via any PC. The supported format is .m3u. An important requirement for the MP3 Player configuration is that all MP3 files should be stored in a folder named Audio (no sub-folders are allowed). The folder should be located in the root of the SD Card. The playlist file must be named playlist.m3u.
  • How should I configure the connection between my DEVA Device and an FTP Client?
    In order for a connection to be established the following setting should be applied:
    1. FTP Server Settings
    The built-in FTP Server has four important parameters that should be configured: Command Port, Data Port, User name and Password. These parameters are to be used in the FTP client’s connection configuration. Further information on how to change the FTP Server’s settings and their respective default values can be found in the device’s User manual.
    We recommend the usage of FileZilla. This is a widespread open source software distributed free of charge, hence available for downloading from the Internet.
    NOTE: The FTP Server can manage only one connection at a time. TheFTP Server works in Passive mode. Hence, the FTP Client should also be set in passive mode.

    2. IP Router and Port Translation Settings
    If the connection to the device is made through a Network address translation (NAT) router or firewall, the port forwarding feature of the router should be configured. The port forwarding is usually set in the firewall section of the router's menu. As each router has different port forwarding procedure, we recommend you to refer to its complete manual. To allow proper data flow through the router, the FTP Command and FTP Data ports should be open.
    NOTE: The FTP port numbers to be used in the port forwarding feature configuration can be found in the device.

    3. Example of FTP Client (FileZilla) Settings
    In some cases, FileZilla's "Quick connect" feature is not able to connect with the DEVA unit. That is why we recommend the device to be assigned in the program manually.
    Enter the FTP Client and go to: File > Site manager > New Site. A dialog box requiring obligatory information about the device will appear. Fill in the needed information and press "OK".
