The long years of experience at the top level of broadcasting technologies, as well as the undisputable expertise of our engineering team have brought forth a brand new audio processing tool - the DB6400 FM and Digital Radio 4-Band Audio Processor.

The much-anticipated DB6400 is an innovative tool with an ultra low latency DSP-based design for unrivalled quality of sound. It has a built-in IP Audio Player which supports MP3 and PCM audio formats, as well as a fully dynamic RDS/RBDS encoder. Solves the dead-air problem by switching over to a backup source and sending an email notification.

The DSP-based Stereo Encoder in DB6400 guarantees precision of the MPX signal with advanced peak control and two independently-configurable composite MPX outputs. The DB6400 offers perfect audio clarity no matter what the source material is. A complete processing architecture: Wide band AGC with “Intelligent Gating”, 4-band Parametric EQ, Advanced Bass and Treble Controls, 4-Band High Quality Sound processor with Fidelity control and Sound Impact, 4-Band Limiter, FM Limiter with advanced distortion & pre-emphasis control and HD Lookahead Limiter.

The long years of experience at the top level of broadcasting technologies, as well as the undisputable expertise of our engineering team have brought forth a brand new audio processing tool - the DB6400 FM and Digital Radio 4-Band Audio Processor.

Another feature that distinguishes the DB6400 from other products of its category is its Fallback function. This cutting-edge device is able to detect signal loss. In the case of silence at the main audio input, it automatically switches over to a backup source, thus ensuring a constant audio feed. What is more, an email notification is immediately sent which allows for an instant response on the part of your technical support team. Through the use of a standard FTP client, you have the opportunity to update the backup content at will via any PC. An additional asset is the automatic return to the main audio source as soon as the default input is restored. All silence sense parameters are user-defined.

Needless to say, the DB6400 comes with a user-friendly, comprehensive and well-organized user interface. Access is available through the front panel, remotely via TCP/IP and by using the WEB interface through iOS, Android or any other mobile device.

This one-of-a-kind device is the peak of DEVA’s engineering achievements combining simplicity of use, affordability of price and top performance and employing an array of technical parameters not found in any other device of its class.

• 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".
  
  Select "Transfer Settings" sub-menu and apply the settings as shown below:
