The DB8000 Silence Monitor is designed to eliminate the dreaded dead air problem. In case of audio loss, the unit will detect the silence and will switch directly to the AUX input or the built-in MP3 audio back-up player. The audio files and playlists can be uploaded to the device from your PC via any FTP client. In addition, the internal bass and treble control module allow advanced audio adjustment of the MP3 backup audio.

The unit has DTMF remote control features; a 3 digit DTMF tone combination can change the audio source input or start any playlist from the built-in MP3 Audio Player. The DB8000 can be used for local content or a regional advertisement spot insertion, thanks to this feature.

The DB8000 can also send e-mail notifications in case of an input signal source change. The emails are generated to a predefined recipient and contain a short text message describing the source change: Main, AUX or Backup.

The best device to fight the dreaded dead air problem is the DB8000 by DEVA Broadcast Ltd. It is designed and built to be simple, flexible, reliable and easy for integration with the existing setups: from a single station to large radio networks. The basic principle of DB8000 is that this unit can detect the silence and start playback of a preliminary created play list on the built-in MP3 player. As an addition, if power failure is detected, the MAIN Audio inputs will switch directly to the Audio outputs. Once the power is restored, the DB8000 will resume its proper operation.

The MP3 backup audio files and play lists can be uploaded in the DB8000 from your PC using any FTP client. The audio storage capacity of DB8000 is 2 Giga Bytes.

The DB8000 provides additional security in case of loss of audio at the inputs. The audio backup is presented as an integrated auxiliary audio input for external program backup audio source and built-in MP3 audio player. Internal bass and treble controls module allow advanced audio adjustment of the MP3 backup audio.

The unit has DTMF remote control features. Preliminary assigned up to 3 digits DTMF tone combination can change the audio source input or it just can start playing from the play list of the built-in MP3 Audio Player. Through this feature the DB8000 can be used for local content or regional advertisement spots insertion.

• 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 DB8000 to be entered. If you do not have one installed on your computer, we recommend the usage of FileZilla. For further information on how to configure a connection between the silencer and the FTP client refer to the next question.
  DB8000 has a built-in backup audio player. It plays tracks from SD Card storage uploaded over the FTP, in case of main audio signal loss.
  An important requirement for the MP3 Player configuration is that all MP3 files should be stored in a folder named MP3. The folder should be located in the root of the SD Card. The playlist file have to be named playlist.m3u and the file names have to be no longer than 8 symbols, followed by 3 symbols extension. For example: use track01.mp3 instead of 01_backup_track.mp3
• How should I configure the connection between DB8000 and the FTP Client?
  In order for a connection between DB8000 and the FTP Client to be established the following setting should be applied:
  1. IP Router and Port Translation Settings
  If your internet connection is going through a Network address translation (NAT) router or a firewall, the port forwarding feature of the router should be configured.
  The port forwarding can be set in the firewall section from the router's menu. As each router has a different port forwarding procedure, we recommend you to refer to its complete manual.
  To allow specific types of data flow through the router, the following ports should be open.
  

  • FTP Command Port - 21 (default value);
  • FTP Data Port - 2020 (default value).

  NOTE: If the FTP ports are different than the default ones, the same port values should be used in the port forwarding feature configuration.
  
  2. FTP Server Settings
  The FTP Server works in Passive mode and it is necessary a Wide Area Network address to be specified.
  

  • Using the navigational buttons find the 7.FTP Server Settings sub-menu and press OK to enter it;
  • Using UP and DOWN buttons move the cursor and select the parameter to be edited;
  • Press the OK button again and the editing field will start start to blink;
  • Enter the needed values using the UP and DOWN keys. To move between the parameter's fields use the LEFT or RIGHT keys;
  • Press OK to confirm the selection;
  • Exit the Sub-menu.

  NOTE: The WAN IP Address might also be changed through the DEVA Device manager.
  If DB8000 is connected to the same LAN as the computer where the FTP client is installed the WAN IP Address should match the IP Address in sub-menu 6.Network Settings (refer to Step 2).
  If a networking device (a router for example) is used, then DB8000 WAN IP Address should match the routers IP Address.
  The other two parameters that should be specified are Command and Data ports.
  NOTES: The FTP server can manage only one connection at a time. The FTP Client as the FTP Server should be in passive mode.
  
  3. FTP Client (FileZilla) Settings
  In some cases, FileZilla's "Quick connect" feature is not able to connect with DB8000. 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:
