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.
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.
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.
How should I configure the connection between DB8000 and the FTP Client?
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 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.
The FTP Server works in Passive mode and it is necessary a Wide Area Network address to be specified.
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.
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.
