DB8008

Digital Silence Monitor with MP3 and IP Audio Backup Players

Flexible, Reliable, Easy Configurable

DEVA’s DB8008 is a flexible and reliable tool, designed by our engineers specifically with the aim of solving one of the most significant problems in the radio industry – the one of radio silence. DEVA’s smart and highly practical solution detects signal loss and immediately switches the output to one of two alternative built-in backup players – MP3 or IP Audio. As an additional advantage, it can be easily integrated into the existing setups of a single station and large radio networks alike. It features a fully DSP-based core, professional AES/EBU digital audio inputs and outputs, and additionally allows for TCP/IP remote monitoring and control via SNMP and the WEB Interface. MP3 backup audio files and playlists can be uploaded to the device using any FTP client, while the audio storage capacity of the unit is an impressive 2GB for over 24 hours of audio playback without repetition.

Frequently Asked Questions
  • 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 Main menu > WEB Server.
  • I want to configure DB8008 to work with our Icecast Source Client. How can I do that?
    Prior to implementing the below written adjustments, the following conditions should be fulfilled:
    • DB8008 should have a static IP Address. If the device is placed behind a router, you will have to make sure that the Icecast Player server port is properly NAT forwarded;
    • On the other side, of the connection, there should be an encoder (for example DB9000-TX/DB90-TX) set as Icecast Source Client or other Icecast Source Client.

    The Icecast in DB8008 acts like a server. The audio stream is received from Icecast source client, for example DB9000-TX or DB90-TX. In this configuration, the Icecast source client initiates the connection.
    If DB8008 will use an on-line radio, IP Audio should be used. The IP Audio Client in DB8008 acts like an Icecast player. The audio stream is received from the Icecast server. In this configuration DB8008 initiates the connection.

    Once one of the above cited conditions is implemented, the following settings should be made:
    • Configure the Icecast source client to connect to DB8008's Icecast port, 5555 by default;
    • Configure the Icecast source client to use the user name and password set in DB8008 Icecast settings, source and pass by default.
  • How to connect DB8008 to our Icecast/Shoutcast compatible online radio?
    One of the following conditions should be fulfilled, prior to applying any adjustments:
    • An encoder (for example DB9000-TX/DB90-TX) with static IP Address and properly configured Stream Server could be used.
    • An online radio could be used.

    Once one of the above cited conditions is implemented, the following settings should be applied, via the WEB Interface:
    • Go to Configuration > IP Stream;
    • In IP Audio Client section - URL of the Server should be specified. The URL is a mandatory requisite needed in order for a connection with the server to be established. The URL could be compounded of a domain name or IP Address, Server Port, and path (optional), ex. radio.myserver.com:5000/live or 192.168.120:5000;
    • Choose the preferred decoder, prebuffer and specify buffer timeout. If needed set new gain adjustment settings.
    • From the Audio Section set the priority of the IP Audio Client.
  • How can I stream RTP audio to DB8008?
    Prior to implementing the below written adjustments, the following conditions should be fulfilled:
    • The DB8008 should have a static IP Address. If the device is placed behind a router, you will have to make sure that the player port is properly NAT forwarded;
    • On the other side, of the connection, there should be an audio encoder (for example DB9000-TX/DB90-TX) set as RTP Sender.

    Once the above cited conditions are implemented, the following settings should be applied, via the WEB Interface:
    • Go to Settings > IP Stream;
    • RTP Audio Player section - Specify the audio player port and decoder to be used;
    • From Audio, Audio Backup section set the priority of the RTP Audio Player.
    • Configure the RTP sender to stream the audio to DB8008’s RTP port. The port number is 5004 by default.
  • 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 DB8008 to be entered. For further information on how to configure a connection between the silencer and the FTP client refer to the next question.
    DB8008 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 single folder named Audio. The folder should be located in the root of the SD Card. The playlist file have to be named playlist.m3u.
  • How should I configure the connection between DB8008 and the FTP Client?
    1. FTP Server Settings
    It is recommended the default FTP credentials to be replaced with user ones.
    • Using the navigational buttons find the 6.FTP Server 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 & DOWN keys. To move between the parameter's fields use the LEFT / RIGHT keys;
    • Press OK to confirm the selection;
    • Exit the Sub-menu.

    2. IP Router and Port Translation
    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, and the WAN IP Address of the router should be used for connection with the device.
    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 new port values should be used in the port forwarding feature configuration.

    If DB8008 is connected to the same LAN as the computer where the FTP client is installed the LAN IP Address available in menu 4.Network General should be used in order for connection with the DB8008 to be established.

    NOTE: The FTP Server can manage only one connection at a time. The FTP Client as the FTP Server should be in passive mode.

    3. FileZilla Settings
    In some cases, FileZilla's "Quick connect" feature is not able to connect with DB8008. 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".
