DB9000-RX

Professional IP Audio Decoder with Stereo & RDS Encoder Module

Premium Rebroadcast, Total Control Exercising

The DB9000-RX is a reliable IP to Audio decoder, designed to support HE-AAC and MPEG-1 Layer 3 compressed audio streams and PCM uncompressed stream for audio transmission without quality loss.

As required in equipment of this class, the DB9000-RX comes with several IP audio sources and a built-in MP3/AAC Backup Audio Player. If the audio signal from the main source disappears, the device will switch to the first available backup source, as per the user-defined source priority; when the Main source returns, the unit reverts back to it.

With the optional Stereo and RDS Encoders added, the DB9000-RX becomes a complete tool for audio rebroadcasting. The stereo encoder processor enables a fully digital composite MPX signal with high stereo to be generated. Thanks to the RS-232 port, the DB9000-RX can be transformed from Ethernet to a RS-232 redirector, allowing the control of any other existing equipment over the Internet. The DB9000-RX can be also managed via any kind of Web browser.

DB9000-RX is a professional and highly reliable IP to Audio decoder. It comes with an HTML5 based web server for device management and Ethernet to a RS-232 Redirector, enabling quick integration of the existing audio systems to the Internet. The device is available with an optional fully digital, DSP-based Stereo & RDS Encoder Module.

Supporting the compulsory for this high class equipment HE-AAC versions 1 and 2, MPEG-1 Layer 3 compressed audio streams and PCM uncompressed stream, the DB9000-RX can be used for a scope of professional audio applications: Broadcast, Internet Radio, Studio to Transmitter Link and VoIP.

The powerful DSP processor and either digital or analog output signals allow for the decoding process to be accomplished in real time which makes the device compatible with any online radio system, including Icecast and Shoutcast. Another impressive addition to DB9000-RX features is the low latency Real Time Protocol (RTP) connection support.

Along with its main IP audio source DB9000-RX comes with several IP audio sources and a built-in MP3/AAC Backup Audio Player for higher stability. The device has a built-in FTP server and 2GB SD card where the audio content for the MP3 Player is recorded. The backup audio files can be easily managed anytime remotely via any FTP client.

If the audio signal of the main source disappear, the device will switch to the first available IP audio backup source. If none of the audio backups are available then the MP3 Player starts. While when the main audio signal is recovered, DB9000-RX will automatically switch back to it. Depending on your needs, the sequence of the backup audio sources can be easily changed.

DB9000-RX TYPICAL APPLICATIONS:

1. Audio Transmission over IP-based networks (DB9000-TX or DB90-TX is required at the opposite site)

2. Audio Transmission over IP-based Point-to-Point Wireless Link

3. MultiPoint Audio Transmission over IP-based networks

4. Low delay Real time Audio Transmission

In line with the latest technology, one or more DB9000-RX devices in combination with an encoder, (such as DB9000-TX and DB90-TX, for an instance) offer a full sound solution for long distance wireless needs.

Frequently Asked Questions
  • I have forgotten my password for the WEB Interface. What should I do?
    If due to any reason you have forgotten your WEB Interface password, in order for a new password to be assigned to the device, the unit should be returned to its factory defaults.
    The procedure is performed via the reset button placed on the rear panel of the device. To ensure that the procedure has been properly completed, please follow the instructions below:
    • Unplug the device from the power supply;
    • Press and hold the reset button;
    • While pressing the button, connect the device to the power supply again;
    • Wait for a few seconds, until the Power LED starts blinking;
    • Release the reset button;
    • The device should be returned to its factory defaults.
  • Can the DB9000-RX be used as a multicast receiver?
    The DB9000-RX IP Audio Decoder currently does not support Multicast reception.
  • How can the decoder be used as an IP Audio client?
    One of the following conditions should be fulfilled, prior any adjustments are applied:
    • A DB9000-TX/DB90-TX or other encoder 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 Audio;
    • 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 Source priority Section set the priority of the IP Audio Client.
  • How can the decoder be used as an Icecast Source Server?
    Prior to implementing the below written adjustments, the following conditions should be fulfilled:
    • The DB9000-RX/DB90-RX 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 a DB9000-TX/DB90-TX set as Icecast Source Client or other Icecast Source Client.

    Once the above cited conditions are implemented, the following settings should be applied, via the WEB Interface
    • Go to Configuration > IP Audio;
    • Icecast Audio Player Section - Specify the audio player port, username, password and decoder to be used;
    • From the Source Priority section set the priority of the Icecast Audio Player.
  • How can the decoder be used as an RTP Receiver?
    Prior to implementing the below written adjustments, the following conditions should be fulfilled:
    • The DB9000-RX/DB90-RX 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 a DB9000-TX/DB90-TX or other encoder set as an RTP Sender.

    Once the above cited conditions are implemented, the following settings should be applied, via the WEB Interface:
    • Go to Configuration > IP Audio;
    • RTP Audio Player section - Specify the audio player port and decoder to be used;
    • From the Source Priority section set the priority of the RTP Audio Player.
  • What should be the buffer level? How can I apply the needed settings?
    The Buffer is used to supply an audio at the output when disconnection or a problem with the connection is present. The higher the buffer level is the longer the protection time will be. Though, the audio delay will be increased. The level at which the buffer will be set depends on your preferences and expected results as it comes to the quality of the connection. If a connection loss is not expected, the buffer level could be decreased. If the connection is unstable (such as 3G Network), we recommend a higher buffer level to be set.
    The buffer level is set in bytes, thus, the audio delay depends on the bit-rate of the audio stream. For example - audio with higher bit-rate will have a lower delay compared to audio with the lowest bit-rate at the same level of the buffer.
    The buffer level is the received amount of audio data at which the RX will start playing the audio. In the DB90/9000-TX settings should be set the pre-buffering level, which is the initial amount of data that is sent to the RX in order for the buffer to be filled rapidly i.e. the connection to be built quickly. We recommend the same values to both units to be set.
    All needed settings are applied via the WEB Interface.
    • For DB90/9000-RX go to Configuration > IP Audio > IP Audio Client subsection and set the pre-buffer level;
    • For DB90/9000-TX go to Configuration > IP Audio > Stream Settings subsection and select the pre-buffer level from the drop-down menu.
