DB9000-TX

Professional IP Audio Encoder

High precision and Optimal Effectiveness

The DB9000-TX is a multi protocol Audio over IP encoder, operating with either analog or digital audio. The signal compression is performed in real time, using the HE-AAC or MPEG-1 Layer 3 encoder and transmitted via TCP/ IP-based network to one or multiple decoders. In order for audio transmission without quality loss to be ensured, DB9000-TX also supports an uncompressed PCM stream.

The DB9000-TX can act simultaneously as an Icecast compatible Server, Icecast source client, or a Real Time Protocol (RTP) sender. Via the RS-232 port, the DB9000-TX could be transformed from Ethernet to a serial Redirector, allowing control of any other existing equipment over the Internet. The DB9000-TX allows quick integration of the existing audio systems to the Internet. Additionally, the unit can be managed through a standard Web browser and UPnP for easy connection via local area networks. Android and iOS devices are also supported.

DB9000-TX is a multi protocol Audio over IP encoder, specially designed to serve DEVA's most demanding clients.

Encoding the analog audio sources into high quality configurable format happens in real time by HE-AAC Versions 1 and 2 or MPEG-1 Layer 3. DB9000-TX supports PCM uncompressed audio, guarantees audio transmission without quality loss.

Operating with either analog or digital audio signal, the device compresses the output signal, directly transmitted over IP-based networks to one or more (up to 10) decoders such as DB9000-RX, DB90-RX or other compatible IP audio players.

Once an audio source is selected, the encoded in real time audio is immediately sent to the network. DB9000-TX can act simultaneously as an Icecast compatible Server, Icecast source client or Real Time Protocol (RTP) sender. The audio stream can be spread over an IP-based network to one or more (up to 10) DB90-RX or other compatible IP audio decoders. Using the RS-232 port, DB9000-TX could be easily transformed from an Ethernet to a serial Redirector, enabling management of third party RS-232 managed equipment.

Highly valued by the professional broadcasters and situated on thousands of locations all over the world, DB90-TX allows management by any kind of web browser from your PC, PDA or any kind of mobile device. That is what makes it the best choice for professional and consumer use.

    For further information on the variants of usage when DB9000-TX/DB90-TX cannot be set with static IP, refer to question:
    "How DB9000-TX/DB90-TX can be used as an Icecast Source Client, feeding with audio DB9000-RX/DB90-RX, working as an Icecast Source Server, or an Icecast Distribution Server?"
    "How DB9000-TX/DB90-TX can be used as an RTP Sender, feeding with audio DB9000-RX/DB90-RX, working as an RTP receiver?"
  • 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.
  • Can the DB90-TX/DB9000-TX be used as an audio source for Shoutcast system?
    The DB90-TX/DB9000-TX can be used as an Icecast Source client, but not as Shoutcast Source. Shoutctast/Icecast in the product specifications refers to the built-in Icecast/Shoutcast compatible stream server, i.e. clients as Winamp, for example, can connect to DB90-TX/DB9000-TX and play the audio.
