PRODUCT DESCRIPTION
DB9000-TX is an integrated audio converter that converts audio signal into a high quality
compressed audio stream. The signal can be compressed by HE-AAC, MPEG-1 Layer 3 encoder.
DB9000-TX also supports uncompressed PCM stream in order to ensure audio transmission
without quality loss.
Compression is performed in real time, and the output signal is transmitted directly by TCP/
IP-based networks. DB9000-TX can work with both analog and digital audio signal.
With its RS-232 port, DB9000-TX could be transformed into Ethernet to serial Redirector,
allowing to control any other existing equipment over Internet.
DB9000-TX allows you to quickly and painlessly integrate existing audio systems to the
Internet.
Developed with the thought of easiness of use, DB9000-TX can be managed through a standard
Web browser, PC, PDA or other device, making it the best choice for professional and consumer
use.
APPLICATION
• Audio broadcasting over IP-based networks.
• Point-to-Point Audio Transfer (DB9000-RX is required at the opposite site).
• Suitable for professional and consumer use.
• Ethernet to RS-232 Redirector

analog audio inputs of DB9000-TX.
WARNING: Do not exceed maximum input level. This may permanently damage the device.
DIGITAL AUDIO INPUT
Using a cable ending with a standard XLR connectors connect the AES/EBU signal source to
the digital audio input of DB9000-TX.
NOTE: As only one input can be managed by the encoder at certain point of time, please select
the preferred signal source input – either analog or digital one. Selecting the preferred input can be
performed under CONFIGURATION menu (see “Audio Settings” on page 19).
LAN PORT
For normal operation it is necessary the encoder to be connected to a local network or Internet
by cable with RJ-45 connector.

Operation
DB9000-TX is controlled through the built-in web server and a standard web browser can be
used to monitor its status or make some adjustments. To connect to the device you need to know
its IP address and follow the next steps:
• Open a web browser.
• Enter the encoder’s IP address in the browser’s address eld.
• Press <ENTER>.
If you do not know the encoder’s IP address you can hear it through the headphones when you
turn on DB9000-TX. The other option to nd out the IP address is using UPnP discovery in local
networks (see “UPnP and DB9000-TX discovery in Local Networks” on page 27).
The web interface consists of the following pages:
• Status
• Conguration
• Factory Defaults
• Reboot
• Firmware Update
At the top of each page is located the Navigational Menu and underneath, on the left side is the
section with relevant information and adjustments. There is a kind of help section on the right side,
containing brief information about each of the elds on the left.
Hover with your mouse over any of the left side elds to bring out a eld’s description next to
the mouse pointer.

• Network Settings;
• List of Active Connections;
Level of the input signal and the list of active connections are updated dynamically which
makes it possible to remotely monitor encoder’s operation.
Under Network Status are shown MAC address and current IP address, Network mask and
Gateway and the method in which they have been assigned:
• Static Allocation Settings
• Allocated by DHCP server
• Automatically generated

The last option usesAutoIP to generate a unique IP address. This option is activated automatically
when the device is set to use DHCP server (see Network Settings), but such server is not available.
The list of Active Connections provides information for the currently connected clients. Shown
are the IP address and local port of each client. Link duration is visible as well.
In the upper right corner is located LIVE DATA icon. Clicking on the icon will toggle live data
ON and OFF as follows:
- live data is ON
- live data is OFF.

Audio Settings
• Input – select analog or digital input to be used.
• A/D Amplier Gain - Analog input gain in the range from -6 to +18 dB. Default level is 0 dB.
• Channels – select number of the input channels (1 or 2). If only one channel is selected, then
the Left one is used.
• Encoder + Sample Rate – select audio encoder and sample rate.
Available encoding formats are:
- HE-AAC v1 (AAC-LC +SBR)
- HE-AAC v2 (AAC-LC +SBR +PS)
- MPEG1 Layer 3 (MP3)
- PCM (uncompressed)
• Quality – Audio quality varies from 1 (Poor) to 6 (Excellent). Quality determines bitrate of the
encoded stream. For MP3 encoded stream bitrate is independent of other parameters. For HE-
AAC encoded stream bitrate depends on encoder version, number of channels and sample rate
(see table below):
Please note all rates are in kbps.
NOTE: Quality does not apply to PCM stream. For PCM stream bitrate is calculated by the
following equation: (sample rate)*(Number of channels)*16, [bps].
• Stereo mode – selecting stereo mode. Supported modes are Stereo, Joint Stereo or Dual
Channels.
NOTE: This parameter applies only to MP3 stream.
• CRC - selecting whether MP3 stream to contain information on error detection.
Note: This parameter applies only to MP3 stream.
• Emphasis – selecting the emphasis to be applied. Supported values are 50μs, CCITT J.17 and
NO emphasis.
NOTE: This parameter applies only to MP3 stream.

Network Settings
• DHCP – as DHCP Client is used to automatically obtain the Network Settings it can be enabled
or disabled.
• IP Address – a eld where static IP address is to be inserted in case that DHCP client is not used.
Example: 192.168.0.2.
• Netmask – a eld where Static Subnet Mask is to be inserted. This parameter is not used if
DHCP Client is enabled. Example for Netmask is: 255.255.255.0.
• Gateway – a eld where Static Gateway is to be inserted. This parameter is not used if DHCP
Client is enabled. Example for Gateway is: 192.168.0.1.
NOTE: If the encoder’s IP address is changed, it is necessary to enter the new IP address in
your browser.
Stream Server Settings
• Name – this is the encoder’s name displayed as name of the stream.
• Port – a eld where TCP port of the stream server must be inserted. Default value is 5000.
• Pre-buffer – initial amount of data sent to the client. Large value decreases startup delay caused
by buffering on the client side. This also introduces latency in the audio. Latency is bitrate
dependent and can be estimated by the formula: Latency = (PreBuffer x 8) / BitRate, [sec].
Default value is 96k.
• Max connections – maximum number of simultaneous connected clients. This value can be in
the range from 1 to 10. Default value is 2.
WEB Server Settings
• Port – this is the TCP port of the WEB Server. Default value is 80.
• Username – user name for the WEB Server. Default value is user.
• Password – Password for the WEB Server. Default value is pass.
NOTE: You can dene Username only, Password only or both of them. If both Username and
Password are left blank, NO security is used.
RS-232 Settings
• Baudrate - select RS-232 COM port baudrate. Default value is 9600.
• Port - a eld where TCP port of the RS-232 Redirector must be inserted. This is the port to
which your software should connect to communicate with any external device connected to the
RS-232 Com Port. Default value is 9000.
• Password - Pasword for the RS-232 Redirector. These are the rst symbols your software must
send to authenticate itself to the Redirector. If left blank, NO security is used. Default value is
pass.
Applying New Settings
In order new settings to take effect, it is necessary to press the SAVE button. Please keep in
mind that some of the new settings can reset DB9000-TX.
