General information
The IP Audio encoder and decoder are controlled trough a build in WEB Server and a standard
web browser is used to monitor their status or to make some adjustments. To operate the devices
you need to know their IP Address. In case you are not aware of the IP Addresses and how to open
the WEB interface, please refer to “Appendix A - DB91-TX Quick User Guide” on page 7 and
“Appendix B - DB91-RX Quick User Guide” on page 13.
This conguration allows two types of applications:

POINT TO MULTI-POINT AUDIO TRANSMISSION
IMPORTANT NOTE: One DB91-TX can send audio to maximum ten DB91-RXs. However,
in order for stable connectivity to be guaranteed, the recommended number of clients is 8.
DB91-TX AND DB91-RX SET-UP
Prior to implementing the below written adjustments, the following requirements should be
fullled:
• DB91-TX must have a static IP address;
• If the device is placed behind a router, you will have to make sure that the Stream Server
Port is properly NAT forwarded;
• DB91-RX may have a dynamic IP address;
• DB91-RX should have access to DB91-TX over the network (Internet or LAN).

4. Go to Settings> Encoding;
5. Assign Encoder type;
6. Assign Sample rate;
7. Assign desired Signal Quality.
The combination of these parameters will dene the stream bitrate (see Bitrate Guide table at
the bottom of this screen). The network connection should have enough bandwidth to process
all the streams. As a rough estimate, the bandwidth should be at least twice the stream’s bitrate,
multiplied by the number of simultaneous connections;
8. Press [Save];

192.168.1.20:5000;
3. Choose the preferred Decoder and Pre-buffer. The decoder set in the DB91-RX must
match the encoder specied in DB91-TX;
4. If needed, set new Gain adjustment settings;
5. Press [Save];

STEP 1
1. The encoder has to be connected to the local network or Internet by cable with RJ-45 connector;
2. As only one input at a time can be managed by the encoder, please select the preferred signal source
input - either analog or digital one:
For Analog audio use a cable that ends with two standard RCA jacks to connect the analog signal
source to the analog audio inputs of DB9 -TX;
For Digital audio use a cable that ends with standard RCA jack to connect the S/PDIF signal source to
the digital audio input of DB9 -TX;
3. Connect the device to the power supply.
