RTP AUDIO STREAM (ENCODER ONLY)
All encoders (E4100, DuetE-WP, DuetE-WP-H, DuetE-WP-BT, DuetE-2, and E4200) have the ability to transmit up to 8 channels of LPCM audio as an
RTP audio stream. The RTP audio stream may be transmitted as either a unicast or multicast stream. This feature is mainly used to transmit RTP
audio from an encoder to a QSC Core DSP.
1. Access the web interface for the encoder unit that will be transmitting the RTP audio stream and log in with username=admin
password=admin.
2. Click the Configuration tab.
3. Enter an IP address into the STREAM.RTP_ADDRESS filed.
a. To send unicast (recommended), enter the IP address of the QSC Core DSP.
b. To send multicast, enter a unique multicast IP address (example: 225.168.8.100).
4. Enter a port number into to the STREAM.RTP_PORT filed.
a. Must be an even number.
b. Must be 1024 or above.
c. If sending an RTP audio stream from more than 1 encoder, they must all use different port numbers.
5. Go the QSC Designer site design and add a Media Stream Receiver (MSR) object to the design.
6. In QSC Designer go to the File menu and select “Save to Core & Run”
7. Double-click to open the MSR object and enter the following link: http://<IP address of encoder>/audio.sdp
a. Example: http://192.168.8.101/audio.sdp
• The RTP audio stream will be transmitted from the encoder to the QSC Core DSP MSR.
