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

.
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.

Multiple decoders can be grouped together to create a video wall. Setup involves assigning each decoder to its position in the video
wall. The decoders create a video wall by scaling the video content to a size that matches the full video wall.
When video walls are square (same number of rows and columns), the content will be scaled appropriately because the aspect ratio
is maintained. When video walls have a different number of rows and columns, the content will be stretched by the video wall
processor. Standard 16:9 content will appear wider or taller than normal. To maintain the proper aspect ratio on video walls that
have a different number of rows and columns, content should be custom created. The decoders also have the capability to rotate the
video output clockwise.
Note
: Check the
Zoom
settings on each display to get the best fit. Look for options like
Screen Fit
(Samsung),
Full Pixel
(Sony),
Dot-
by-Dot
(Sharp), or J
ust Scan
(LG). The effect of these preferences is to turn off HDMI Overscan.
The following step-by-step instructions describe how to configure a 2x2 video wall. As you change these parameters, the diagram
representing these settings automatically adjusts to provide you with a visual guide.
1. Access the web interface for each decoder unit that will be part of the video wall and log in with
