Connect to the MediaPort 200
1. Connect an HDMI source to the MediaPort input. For this example, an HDMI video
camera is used.
2. Connect the HDMI loop out on MediaPort to the camera input or content input on the
hardware video codec.
3.
Connect a program source to the MediaPort Line Input (as needed).
4. Connect a USB cable to the MediaPort rear panel USB connector and your PC or Mac
computer. Make sure that the drivers are configured properly.
5. Set the MediaPort 200 to enumerate as a Speakerphone device with AEC.
Connect MediaPort to the DSP matrix processor
1. Connect the line output of the MediaPort 200 to line inputs on the DSP processor [DMP
128 Input 9 ("MP Program L") and Input 10 ("MP Program R")].
2. Connect the AEC Ref output of the MediaPort 200 to a line input on the DSP processor
[DMP 128 Input 11 ("MP Far End")].
The AEC Ref output sends the USB Communications signal (far end audio) from the
MediaPort to the DSP processor. This signal is used in the DSP processor as an AEC
reference on each microphone input, and also routed to the sound reinforcement
system from the DSP processor.
3. Connect a line output on the DSP processor to the mic input of the MediaPort 200
[DMP 128 Output 3 ("To MP Mic In")].
This line output sends a mix of the microphones connected to the DSP processor to the
MediaPort.
Connect the video codec to the DSP processor:
1. Connect a line output on the DSP processor (DMP 128 output 4) to the input of the
video codec. This may be the microphone input of the video codec, although preferably
it should be able to receive a line level signal. Check the user guide of the video codec
to find the appropriate input and settings. This line output also sends a mix of the
microphones connected to the DSP processor to the video codec.
2. Connect the mono line output of the video codec to line inputs on the DSP processor
[DMP 128 Input 12 ("Video Codec")].
Connect from the DSP processor:
1. Connect line outputs on the DSP processor to the local sound reinforcement system.
(DMP 128 outputs 1 & 2.)
This line output will contain a mix of the local program material routed from the
MediaPort Line Out plus the USB Communications audio that had been routed to the
DSP processor from the MediaPort AEC Ref out.
Connect to the DSP processor:
1. Connect up to eight microphones to DMP 128 Inputs 1 – 8. Once the microphone
types are selected, Extron Building Blocks can be used to configure the mic channels
for gain and processor settings (see the DMP 128 User Guide or DSP Configurator
Help File for information about Building Blocks).
