Connect MediaPort 200 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")].
The MediaPort line output sends the program mix signal to the DSP processor. In this
application, select the "AEC Ref Only" radio button for USB Communications audio,
located on the Mix tab in PCS. 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.
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.
Connect from the DSP processor
1. Connect line outputs on the DSP processor to the local sound reinforcement system
[DMP 128 Output 1 ("SP Spkr L") and Output 2 ("SP Spkr R")].
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).
