MediaPort 200 with Exter
nal DSP with AEC
Connecting the MediaPort 200 Inputs and Outputs
1. Connect an HDMI source to the MediaPort input. In figure 86 on the previous page, 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 audio source to the MediaPort Line input as needed.
Figure 86
on
the previous page shows an iPod as the program audio input.
4. Connect a USB cable between the MediaPort rear panel USB type B connector and the
PC or Mac computer. Make sure that the drivers are configured properly.
Connecting the MediaPort 200 to the DSP
1. Connect the Line output of the MediaPort 200 to line inputs on the DSP (DMP 128 input
9 and input 10, see
figure 86 on the previous page).
2. Connect the Ref output of the MediaPort 200 to a line input on the DSP (DMP 128 input
11).
3.
Uncheck the
Mix USB Communications
checkbox in the
Near End
panel of the
Mix
tab in PCS.
The Ref output sends the USB communications signal (far end audio) from the
MediaPort to the DSP. The DSP user this signal as an AEC reference on each
microphone input, and also routes it to the sound reinforcement system.
4. On the MediaPort 200 PCS software
General Settings
page,
Audio Mode
panel,
select
External DSP with AEC
.
5. Connect a line output on the DSP to the Mic/Line Input of the MediaPort 200 (DMP 128
output 3).
This line output sends the MediaPort 200 a mix of the microphones connected to the
DSP.
Connecting the Video Codec to the DSP
1. Connect a line output of the DSP (DMP 128 output 4) to the input of the video codec.
This can be the microphone input of the video codec, although preferably it would
be able to receive a line level signal. See the user guide of the video codec for the
appropriate input and settings.
This line output also sends a mic mix connected to the DSP to the video codec.
2. Connect the mono line output of the video codec to a line input of the DSP (DMP 128
input 12, “Video Codec”).
Connecting Inputs to the DSP
Connect up to eight microphones to DMP 128 inputs 1 through 8. After selecting the
microphone types, Extron Building Blocks can be used to configure the mic channels for
gain and processor settings (see the
DMP 128 User Guide , available from the DMP 128
web page , or the DSP Configurator Help file for information on Building Blocks).
Connecting the DSP to Sound Reinforcement System
Connect line outputs on the DSP to the local sound reinforcement system (DMP 128
outputs 1 and 2).
This line output contains a mix of the local program material routed from the MediaPort
Line output plus the USB communications audio that had been routed to the DSP from the
MediaPort Ref output.
