MediaPort 200 with Exter
nal DSP with AEC
Application Setup Examples
Application 1 — MediaPort 200 with External DSP with AEC
NOTE: Ensure that the MediaPort 200 is set to External DSP with AEC audio mode
in PCS before beginning setup (see
General Settings Tab
on page 59 for more
information about selecting Standalone audio mode).
This is an application for soft codec conferencing, in which the MediaPort 200 operates in
conjunction with a DSP processing device with AEC. The MediaPort Ref output sends far
end USB communications audio to the DSP as an AEC reference. The line output from the
MediaPort 200 sends program audio to the DSP, where it is routed for AEC reference (see
figure 11 on page 19 and the
MediaPort 200 Help
file for more information). The signal
from the DSP output, which includes program and far end audio, is sent to the local sound
reinforcement system.

Connecting MediaPort 200 Inputs and Outputs
1. Connect an HDMI source to the MediaPort HDMI input. Figure 81 above shows an
HDMI video camera as the source.
2. Connect a program audio source to the MediaPort Line input as needed. Figure 81
above shows an iPod as the program audio input.
3. 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.
4. Set the MediaPort 200 to enumerate as a speakerphone device with AEC (see
Configuring Windows for MediaPort 200 on page 27).
