Application 2 – MediaPort 200 with DSP Processor with AEC
This is an application for soft codec conferencing, where the MediaPort 200 operates in
conjunction with a DSP processing device with AEC (acoustic echo cancellation). The
MediaPort AEC Ref output sends far end USB communications audio to the DSP processor
as an AEC reference. The line output from the MediaPort 200 sends program audio to the
DSP processor, where it's routed for AEC reference and for sound reinforcement. The send
to the sound reinforcement system, which includes program and far end audio, comes from
the DSP processor output.
