Aec Ref And Aux Outs - Extron electronics MediaPort 200 User Manual

AEC Ref and Aux Outs

These two outputs provide special routing capabilities that make it easy to use the
MediaPort 200 with an external DSP matrix processor and/or a hardware video
conferencing device (video codec). The AEC Ref Out carries the only far end USB
Communications audio, while the Aux Out carries only the audio signal from the MediaPort
Mic/Line In.
The illustration below highlights the routing to these two outputs. There are no master
controls for these signal paths. Level is set on the input gain controls and the output
attenuation controls.
Set the input gain for optimal signal levels. Settings for AEC Ref and Aux Out attenuation
controls may remain at 0 dB for unity gain in most cases. Adjust the output controls if the
device connected to these outputs requires a lower signal level, though it is recommended
to adjust the input level of the connected device in this case.
