NOTE: If the channels selected for a virtual reference use Processing or Faders, you should
select the processing or fader channel as the virtual reference source. This provides the
AEC process with the most accurate reference for the signal (after shaping by processing
or fader channels), thereby providing faster convergence and more accurate AEC
performance.
Expansion Bus Reference Sources
Use the Expansion References (1-4) section of the screen to use audio from and expansion bus channel as the
AEC reference source. For each expansion reference, select the Unit and the Output you want to use as an AEC
reference using the drop-down lists.
The following types of sources are available for use as expansion AEC reference sources:
Output channels
Speakers
Virtual references
