PA Adapt and AEC Reference

When using either the PA Adaptive mode (see page 38) or Acoustic Echo

Cancellation (see page 33), the output that carries this information, i.e. the

reference output, must be defined. Select the PA Adapt and AEC Reference from the

drop-down list. Any one of the 12 outputs, four expansion bus references, or four

virtual references can be selected.

If you select an expansion bus reference, the Define PA Adapt/AEC

Expansion Bus Ref window opens so you can identify which expansion bus output you

want to use as the PA reference. You can also open this window from the toolbar.

If you select a virtual echo cancellation reference point, the Virtual

Reference window will open. This window allows you to select which signals will be

used by the four virtual reference points. Virtual references are used when you

need to reference multiple outputs. The routing matrix portion of this window can

not be edited. You can also open this window from the G-Ware toolbar.

The PA Adapt Reference
and AEC Reference are the
same for each channel. If

you change the PA Adapt Reference
for a channel, you will also make
the same change to that channel’s
AEC Reference.
