AEC COMPONENT FUNCTIONS
The AEC component provides four fully independent channels.
On the component, each channel has one input called "far-in", one
output, and one reference called "far-end". The far-end signal will be
removed of the far-in signal, in order to send a proper signal to the
other room.
AEC Coefficient / Reset
On each channel you can independently activate the echo cancellation process by setting the
"AEC Coefficient" parameter on "Perform". You can also let it working without
the process activates, by keeping the AEC coefficient by choosing "Hold". Of
course, you can deactivate it on "Off".
The reset button is used to reset the AEC coefficient.
Volume display and control
The far-end volume and near-end volume vu-meters display respectively the
far-end and near-end volume level.
If you want to modify the volume of a source (near-end inputs), then you have
to use the "Near-End Level" knobs in the AEC component. When the system is
properly adjusted, it is not advised to change the volume by using another
parameter than this one.
