Using the AEC on Network Connections
When the Trio or Conference processor is used in the
ASPEN subsystem, the AEC (acoustic echo canceller)
can be applied to the network connections to suppress
echo caused by acoustical coupling between micro-
phones and loudspeakers. In this example, a local
sound reinforcement system is in place, which further
increases the potential echo.
