Audio Operations
Suppressing Echo in a Web Conference System
(Echo Canceller)
In a conversation using the speaker and mic of a web conference
system, an echo can occur when the other person’s voice heard
through the speaker is picked up by the mic and sent back to the
other person.
When you use the echo canceller, the echo component is removed
from the voice that is picked up by a mic connected to the V-160HD,
so that only your own voice is sent to the other party.
* This only works on the input audio from the AUDIO IN 1, 2 jacks.
