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 function, the echo component is
removed from the voice that is picked up by a mic connected to the
VR-1HD, so that only your own voice is sent to the other party.

other party to make echo canceller settings.

About the AUX Bus

A "bus" is a destination to which input audio is mixed and sent.
The VR-1HD has two buses: the "main bus" and the "AUX bus. "
With the exception of the MAIN connector, you can assign a
desired bus to each output connector.
7 Main bus
This mixes and outputs all input audio. This is the same audio as
the main output.
7 AUX bus
This mixes and outputs only the input audio that is sent to the
AUX bus. This allows you to output audio that is different than the
main output.
For example, in a live event, you might output a mix of all audio
inputs (the main bus), while separately outputting a mix of only
specific audio inputs (the AUX bus) for recording or streaming.
