VCR AUD IN
connector (see

).
VCR Audio Mix
Select the appropriate mixing
mode. Mixing modes
determine how the audio from a VCR connected to the
HD3000 is mixed and sent to the remote party or
recorded to a VCR cassette.
For a guide to selecting the appropriate mixing mode for
your purposes, see
“Setting Mixing Modes” on page 70

Acoustic Echo
Cancellation
When the microphone picks up audio from your
speakers, an echo is created. Acoustic Echo
Cancellation (AEC) suppresses this effect. By default,
AEC is turned on.
You should disable AEC only if audio input comes
through a Line Level connection from a playback device
that does not capture sound from the conference room.
