system that does not contain echo cancellation.
To configure the echo cancellation settings, see “Configuring the Echo
Canceller” on page 52.

echo cancellation.
Audio selection Choose one of these settings:
•
Analog associated with DVI - Select this option when a PC is
connected to the XT Codec Unit’s DVI-I Input port and you want to
hear the PC’s audio.
•
Analog always - The audio coming from analog connection is
always selected.
Line In a stand-alone microphone, power and audio can be supplied over
the same wires; power is drawn from an external source called
phantom power. A built-in microphone, such as a in a computer, does
not need phantom power since it gets power from the device itself.
When configuring these settings, verify the audio equipment
connection method: a balanced line reduces external noise
interference and allows to use very long cables.
Choose one of these settings:
•
Line - Select this option for an analog audio input without
phantom power. Then set the Mode field to Stereo or Mono
input.
•
Microphone - Select this option if the analog audio is coming from
an analog balanced microphone with phantom power turned on.
Mode You can configure this field if you selected the Line setting. Choose
one of these options:
•
Stereo - The input is an L/R stereo unbalanced line without
phantom power.
•
Mono - The input is a mono balanced line without phantom
power.
Step 6
Select Save.
Step 7
(Optional) If Analog is associated with DVI, verify the DVI input is enabled in Administrator
Settings > I/O Connections > Cameras > DVI. Press
to start data sharing.
