Installation guide

Connecting Analog Stereo Audio Equipment to the Analog Connector
You can connect analog audio equipment to the stereo analog connector of the XT Codec Unit.
You must enable the echo canceller when working with an external microphone system that
does not contain echo cancellation. See “Configuring the Echo Canceller” on page 52.
Note
The XT Codec Unit’s analog audio input supports a balanced microphone or an unbalanced
line. The analog audio output is unbalanced.
A typical system configuration could be:
•
Connecting the analog audio output by the XT Codec Unit to an amplifier. On the other
end, the amplifier could be connected to speakers. This configuration is useful for large-
size conference rooms.
•
Connecting an audio mixer to the analog audio input. On the other end, the mixer could
be connected to other microphones. This configuration is useful for large-size conference
rooms.
•
Connecting a microphone to the analog audio input.
