* Rear audio input ports are re-taskable as Line-in or Microphone-in. External
speakers must be powered externally. Multistreaming can be enabled in the
ADI control panel to allow independent audio streams to be sent to/from the
front and rear jacks. This allows for different audio applications to use
separate audio ports on the system. For example, the front jacks could be
used with a headset for a communications application while the rear jacks
are being used with external speakers and a multimedia application.
