* 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.
