* 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.
