Setting up multi-channel audio

2-channel audio
The green line out jack, located on the back panel, is designed to power either headphones or amplified speakers only. Poor audio quality can occur if passive, non-amplified, speakers are connected to this output.


6-channel audio

The back panel audio jacks support up to six speakers and are retaskable using the audio controller interface.

Audio jack retasking is a feature that allows a jack to support more than one function. For example, the pink audio jack can support microphone input when the system configuration is set to stereo mode, 2-channel, and as Center/LFE or Rear Surround, when set to 6-channel mode.

Jack Description
A Line In: Retaskable as Rear Left/Right Out
B Line Out: Front Left/Right Out
C Mic In: Retaskable as Center/LFE (Subwoofer) Out

To set up multi-channel mode using four or six speakers, connect the speakers as follows:

  • With four speakers:
    • Connect the rear speakers to jack A.
    • Connect the front speakers to jack B.
    • Using the audio controller interface, retask jack A to be Rear Left/Right Out.
  • With six speakers:
    • Connect the rear speakers to jack A.
    • Connect the front speakers to jack B.
    • Connect the center/subwoofer speakers to jack C.
    • Using the audio controller interface, retask jack A to be Rear Left/Right Out and retask jack C to be Center/LFE Out.

8-channel audio
8-channel audio is available only on certain Intel® Desktop Boards. After installing the audio driver from the Intel Express Installer CD, multi-channel audio can be enabled:

  • Connect speakers to A, B, C, D, or E as shown in the figure below, up to eight speakers.
  • Two types of S/PDIF connectors are available: coaxial (G) and optical (F). Select the proper connector according to the style of S/PDIF speakers being used.
  • The back panel looks like one of the following images, depending on board model.

Jack Description
A Rear left/right out (multi-channel)
B Line in
C Line out (2-channel) or front left/right out (multi-channel)
D Mic in (re-task for multi-channel)
E Center/Low Frequency Effects (LFE) out (multi-channel)
F Optical S/PDIF (Toslink) line out
