Smart5.1 three jack game/audio port configuration
Fig 1.2
Fig 1.2 above shows VIA's Smart5.1 technology implemented onboard. Smart5.1
requires no additional hardware to implement 6 channel surround sound audio on a
standard VIA Mainboard platform. With Smart5.1 implemented, the left jack
becomes the Front left/right speaker port. The middle jack is for Rear left/right
speakers and the center/subwoofer speaker plugs into the right jack.
The traditional method of implementing 6 channel audio
Fig 1.3
Fig 1.3 shows the traditional method of implementing 6 channel surround sound
audio by using a combination of the left Line-Out jack for Front left/right speaker and
the bottom two jacks on the audio bracket for Rear left/right and center/subwoofer
speakers. The downside to this method is the extra cost associated with the audio
bracket and the extra complexity associated with having the three audio jacks in two
separate places. The audio bracket also places serious restrictions on the design of
entertainment devices, especially small form factor designs because the audio
bracket needs to occupy a PCI bay at the back of a chassis.
