6) Bass Center Setting (BCS1, BCS2)
(NOTE: Only available on PCB 1.10 & later versions)
Use these jumpers in conjunction with the C-Media PCI Audio Driver to adjust
output for 6 speaker audio. No audio standard exists for the three pick-up
surfaces on male audio jacks, therefore it may be necessary to switch jumpers
from the default position, type 1, to type 2, in order to reroute signals among the
internal leads to the female Line-In, Line-Out, Mic sockets. Make sure a test is
made using the C-Media Audio Driver software setup available on the Support
CD. These jumpers effectively swap the audio channels for bass and center.
NOTE: the default setting is compatible with Creative 6-Channel audio speaker
system.
