9. Bass/Center setting (3-pin BCS1, BCS2) (on audio models only)
These jumpers allow you to select the speaker output for a 6-channel
audio system. No audio standard exists for the three pick-up surfaces
on male audio ports, so it is necessary to switch the jumpers from the
default position CENTER/BASS (pins 2-3) to BASS/CENTER (pins
1-2) to re-route signals on the internal leads of the Mic port.
Use the audio driver included in the support CD to install the multi-
channel audio feature. See section “5.3 Software information.”
