7. Bass/Center setting (3-pin BCS1, BCS2) 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 BASS/CENTER (pins 1-2) to CENTER/BASS (pins 2-3) to re-route signals on the internal leads of the Mic port. Use the audio driver included in the support CD to install the multichannel audio feature.
