5.Bass Center setting (3-pin BCS1, BCS2)

This jumper allows 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 Line-In, Line-Out, and Mic ports.

Use the audio driver included in the support CD to install the multi- channel audio feature.
