JP37 and JP38 allow you to change the type of MIC-in port. Normally when we plug a
MIC cable to a 5.1 channel audio device, we connect MIC1 to a center speaker and
connect MIC2 to a subwoofer. However, reverse connection might apply according to
various types of center speakers and subwoofers on the market. By setting those two
jumpers you can have your motherboard in line with your speakers.
