Front-Panel Audio Header (AUDIO1)
This header allows users to install an auxiliary Front-Oriented Audio port for
easier access. Either the Line-Out port connector on back-panel or Front-
Panel Audio header is available at the same time. If you would like to use this
header on front-panel, please remove all jumpers from the Audio header and
install your special extra audio cable instead. Two mini jumpers must be
setted on pins 5-6 and pins 9-10, when this header is not used.
Extended USB Header (USB3)
The headers are used to connect the cable attached to USB connectors which
are mounted on front-panel or back-panel. But the USB cable is optional at the
time of purchase.
