ASRock 770DE3L Motherboard
Besides six default USB 2.0
ports on the I/O panel, there are
three USB 2.0 headers on this
motherboard. Each USB 2.0
header can support two USB
2.0 ports.
This header supports an
optional wireless transmitting
and receiving infrared module.
This connector allows you
to receive stereo audio input
from sound sources such as
a CD-ROM, DVD-ROM, TV
tuner card, or MPEG card.
This is an interface for the front
panel audio cable that allows
convenient connection and
control of audio devices.
