Motherboard Layout
The following diagrams show the relative positions of the jumpers, connectors, major
components and memory banks on the motherboard.
# The LAN Connector is optional.
# The ALC650/ALC655 embeds an internal analog switch (by driver software)
to share LINE input with Surround output, and share MIC input with CENTER/
LFE output.
NOTE
1) Be sure to check the cable orientation in order to match the colored strip to the pin
1 end of the connector.
2) Be sure to connect PW1 and PWR1 to power supply correctly, otherwise, the mother
-board can’t work normally.
3) When you start up the system, please wait for 5 seconds after you power on AC.
4) It is not recommended to add a metal spacer plate on the back of the Socket775.
Otherwise, some components will be short and damaged.

Audio Configuration
ALC650/655 support 6 channel output,after installing the audio driver,
you can select 4/6 channel surround audio output in software utility and then
connect surround speakers to appropriate audio ports.
There are two ways to obtain 4/6 channel surround audio output:
1. 4/6 surround audio output of back panel only. All surround speaker
connect to audio connector.
2. S-Bracket (optional cable). You have installed S-Bracket into the
computer, and then connect two front speakers to back panel’s
“Line-out” port, and the rest of speakers to S-Bracket. Detail connection
is refer to Page 25.
Speaker Configuration
Method 1: 4/6 Surround audio output of back panel only.
After installing the audio drivers, you can attach the speakers for 2-/4-/6-
channel audio output. Always connect the speakers to the LINE OUT
connectors. Different connector configurations for 2-/4-/6-channel
operations are listed below:
2-Channel 4-Channel 6-Channel
In 2-channel configuration,
Line Out, Line In and MIC
functions all exist.
When set to 4-channel
configuration, Line In
is replaced by Rear
Speaker Out. Line in
function does not exist.
When set to 6-channel
configuration, Line In
is replaced by Rear
Speaker Out. Mic is
replaced by Center/
Subwoofer Speaker Out.
Line in and Mic do not
exist function.

In utility, double click “AC97 Audio configuration” icon from the
window tray on the right bottom.
Then the “AC97 Audio Configuration” will appear. Click on the Speaker
Configuration tab to select the audio mode.
