Installation

1. Connect the front pair speakers to the Line-out jack of the audio adapter, and

then connect rear pair speakers to Line-in/Rear jack of the audio adapter. The

original Line-in can be moved to Aux-in.

2. Install the audio driver and Audio Rack application software(see chapter 4).
3. There is a multi speakers option in the volume control of the mixer, and when

you enable this option, it means the rear speakers are connected to Line-in/Rear

jack. When Line-in/Rear jack is connected to other external Line-in sources,

please DO NOT enable this option in order to avoid hardware conflicts. Regarding

rear speaker option, you can turn

or turn

OFF

the output of the back speakers,

and adjust the volume, to have the rear/front speakers have the same volume.

Note

: You can test your multi-channel system by clicking the Multi-Channel Audio

Demo at C:\WINDOWS\Start Menu\Programs\PCI Audio Application\Multi-

Channel Audio Demo(as shown in figure below).
