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 ON or turn OFF the output of the back speakers,
and adjust the volume, to have the rear/front speakers have the same volume.
