About the DIN Jack
Your X-Fi I/O Console* features a DIN jack on its rear panel. In order to enjoy
integrated speaker control functions, you can connect this jack to selected
Creative analog speaker systems that have a wired remote control or Audio
Control Pod.
You can, for example, adjust the volume of your speakers, or mute them, using
the Master Volume/Mute dial on your X-Fi I/O Console.
