UA-1D

The UA-1D is the simplest way to add S/PDIF connections to your computer. S/PDIF (Sony/Philips Digital Interface) is a standard audio transfer file format. A S/PDIF connection is used to transfer audio from one file to another without the conversion to and from an analog format, which could degrade the signal quality. And now it's available as an add-on to your USB-equipped laptop or desktop computer. The UA-1D is equipped with both optical and coaxial digital connections, providing you with the ability to connect any device that conforms to the S/PDIF standard, including component CD recorders, minidisk players/recorders, digital home receivers, DAT, etc. The UA-1D is also packaged with WinDVD so you can send Dolby Digital or DTS encoded audio to your home theater system.
