The GefenTV High Resolution USB to Analog and Digital Audio Decoder is ideal for anyone who wants to listen to streaming digital media coming from a computer to their analog or digital sound system using left/right speakers. The decoder supports digital audio up to 24 bits and 192kHz sampling rate coming from the USB port of a Windows PC or MAC computer, and converts it to optical digital (TOSLINK®) and analog left/right audio. The outputs of the decoder can be connected to A/V Receivers, analog pre-amplifiers, or headphones. It is compact, easy to install, high performance, and versatile.

 If you are using a Windows PC, install the Gefen USB driver. If using a MAC, no installation is necessary. Connect the included USB cable from the USB source to the decoder. Connect a TOSLINK or L/R RCA cable from the decoder to the A/V Receiver or analog amplifier. Headphones can also be connected to the decoder. Power is supplied by the source over the USB cable. 
Note: The source must be configured to output high resolution 2 channel LPCM audio through USB. This product does not support Dolby Digital® or DTS® encoded audio.
