To use the Bravo as a USB to S/PDIF converter you simply connect the USB cable from any available USB port on your computer to the USB input of the Bravo. Then connect either the Digital Coax or Toslink optical output to your external DAC or AV Receiver. Sit back and enjoy.
The Bravo also serves as a 24 Bit / 96 kHz digital processor. The Bravo is effective at dramatically reducing digital noise and distortion. Connect any Digital Coax or Toslink Optical input and then output to either Digital Coax or Toslink Optical. The resulting output signal is significantly cleaner than the input.
