8 ASUS Xonar DGX
3.2 Connecting to a T� tuner card
1.
If you have a PCIE TV tuner card on your PC, you may need to connect it to
the Xonar DGX card to send the tuner card’s sound to your PC speakers.
2. Secure the PCIE TV tuner card and screw it into the back-panel.
3. Connect the audio output header from the TV tuner card to the Aux-In header
of the Xonar DGX card.
For optimum TV audio quality, Xonar DGX uses ADC recording to digitize the
signal and loops it back to DAC playback. Select Aux-In as the recording source
in the Xonar DGX Center’s recording mixer and enable the monitoring button
to pass this signal to the audio output. Using this setup, you can even turn on
sound effects such as Dolby Headphone to expand the stereo TV audio to 5.1
channel surround sound in any set of headphones. TV audio on your PC will
become even better than on your TV set.
