10 ASUS Xonar D2
3.5 Connecting TV Tuner Card
1.
If you have a traditional PCI TV tuner card on your PC, you may need to
connect it to the audio card to send the tuner card’s sound to your PC
speakers.
2. Secure the PCI TV tuner card in one PCI slot 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 audio card, as shown in the figure below.
For optimum TV audio quality, Xonar uses ADC recording to digitize the signal
and loops it back to DAC playback. Please select Aux-In as the recording
source in the Xonar Audio 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 Pro-Logic IIx to expand the stereo TV audio to 5.1
or 7.1 channel surround sound. TV audio on your PC will become even better
than on your TV set!
