3.2 Connecting to a TV tuner card
1. If you have a traditional PCI TV tuner card on your PC, you may need to
connect it to the Xonar D-KARAX card to send the tuner card’s sound to your
PC speakers.
2. Secure the PCI 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 D-KARAX card.
For optimum TV audio quality, Xonar D-KARAX uses ADC recording to digitize
the signal and loop it back for DAC playback. Select Aux-In as the recording
source in the Xonar D-KARAX 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 7.1 channel surround sound in any set of headphones. TV audio on
your PC will become even better than on your TV set.
