3.3  
Connecting to a TV tuner card  
1. If you have a traditional PCI or PCI Express TV tuner card on your PC, you  
may need to connect it to the Xonar Essence STX card to send the tuner  
card’s sound to your PC speakers.  
2.  
3.  
Secure the PCI/PCI Express TV tuner card and screw it into the back-panel.  
Connect the audio output header from the TV tuner card to the Aux-In header  
of the Xonar Essence STX card.  
For optimum TV audio quality, Xonar HDAV uses ADC recording to digitize the  
signal and loops it back to DAC playback. Select Aux-In as the recording source  
in the Xonar Essence STX 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.
