3. Installing the Xonar Hardware

3.1 Preparing Your Computer

Before you proceed with the following installation steps, it’s recommended that you disable your onboard audio device in your BIOS settings, or uninstall any other sound cards on your PC. (For BIOS setting or uninstallation of other sound cards, refer to the user manuals of your motherboard and sound card)
1. Power off your computer and disconnect the power cord.
2. Open the computer’s case.
3. Remove the metal brackets from one unused PCI Express x1 slot for the audio card and its adjacent slot for the MIDI board (You can just remove one if you don’t need to use the MIDI board in the package).

3.2 Installing the Audio Processing Card

1. Face the bracket of the Xonar DX audio card toward the back panel of your computer and insert the audio card gently into an available PCI Express slot. Make sure it’s completely inserted into the PCI Express slot. (Warning! Do not force the audio card into the slot. Make sure that the gold pins of the card's PCI Express connector are aligned with the motherboard’s PCI Express connector before you insert the card into the PCI Express slot. If it
does not t properly, gently remove it and try again.)

ASUS Xonar DX
2. Secure the audio card bracket to the back of your computer with the screw that you removed. Refer to section 3.1.
3. Connect the power cable of your power supply to the power connector on the Xonar DX audio card.
The PCI Express high-quality audio card requires additional power from your computer. If the power cable is not connected properly, the audio card will not work at all.
When removing the power cable from the Xonar DX audio card, make sure to
pull outward the 4-pin header rst, then unplug it from the power connector as

3.3 Connecting 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 audio card to send the tuner card’s sound to your PC speakers.

3. Connect the audio output header from the TV tuner card to the Aux-In header
of the audio card, as shown in the gure 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!
