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.)

6

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

the following pictures show. Do not forcefully remove the header from the power

connector; doing so may pull up the power connector from the audio card and

cause damage!

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.

2. Secure the PCI/PCI Express 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 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!
