3.Installing the Xonar Hardware

3.1Preparing 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 the computer, the monitor, and all other peripheral devices connected to your computer.

2.Unplug the computer power cord from your computer and power outlet.

3.Touch the metal back or side panel of the computer to avoid static electricity.

4.Remove the chassis cover.

5.Remove the metal bracket from an

available PCIE slot for the Xonar Phoebus audio card.

3.2Installing the Audio Processing Card

1.Face the bracket of the Xonar Phoebus 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 fit properly, gently remove it and try again.)

ASUS Xonar Phoebus

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 Phoebus 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.

ASUS Xonar Phoebus

3.3Connecting TV tuner card

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.

1.Secure the PCI/PCI Express TV tuner card and screw it into the back-panel.

2.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!

ASUS Xonar Phoebus

4.Installing Software

4.1Installing the Audio Card Driver

1.After you have installed your audio card, turn on your computer. Windows automatically detects your audio card and searches for device drivers. When prompted for the audio drivers, click the Cancel.

2.Insert the Support CD into the optical drive. If Windows® AutoPlay mode is enabled in your system, the setup starts automatically. If not, double-click the setup.exe from your Support CD.

3.Follow the onscreen instructions to finish the installation.

The version and content of the support CD are subject to change without notice.

4.2Uninstalling or Reinstalling Software

4.2.1Uninstalling Software

1.Click Start -> Settings -> Control Panel.

2.Double-click the Add/Remove Programs icon.

3.Click the Change or Remove Programs button.

4.Select each program you would like to remove, and then click the Add/ Remove (or Change/Remove) button.

5.In the InstallShield Wizard dialog box, select the Remove option.

6.Restart your computer when prompted.

ASUS Xonar Phoebus

4.2.2Reinstalling Software
