Getting started
Before you proceed
Read the following notes and precautions before you install the audio card.
• Disable the onboard audio device in the BIOS settings or uninstall any
other sound cards on your computer.
• For BIOS setting or uninstallation of other sound cards, refer to the user
manuals of your motherboard and sound cards.
• Turn off your computer and disconnect all peripherals connected to it.
• Unplug the computer’s power cord from the power outlet.
• To avoid static electricity, use a grounded wrist strap or touch a safely
grounded object such as the metal part or the rear panel of your computer.
Installing the audio card
To install the audio card:
1. Remove the chassis cover of your
computer.
2. Remove the metal bracket of a
PCI slot at the rear panel of your
computer.
3. Carefully insert the audio card into
the PCI slot. Ensure that the audio
card sits properly in place.
4. Secure the audio card with the screw you removed from the PCI slot’s metal
bracket.
7ASUS Xonar Essence ST
5. Connect the power cable of your power supply unit (PSU) to the power
connector of the audio card.
Ensure that the power cable is connected properly. Otherwise, the audio card
will not work.
6. Replace the chassis cover.
7 Plug the computer’s power cord into a power outlet.
8. Turn on your computer.
Connecting to a TV tuner card
If you have a traditional PCI TV tuner card on your computer, you may need to
connect it to the Xonar Essence ST card to send the tuner card’s sound to your PC
speakers.
To connect to a TV tuner card:
1. Secure the PCI TV tuner card into the rear panel with a screw.
2. Connect the audio output header from the TV tuner card to the Aux-In header
of the audio 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 ST 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. This gives you a better TV audio quality on your
computer compared to that on your TV.
8 ASUS Xonar Essence ST
Installing the audio card driver
Ensure that you have installed the VGA card driver before installing the Xonar
Essence ST driver. Otherwise, driver installation error may occur.
To install the audio card driver:
1. After you have installed the Xonar Essence ST card, turn on your computer.
Windows® automatically detects the HDAV card and searches for device
drivers. When prompted for the drivers, click Cancel.
2. Insert the support CD into the optical drive. If Autorun is enabled in your
system, the setup starts automatically. If not, run setup.exe from your
support CD.
3. Follow the onscreen instructions to complete the installation.
4. When the installation is completed, you are prompted to restart your
computer. Select Yes, I want to restart my computer now or No, I will
restart my computer later.
5. Click Finish.
