3.2 Connecting to a TV tuner card
1.
If you have a traditional PCI TV tuner card on your PC, you may need to
connect it to the Xonar D-KARAX card to send the tuner card’s sound to your
PC speakers.
2. Secure the PCI 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 Xonar D-KARAX card.
For optimum TV audio quality, Xonar D-KARAX uses ADC recording to digitize
the signal and loop it back for DAC playback. Select Aux-In as the recording
source in the Xonar D-KARAX 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 Dolby headphone to expand the stereo
TV audio to 7.1 channel surround sound in any set of headphones. TV audio on
your PC will become even better than on your TV set.
6 ASUS Xonar D-KARAX PCIe 7.1 Karaoke Audio Card

3 Analog Out
4 S/PDIF Output
The audio channel refers to the available speaker channels of
available audio sources. It can be used to mix sounds. Select an
audio channel based on the content used. Here are some typical
suggestions:
- MP3, WMA, AAC, CD, VCD, 2D games: 2-channel
- DVD-video with Dolby Digital or DTS 5.1: 6-channel
- DVD-video with Dolby Digital EX or DTS ES: 8-channel
- 3D games: 8-channel
The sample rate determines the number of audio samples per
second that the Digital-to-Analog Converters (DAC) and S/PDIF
digital interface will output.
Please select the sample rate that corresponds to (or exceeds that
of) your playback sources for optimal audio delity. The Xonar
D-KARAX audio card supports sample rates up to 192KHz (44.1K,
48K, 96KHz, 192KHz). Typical values for sample rates are:
- Audio CD, MP3, WMA, Wave les are 44.1 KHz
- DVD-video audio is 48KHz
- DVD-Audio or other HD media may contain 192KHz highdenition audio content
The analog out setting denes your actual speaker setting, such
as front headphones, rear headphones, Dolby headphones, Dolby
rear headphones, 2 speakers, 4 speakers, 5.1 speakers, or 7.1
speakers. Xonar D-KARAX will play the channels and process the
proper 3D surround sound accordingly.
S/PDIF output enables a single digital connection to carry high
quality audio from your PC to digital speakers and AV receivers via
PCM.*
*PCM - Pulse Code Modulation is a typical raw audio data format.

FlexBass is an advanced bass management and enhancement mechanism that
allows you to select each satellite speaker’s type for optimal sound performance.
It comes with an adjustable crossover frequency for the boundary of the bass
signals. FlexBass will lter out the bass signals from small speaker channels and
redirect them to the subwoofer or large speakers.
Standard speakers that cannot produce low frequencies are considered “Small”
while wide-band speakers that can product low frequencies are categorized as
“Large.”

If your speaker type cannot handle low-frequency signals
(bass), select “Small” speaker type. Xonar D-KARAX will
lter out the bass signals and send them to the subwoofer
channel. If the speakers support full-range signals, you can
select the “Large” speaker type.*
*In most cases, low-cost desktop PC 2-channel speakers
are small-type speakers. Refer to speaker’s specications
or consult your speaker vendor to identify correct speaker
type. However, common 2.1 speakers with a subwoofer
should be categorized as large speakers because the
subwoofer can redirect the bass signals inside the two
channels to the subwoofer speaker automatically.

Q1. The audio card driver could not be installed on my PC.
1. Check that the audio card is properly inserted into the PCIe slot on your
motherboard.
2. Run Windows hardware Device Manager and check if a multimedia
audio device is listed. If no device is detected, scan manually for
hardware changes.
3. Reboot Windows.
4. If Windows still fails to detect the audio card, insert the audio card in a
different PCIe slot.
Q2. I cannot find the Xonar D-KARAX Audio Center.
1. Make sure you have installed the driver.
2. Locate the Xonar D-KARAX Audio Center icon in the System Tray on the
bottom right-hand corner of the screen. Double-click the icon to open the

3. If the icon is not displayed on the System Tray, go to Windows Control
Panel and double click the “Xonar D-KARAX Audio Center” icon to make
it visible in the system tray again.
4. After driver installation is complete, it’s recommended that you reboot
your computer to complete the setup. If the icon is still not available,
reinstall the device driver.
Q3. I cannot hear any sound from my analog speakers.
1. Check that you have connected the speakers properly and have
powered on your speakers.
2. Check that the device master volume or the software player is not set to
mute on the Xonar D-KARAX Audio Center.
3. Go to the sound and audio device settings found in Windows Control

Q4. I cannot hear any sound from the S/PDIF output.
1. Check that you have enabled S/PDIF output in the Audio Center GUI.
2. Check that you connected the correct S/PDIF output port on the card to
the decoder’s (AV receiver) S/PDIF input port.
3. You may need to select the correct input and mode of your decoder or
AV receiver.
4. If you are using 96KHz or 192KHz PCM output, make sure your decoder
can support 96KHz or 192KHz decoding. Change the PCM output to
44.1K or 48KHz to check if your output device supports a lower value.
Q5. I cannot hear audio input (Mic, Line-in, AUX, etc.) from my speakers.
1. On the mixer recording page in the Audio Center, select the correct
input as the recording source.
2. Remember to turn on the digital monitoring button for that recording
source.
Q6. I cannot hear the TV tuner audio from my speakers.
1. If you are using a TV tuner card with an analog audio output, connect
the analog audio output to the Aux-In header on the audio card.
2. Select Aux-In as the recording source and on the digital monitoring
button on the recording mixer page.
3. If you are using a TV tuner card with a digital audio output, check
that the sound is not set to mute and whether other applications can
playback sound. If you still have a problem hearing audio, refer to the
TV tuner card’s user guide.

software to convert the sound les to 48KHz. Please note that the frequency
meter on the Xonar D-KARAX Audio Center will not take effect when the
playback source is at a 96KHz or 192KHz sample rate to prevent any
processing distortion.
