Connecting to a TV tuner card  
1. If you have a traditional PCI or PCI TV tuner card on your PC, you may need  
to connect it to the Xonar DS card to send the tuner card’s sound to your PC  
speakers.  
2.  
3.  
Secure the PCI/PCI TV tuner card and screw it into the back-panel.  
Connect the audio output header from the TV tuner card to the Aux-In header  
of the Xonar DS card.  
For optimum TV audio quality, Xonar DS uses ADC recording to digitize the  
signal and loops it back to DAC playback. Select Aux-In as the recording source  
in the Xonar DS 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.

Sample Rate  
6.2.1  
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.  
The Xonar DS card can support sample rates up to 192KHz (44.1K, 48K, 96K,  
192KHz). Usually audio CDs and MP3 files are 44.1KHz; DVD-Video uses 48KHz;  
DVD-Audio or other HD media may contain 96KHz or 192KHz high-definition  
audio content. Please select the corresponding sample rate for your playback  
sources to get the best audio fidelity. Even if your setting differs from the audio  
source’s sample rate, the Xonar DS engine will do super high fidelity sample-rate-  
conversion with a double floating-point filter, which can reduce total harmonic  
distortion (THD+N) by -140dB.

option  
Select the speaker type that you connected. If your speaker  
type cannot perform low-frequency signals (bass), select  
“Small” speaker type and Xonar DS will filter out the bass  
signals and send them to the subwoofer channel. If those  
speakers are full-range, you can select the “Large” speaker  
type.  
Note: Usually, low-cost PC’s 2-channel speakers are  
small-type speakers. Refer to the speaker’s specification.  
If you have any questions, consult your speaker vendor.  
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.

DS3D GX and DSP Modes  
Xonar DS is introducing an innovative technology –DirectSound 3D Game  
Extensions v2.5 (DS3D GX 2.5)- to restore DirectSound 3D Hardware acceleration  
mode and its subsidiary EAX effects on Windows Vista for 3D games. Unlike some  
proprietary API like OpenAL, DS3D GX doesn’t require games to support OpenAL  
API. All existing games compatible with Microsoft DirectX and DirectSound 2D/3D  
will be supported with DS3D GX technology. Before you start EAX and DS3D HW  
games, enable DS3D GX on the Xonar Audio Center, and disable the function after  
the games.  
In addition, Xonar DS also offers a Hi-Fi mode for hi-fidelity playback without any  
effect processing to keep the original audio fidelity. Every time you turn on Hi-Fi  
mode, Xonar DS will clear all sound effects. It’s also recommended to use Hi-Fi  
mode for audio quality tests (using RMAA software or another machine-based  
measurement). Use the DSP mode button as the quick setup if you don’t wish to  
know the details of the effect setup.  
No sound effects will be applied to high-definition 96KHz/192KHz content.

[FAQ]  
Q1: Does the Xonar DS support Windows Vista?  
Answer:  
Yes, the Xonar DS driver package does support Windows Vista 32/64 bit and most  
key features are available. In addition, Xonar DS supports unique DS3D GX on  
Windows Vista, which can recover DirectSound 3D hardware and EAX gaming  
sound effects on Vista for a lot of existing DirectX games.  
Q2: Why does the Xonar DS support DTS technology?  
Answer:  
DTS is the well-known brand and technology recognized by the CE industry and  
available on a wide range of audio equipment. Moreover, DTS Digital Surround 5.1  
audio could deliver more high-quality sound even than Dolby Digital does. Xonar  
includes these features to make your PC a powerful media and entertainment  
center.  
Q3: Why is Xonar DS the best audio card for HTPC and multi-channel  
speakers?  
Answer:  
The Xonar DS supports DTS Interactive, which allow a single digital connection to  
your AV receiver to carry DTS Digtial Surround audio. In addition, Xonar DS also  
provides DTS Neo:PC to upmix TV and other music to multi-channel surround  
sound in Home Theater environments. Xonar DS also has High Fidelity SNR  
at 192K/24bit, which is the only high quality consumer audio card in the world.  
Therefore, it’s also the best card to deliver the high quality audio through an analog  
connection to your home theater system or high-end multi-channel speakers.  
Q4: Does the Xonar DS support EAX on Vista?  
Answer:  
Yes, Xonar DS can support EAX2.0 not only on Windows XP but also on Vista  
through innovative DirectSound3D Game EXtensions v2.5 (DS3D GX 2.5)  
technology.  
Q5: Why do I need DTS for PC games?  
Answer:  
DTS Interactive and Neo:PC are available on the latest game consoles, like  
XBOX360, and PS3. DTS can provide the best gaming sound experience and  
compatibility with home theater or TV systems.  
ASUS Xonar DS  
45  
 
Q6: What is the most important benefit of the Xonar DS for musicians?  
Answer:  
1.  
2.  
3.  
Ultimate Fidelity: Xonar DS has the highest quality of audio in/out for the  
cleanest sound production.  
Duplex HD: Supports audio sampling rates up to 24bit/192KHz for outputs  
and 24bit/96KHz for inputs.  
ASIO 2.0: Xonar DS includes an ASIO 2.0 driver for low-latency, low-  
distortion music creation application.  
Q7: Will PCM sound output through S/PDIF be just 2 channels even with  
different analog output channels?  
Answer:  
The S/PDIF protocol specification (IEC-60958) can only carry 2-channel PCM  
data or non-PCM AC3/DTS data. So, when a user selects PCM output for S/PDIF,  
the Xonar sound card will always deliver 2 channel PCM data through the S/PDIF  
output port. For attaining 5.1 channel surround sounds, you can select DTS  
Interactive encoding output from the S/PDIF out menu, which will allow the Xonar  
DS to deliver upto 7.1 surround sound for games, DVD movies, and even stereo  
music.  
Q8: Why can I hear and record sound from other recording devices when  
Wave/Digital is selected in Record on Vista?  
Answer:  
Different from Windows XP, Vista has a multiple devices/streams concept in audio  
structure, in which the concept can be categorized into Digital Input and Analog  
Input. In other words, multiple recording devices can be used and working at the  
same time. In this case, Wave In or SPDIF-In, considered as a Digital Input, is  
an independent recording device from Analog Devices such as Mic In, Line In,  
or Aux In. Therefore, if you have analog inputs other than Wave In and set to be  
monitored, you are able to hear and even record sound from those analog devices  
even Wave In / SPDIF-In is selected as the default recording device.  
If you don’t want to hear the analog input sounds at that situation, simply turn off  
“monitoring” function on other analog input devices.  
ASUS Xonar DS  
46  
Q9: Why do I found no sound effects when playing 96K or 192KHz sound  
sources.  
Answer:  
Currently Xonar DS effects including DTS support common 44.1K, 48KHz sound  
sources processing and will assure high-definition audio (96K/192KHz) in hi-fidelity  
playback. This is also usually the behavior that professional audiophiles and  
musicians prefer.  
If you still want to have the effects, you can use some editing software (Ableton  
Live, Cakewalk, CoolEdit, Soundforge, etc.) to convert the sounds into 48KHz files.  
Please note that the frequency meter on Xonar DS Audio Center panel will not take  
effect either when the playback source is 96KHz or 192KHz sample rate to prevent  
any processing distortion.
