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.  
Open the computer’s case.  
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 fit properly, gently remove it and try again.)

3.  
Secure the audio card bracket to the back of your computer with the screw  
that you removed. Refer to section 3.1.  
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 first, then unplug it from the power connector as  
the following pictures show. Do not forcefully remove the header from the power

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

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 DX audio 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 DX 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.

AEC (Acoustic Echo Cancellation)  
Xonar DX provides advanced Acoustic Echo Cancellation (AEC) for best voice  
communication quality over your speakers. AEC technology can eliminate up-to-  
40dB speaker echo return and suppress noises into your microphone for easier  
conversation experience. AEC is an innovative feature to make Xonar DX the  
best sound card choice for online chatting in VOIP applications (Skype, MSN,  
Google, QQ, etc.) or online gaming. AEC provides the following benefits to you:  
Reduce the voice acoustic echoes like speakerphone devices when others talk  
to you on line  
Minimize the playback sound echoes into your microphone during gaming or  
music playback  
Effectively suppress background or system noises into your microphone  
32-bit floating point algorithm providing precisely adaptive echo cancellation  
performance up to 40dB  
Supports all VOIP applications and online games  
To achieve the best performance of AEC function, the ideal system requirements  
are as follows:  
1.  
2.  
3.  
4.  
Speakers and microphone are low distortion (max. THD < 2%)  
Flat frequency response between 300~4KHz  
Use omni-direction electret microphone with >=40dB sensitivity  
The microphone is more than 30cm far from PC’s speakers (fix the distance)  
and do NOT turn your speakers too loud  
5.  
Put your microphone 20~30cm away from you (fix the distance) and do NOT  
speak too close or too loud into the microphone to avoid signal clipping and  
distortion. Enable “microphone boost” on Xonar DX audio center mixer to get  
proper input signal level.  
6.  
It’s suggested to disable original AEC function residing in some of the soft-  
phones or voice communication programs to get best performance from  
Xonar DX audio card.  
AEC function will be only suitable for bi-direction voice communication  
applications. The speaker type will be set as 2 speakers and special voice  
processing mode while AEC is applied (all audio effects will be suspended and  
those controls on audio center will be frozen.). After you finish the voice-over-  
IP applications, please remember to turn it off for normal high-fidelity audio  
playback mode.

DS3D GX (for Vista Only) and DSP Modes  
Xonar DX is introducing an innovative technology –DirectSound 3D Game  
Extensions v1.0 (DS3D GX 1.0)- 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, please enable DS3D GX on the Xonar DX audio center, and disable the  
function after the games.  
Supports latest DS3D GX 2.0 for gaming on Vista & XP  
DS3D GX 2.0 not only revives EAX and DirectSound HW effects, but also  
allows you to run EAX HD 5.0 games on both XP and Vista. It provides the best  
compatibility with existing DirectX games. GX2.0 also adds innovative VocalFX  
voice effects for existing EAX games or VOIP applications.  
Besides the abundant sound effects described above, the Xonar DX also provides  
quick Digital Sound Processing modes which are configured for typical applications  
including Music, Movies, and Games over different output speaker types. In  
addition, Xonar DX 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 DX 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. (Note: no sound effects will be applied to high-  
definition 96KHz/192KHz content.)

Select Music Sources  
Step 1 is to prepare the music sources that you are going to  
convert. You can select 2 music source folders which can be  
multiply checked:  
1) My Music – This path is locked and refers to  
C:\Documents and Settings\My Documents\My Music.  
2) Others – The default path refers to C:\Documents and  
Settings\My Documents\My Music but can be designated to  
other folder by clicking  
.
In the right side of the window, you will see all of the music  
files from the selected folders that can be converted by PMP.

RMAA Test Guide  
The Xonar DX driver CD includes RightMark Audio Analyzer (RMAA) v5.6, a  
popular software intended for testing the quality of audio equipment, be it a sound  
card, portable MP3 player, consumer CD/DVD player, or a speaker system. The  
measurements are conducted by playing and recording test signals, and using  
frequency analysis algorithms. The following provides a step-by-step loop-back  
test guide for your Xonar DX audio card.  
8.1  
Setting Up Xonar DX Audio Card  
Open the Xonar DX Audio Center. Use the settings below:  
1.  
2.  
3.  
Select the sample rate you will be using with RMAA (here we set 48KHz for  
testing 48KHz/24bit signals).  
Set analog output to 2-speaker mode (to get rid of any channel processing  
over RMAA stereo signals in the driver)  
Turn off all sound effects including Dolby, 7.1 speaker shifter, EQ,  
Environment, etc. A quick way to do so is to enable the “Hi-Fi mode” button in  
the Audio Center.

You should use an external 3.5mm line cable as follows (as short as possible) to  
connect the Front-Out jack to the Line-In jack for loop-back testing. In that case,  
please select “Line In” as the recording source on the mixer page.
