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.
3.
Remove the metal brackets from two unused PCI slots (You can just remove
one if you don’t need to use the MIDI board in the package).
2.
Open the computer’s case.
ASUS Xonar D2
3.2
Installing the Audio Processing Card
1.
Face the bracket of the Xonar D2 audio card toward the back panel of
your computer and insert the audio card gently into an available PCI slot.
Make sure it’s completely inserted into the PCI slot. (Warning! Do not force
the audio card into the slot. Make sure that the gold pins of the card's PCI
connector are aligned with the motherboard’s PCI connector before you
insert the card into the PCI slot. If it does not fit properly, gently remove it and
try again.)
2.
Secure the audio card bracket to the back of your computer with the screw
that you removed. Refer to section 3.1.
3.3

Connecting CD/DVD-ROM Drive (with the analog
header)
If you would like to use the physical playback buttons on your CD-ROM drive
to control audio CD playback on your PC, you need to connect the analog
cable between the CD-ROM drive and the audio card. Otherwise, you can
just skip this section and use ordinary digital CD playback on Windows.
Connect the CD-IN 4-pin header to the analog output on the back of your
CD/DVD-ROM drive with the audio CD cable which is usually included with
CD/DVD-ROM drive.

3.
Connecting TV Tuner Card
If you have a traditional PCI 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.
Secure the PCI TV tuner card in one PCI slot and screw it into the back-panel
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!

Sample Rate
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 D2 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 D2 engine will do super high fidelity sample-rateconversion with a double floating-point filter, which can reduce total harmonic
distortion (THD+N) by -140dB.

software tool that contains the following features:
•
•
•
•
•
•
•
Converts MP3, WMA, AAC (iTunes required), Audio CD, WAVE into WMA or
MP3 files with the same ID3 information and post processor effects
Adds Dolby Headphone processing to regular music content for a better
listening experience over stereo headphones
Adds Dolby Virtual Speaker (w/ Pro-Logic II) effect to regular music for virtual
5.1 surround over stereo speakers
Normalizes the volume level of your music collection with Smart Volume
Normalization (SVN) effect
Provides Analog Loopback Transformation (ALT) technology for high-quality
(118dB SNR) accelerated analog recording
Supports MP3 and WMA encoding formats for 128~320Kbps data rates
(Windows Media Player 10 or later version and MP3, WMA codecs are
required)
Supports transformation speed up to a maximum of 40 times of the normal
playback speed (High Speed mode). (The maximum speed is just for your
reference because it’s related to your PC’s performance and the sound effects
you choose to add. Using ALT recording technology will be limited up to 2X
speed on Windows XP. On Vista, the speed will be currently limited to normal
1X all the time.)
•
As of this writing, iTunes is not available for Windows Vista. As a result,
converting iTunes music on Vista is not supported.
•
If you are going to convert copyright protected music with ALT, you must
have valid and legal right to access and play the content. PMP is just a
software tool to record the playback analog output signal. Please be careful
to abide by the agreement with your content provider.
Before you use PMP software, make sure the following items have been
completed:

Answer:
No, PMP software is not able nor intended to decrypt DRMed content. It’s just a
software tool used to record the analog output signal from the line-out and then
convert it into WMA and MP3 files. If you have Windows Media Player 10 or iTunes
DRMed music, you are required to have the valid digital rights to play it, so that
PMP can record it from analog output just as any other software recorders. Xonar
D2 provides Analog Loopback transformation (ALT) technology to accelerate the
playback speed (2X, only on Windows XP) and record the accelerated analog
signal. PMP will convert the signal back to the normal speed with very high-quality
(118dB SNR), low distortion (-108dB) time-scaling algorithm. ALT technology can
shorten the total conversion process. Please refer to the graph below:

Q8: What's the application of "S/PDIF in loopback"?
Answer:
"SPDIF in loopback" is the process of looping back the sound card's S/PDIF digital
input signal directly to the S/PDIF output. It's useful mainly for two purposes:
•
•
transforming electrical signals from coaxial cable to a fiber optical cable, or vice
versa.
using the PC as a SPDIF bridge (typically as a media center): for example,
connect other devices like DVD players to the Xonar D2’s S/PDIF input and
then connect its SPDIF output to an AV receiver or decoder. When you would
like to send the player device's audio to the AV receiver, you need to have the
Xonar sound card's "S/PDIF in loopback" enabled to redirect the player's input
signal to output to the AV receiver.
Since "SPDIF In Loopback" is the hardware’s high-fidelity pass-through path, not
all sound effects will be applied to the signals.
Q9: 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 Dolby
Digital Live or DTS Interactive encoding output from the S/PDIF out menu, which
will allow the Xonar D2 to deliver 5.1 surround sound for games, DVD movies, and
even stereo music.
