Connecting to a T� tuner card
1. If you have a PCIE TV tuner card on your PC, you may need to connect it to
the Xonar DGX card to send the tuner card’s sound to your PC speakers.
2.
3.
Secure the PCIE 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 DGX card.
For optimum TV audio quality, Xonar DGX uses ADC recording to digitize the
signal and loops it back to DAC playback. Select Aux-In as the recording source
in the Xonar DGX 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 5.1
channel surround sound in any set of headphones. TV audio on your PC will
become even better than on your TV set.

FlexBass, an advanced bass management and enhancement mechanism, allows
you to select each satellite speaker’s type for optimal sound performance from the
speakers. (Small: common speaker that cannot produce low frequencies; Large:
wide-band speakers that can produce low frequencies well). It comes with an
adjustable crossover frequency for the boundary of the bass signals. FlexBass will

option
Select the speaker type that you connected. If your speaker
type cannot perform low-frequency signals (bass), select
“Small” speaker type and Xonar DGX 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.

AEC �Acoustic Echo Cancellation�
Xonar DGX 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 DGX 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 300~4�Hz
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 DGX audio center mixer to
get proper input signal level.
6.
It’s suggested to disable original AEC function residing in some of the
softphones or voice communication programs to get best performance from
Xonar DGX 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 and DSP Modes
Xonar DGX 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 DGX 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 DGX 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 �6�Hz�1�2�Hz content.

ASUS Xonar DGX
Q2� �hy does the Xonar DGX support Dolby® �eadphone?
Answer�
Dolby is the ONLY brand and technology recognized by the CE industry and
available on a wide range of audio equipment. Xonar DGX includes the feature to
make your PC a powerful media and entertainment center.
Q3� Does the Xonar DGX support EAX on �ista?
Answer�
Yes, Xonar DGX can support the latest EAX on Windows 7/ Vista /XP through
innovative DirectSound3D Game EXtensions v2.5 (DG3D GX 2.5) technology.
Q4� �hy do I need Dolby �eadpone for PC games?
Answer�
Dolby Headphone is the best 3D sound positioning, spatial modeling and 5.1-
channel virtualization technology for regular stereo headphones and speaker
headphones.
Q5: What is the most important benefit of the Xonar DGX for gamers?
Answer�
1.
2.
3.
Headphone amplifier: Enables accurate sound positioning in superb quality
for unparalleled gaming experience.
Dolby headphone: Delivers a realistic and spacious 2-to-5.1 surround and
3D positional sound field over any set of stereo headphones.
GX 2.5: Enables the latest EAX gaming audio and restore surround gaming
in Windows Vista/7 without additional software.
Q6: Will PCM sound output through S/PDIF be just 2 channels even with
different analog output channels?
Answer�
The S�PDIF protocol specification (IEC-60�58) 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.
ASUS Xonar DGX
51
Q7� �hy can I hear and record sound from other recording devices when
�ave/Digital is selected in Record on �ista?
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.
