Small / Large speaker  
option  
Select the speaker type that you connected. If your speaker  
type cannot perform low-frequency signals (bass), select  
“Small” speaker type and Xonar HDAV ꢀ.3 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.ꢀ 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 HDAV ꢀ.3 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 HDAV ꢀ.3  
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:  
Reduces the voice acoustic echoes like speakerphone devices when others  
talk to you on line  
Minimizes the playback sound echoes into your microphone during gaming or  
music playback  
Effectively suppresses 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:  
ꢀ.  
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 HDAV 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 HDAV ꢀ.3 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 HDAV ꢀ.3 is introducing an innovative technology –DirectSound 3D Game  
Extensions vꢀ.0 (DS3D GX ꢀ.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, enable DS3D GX on the Xonar HDAV 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 HDAV ꢀ.3 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 HDAV ꢀ.3 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 HDAV ꢀ 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 ꢂ6KHz/ꢀꢂ2KHz content.)

RMAA Test Guide  
The Xonar HDAV ꢀ.3 driver CD includes RightMark Audio Analyzer (RMAA), 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 HDAV ꢀ.3 card.  
8.1  
Setting Up Xonar HDAV 1.3 card  
Open the Xonar HDAV Center. Use the settings below:  
ꢀ.  
2.  
3.  
Select the sample rate you will be using with RMAA (here we set 4ꢁKHz for  
testing 4ꢁKHz/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, DTS, 7.ꢀ speaker shifter, EQ,  
Environment, etc. A quick way to do so is to enable the “Hi-Fi mode” button in  
the Xonar HDAV Center.

distortion music creation application  
Q7: 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 HDAV ꢀ.3’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.  
ꢂ3  
ASUS Xonar HDAV ꢀ.3  
Q8: Will PCM sound output through S/PDIF be just 2 channels even with  
different analog output channels?  
Answer:  
The S/PDIF protocol specification (IEC-60ꢂ5ꢁ) 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.ꢀ 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 HDAV ꢀ.3 to deliver 5.ꢀ surround sound for games, DVD  
movies, and even stereo music.
