6.6 FlexBass

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 filter out the bass signals from small speaker channels and redirect them all to the subwoofer or Large speakers.

No Item Description
1 On/Off	Click this switch to turn on or off all functions on this FlexBass page.
2 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 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.

4 LFE Crossover Frequency	Adjusts the cut-off frequency (50~250Hz) for LFE (low-frequency effects) signals. Xonar DGX will filter out the bass signals below the crossover frequency from small speaker channels and forward them to the subwoofer. The higher the crossover frequency, the more bass signals will be subtracted.

6.7 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. Speakers and microphone are low distortion (max. THD < 2%)
2. Flat frequency response between 300\~4KHz
3. Use omni-direction electret microphone with >=40dB sensitivity
4. 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.

No Item Description

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 96KHz/192KHz content.

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.

Q7: 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 in that situation, simply turn off the "monitoring" function on other analog input devices.
