6.6 Fle�Bass
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
lter 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 lter 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 specication.
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.
3 Picture for Small/
Large speaker
Colors for small/large speakers are different.
Orange: large speakers
Green: small speakers
4 LFE Crossover
Frequency
Adjusts the cut-off frequency (50~250Hz) for LFE (low-
frequency effects) signals. Xonar DGX will lter 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 benets 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 oating 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 300~4�Hz
3. Use omni-direction electret microphone with >=40dB sensitivity
4. The microphone is more than 30cm far from PC’s speakers (x the distance)
and do NOT turn your speakers too loud
5. Put your microphone 20~30cm away from you (x 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 nish the voice-over-
IP applications, please remember to turn it off for normal high-delity audio
playback mode.

Smart Volume NormalizationTM (SVN) automatically keeps all music or video�TV
audio output at a constant level to reduce manual adjustment hassles inherent
with sound sources of different loudness. It allows you to listen to various content,
like MP3, TV program, DVD video and even games with consistent sound level.
The following graph shows how different signals 1 & 2 will become the same level
(for example, 10dB below full scale) after you turn on SVN. Please note that for
lower volume music 2, it will become louder when you turn on SVN; and for higher
