ASUS Xonar DX PCI Express 7.1 Audio Card
The Main menu provides access to channel settings, sample rates, speaker configuration and SPDIF options. With the 7.1 Virtual Speaker Shifter enabled, the graphic on the right becomes active and allows for dragging of each speaker into virtual position for each adjustment without the need to physically move speakers. The Mixer menu contains level controls for Playback and Record settings while the Effects menu offers a 10-band equalizer that can be set to a wide array of presets or manually. There are also 27 Environmental controls that simulate playback in an Auditorium, Arena and Forest, to name just a few.

Main Effects FlexBass
There is a Karaoke menu which does a respectable job of removing vocals from music without ruining the instrumentals, and a key shifting feature can change the pitch of the song to suit the listeners/singers vocal range. The FlexBass feature allows for bass adjustments from 50HZ to 250HZ for those looking for more bass impact. This feature also offers the option for the settings to be geared to small or large speaker setups.

AEC VocalFX
Acoustic Echo Cancellation (AEC) prevents feedback and echo when using a microphone, which often occurs when the microphone and speakers are in close proximity. The setting can reduce speaker echo to -40dB. Lastly, VocalFX allows for voice modifications while chatting during games or over VOIP applications. ChatEX applies environment effects, such as Bathroom, Concert Hall, Underwater and Music Pub while Magic Voice applies voice effects, such as Monster, Cartoon, Male and Female.
