Super X-Fi Headphone Holography
This system features Super X-Fi headphone holography to replicate a
high-end multi-speaker system in your headphones/headset. However note the
following:
1. X-Fi audio technology will be the default audio control for headphones/
a headset plugged in to the 2-in-1 (Headphone/ Microphone) audio jack,
therefore volume levels are only controllable by the Windows volume
controls and not the Realtek Audio Console or Sound Blaster Atlas control
panel.
2. The default volume level for the connected headphones/headset is set at
69%. If the volume level is increased above 69%, upon restart the system
will revert to the 69% default level. Any decrease in the volume level lower
than 69% will be retained after restart.
