surround sound simulation from stereo speakers. If you have multi-channel
speakers connected, make sure to turn off Circle Surround.
Music Playback
The Revolution 7.1 can expand stereo music CD and MP3 playback into a
surround sound room-filling experience.
For surround playback for your stereo music, open the Revolution 7.1 control
panel, select the Surround Sound tab, and turn on SRS Circle Surround II. Select
the Music mode for best music playback. For more information, check the
previous section. The Revolution 7.1 is even capable of playing back DVD-Audio
discs with the proper playback software.
Windows Media Player Setup
Microsoft’s Windows Media Player 9 and later allows you to play 5.1 or 7.1 music
and movies through the Revolution. As long as the Revolution 7.1 is selected as
your default audio device, Media Player will play surround recordings through
the Revolution’s outputs.
Gaming
The Revolution 7.1 brings gameplay to life through Sensaura surround sound
playback. Sensaura uses an exclusive suite of algorithms, based on the physics
of spatial hearing, to mimic the acoustic processes that are involved in
replicating a 3D sound space in computer software. The result is a realistic
simulation of the effect of hearing any particular sound at a chosen position in
three-dimensional space around the listener.
If you have an EAX-compatible game, which supports Sensaura technology
(Windows Only), open the Revolution 7.1 Control Panel, select the Surround
Sound tab and check the “Sensaura/Game Mode” box. This mode disables
Circle Surround, and the sampling rate is automatically changed to 48000Hz.
Sensaura provides support for EAX 1.0, EAX 2.0, DirectSound3D, DirectSound,
I3DL2, and A3D. It also features Sensaura MultiDrive, MacroFX, EnvironmentalFX,
and ZoomFX technologies for increased audio realism in game play. Sensaura
works in stereo (or headphones) or multi-channel modes.
If you find that your game slows down when Sensaura is turned on, you may
want to turn off some of the graphic details or reduce the screen resolution to
speed things up.
Recording
The Revolution 7.1 includes a pair of audio inputs for recording. You can set the
input level of the inputs by launching the Revolution 7.1 control panel, selecting
