Quad mode should only be used when you have 4 speakers connected to the
Quadzilla.  Quad mode addresses the front pair and rear pair of speakers
independently. 


STEREO SOURCES:
---------------
When playing a stereo source (non-A3D), the Quadzilla rear speakers will play
a low-level "ambience" effect, giving the impression of surround sound from
regular stereo sources. 


GAME AUDIO:
-----------
When playing a PC game that supports Aureal A3D 2.0 Positional Audio, 
the rear speakers will play A3D surround audio information from the game's
soundtrack. For games that do not support A3D 2.0, the rear speakers will
play a synthesized ambience effect, the same as when playing a regular stereo
source.
