Quad mode is used when you have 4 speakers, to address each speaker independently.
The 2 speaker modes also send output to all 4 speakers, but the sound is just duplicated; everything that plays out the front left speaker will play out the rear left speaker – everything that plays out the front right speaker will play out the rear right speaker.
2-speaker modes are useful if you want to have two people listening to headphones and hearing the same thing. - Updated: November 29, 1999
