...and just to clarify ('cause I'm pedantic) Surround A and B actually refer to a 5.1 setup with two sets of side surrounds, projecting identical signals (possibly dividing the power, don't recall) used for long rooms with multiple rows of seats. The Surround Back would be for 7.1.

And yes, my 3808 works great with my Epic 80 system.
