Okay, I'll study the manual. But just to be sure, you do understand that the speaker menu has to be set for four speakers, not two. It's as if you're playing both front speakers and surrounds. Without studying, it would seem that Direct would have to take all four of the analog inputs and without any processing send them out after amplification through the front speaker and surround speaker terminals to the front and back drivers.

Enjoy the music, not the equipment.
