Aperion S-12 HK AVR 225 Sony 5 disc cd play Sony progressive scan DVD player For some reason I can't figure, When playing a CD in my CD player, I get absolutely no Sub action. If I put the same CD in my DVD player I get great bass. DVD player does have a Toslink connector whereas the CD player simply has analog RCA connections. Still, in all of the various surround sound modes that the HK has and ensuring that I have front speakers set to small and S/W set to Sub and not LFE. (I've even tried setting Fronts to Large and S/W to Front L/R & SUB) I get nothing coming out the sub. Obviously the connection between the sub and the receiver is good since it plays well from an optical input from the DVD player. And I get sound from the other five speakers through the analog connection from the CD player. Tell me, What am I missing. Either I am overlooking something or possibly have some sort of bad analog input connection on my HK(?) BTW. Has anyone listened to "TOOL's Aenima" CD through surround sound?
