I'm resurrecting an old thread, but I wanted to report a pleasant surprise regarding the use of the HPF/LPF x-over setting in analog bypass mode.

Since my last post on this thread, I have been swapping my phono stage and CD player output cables between the 7.1 inputs.

Over the weekend, I hooked the phono stage back into the "AUX" input, switchhed to "BYPASS" and, though I was expecting a full range signal to my mains only, I was ecstatic to hear the sub going. So then I tried the same thing by re-hooking my CD player back into "CD," and bingo, the sub was engaged.

Evidently, if the toggle is switched to HPF/LPF, ALL analog sources played in "BYPASS" mode will activate the sub.

No more switching cables.

I am a very happy camper.
