I may be posting this in haste - I'm waiting on a 10 minute soft reset - I did a hard reset tonight, finally, and got my Denon setup menu back on screen. I went thru the Audyssey setup, and I have 2 front subs - I thought that I was adjusting my right front sub, or Sub1 - and was having a hard time of getting it into that 75db range, but it took. So Audyssey went to the left sub, or Sub2 - and this is where it gets fuzzy.
It didn't respond, or I thought it was .... but it wasn't getting to the 75db range and sticking. Tried it several times, and gave up .. wasn't seeing that sub at all, apparently. So I did another hard reset - with the subs left on, the separate power amps on the pre-outs left on, and the hd projector left on, and I believe that I pulled the Audyssey mic cord out of the Denon.
Came back to the Audyssey setup, and now it says I have no signal at all from Sub1, which is now the sub on the left - or Sub2 by rear panel connection. I check the sub, wiring and power is all fine.
I'm thinking that something got confused in the Denon setup. Or I confused it somehow. So I'm waiting for the 10 minutes soft reset, but I have a feeling that I'm going to have the same problem with that 2nd sub. Space is tight, and I'm no Houdini, so I'm trying to keep my attack on this problem to the minimum until I can get some young lithe type to get in behind the wall of gear.
Not sure if its the interconnect to the sub, and the subs are 20 years old, Velodynes - rock solid. But ... who knows ? cables and amps in subs go bad. But I'm wondering about this B-Stock Denon x4000.
Any one have any experience with this kind of gremlin ? I'm trying to think - I could get out a sound check dvd and see if there's any signal coming from that left sub, or would the denon get in the way of that ?
