Fronts are labelled "pre" in amp assign using both presets.I have the 3800. There are two audio presets and lots of functions are fixed by the preset - check that the pre-out assign functions are not getting turned off when you change Fron

May be try flipping between assign to pre outs in and out a few times, even 10 times, each time you should heat the click sound. I think the relay might be getting stuck or the contacts got a little dirty, somehow so excercising it might help. I doubt that is the case but just being hopeful, wishful thinking on my part.Yes. Pre out assigned for both front speakers set to small. This unit has been working fine for a couple of years. This problem started a couple of weeks ago.
Might be worth resetting to factory defaults:Peng, I'll try that when I have time. Thanks.
As a temporary solution, I took the outboard amp out of the system, and I'm running all speakers from the AVR speaker outs. Sound quality not as good, but at least it works.
One odd thing though is that while this problem was occurring, when the mains were working intermittently, the system was sounding much better than usual, and the volume gain was markedly higher at a lower levels.
Any chance this is a software issue? Can I reinstall the firmware?
Anything is possible so restoring FW is worth the try, just don't be too hopeful on the outcome..Peng, I'll try that when I have time. Thanks.

Thanks for all this. I did try all the variations of resets etc. to no avail.Anything is possible so restoring FW is worth the try, just don't be too hopeful on the outcome..
Other things you can try, just to troubleshoot a little more could include the following, not in any particular order:
a) When the fault happens, measure the pre out voltage and see what's happening, obviously you need a multi tester for that.
b) Try another external amp that you know for sure is working perfectly.
c) Try a different interconnect cable that you are sure working perfectly.
If I understood right, you had already disconnected the external amp and is now using the Denon's amps that are working fine. So the troubleshooting steps above are something that I would do for sure, even just to satisfy curiosity.
Q:
1) When you lost the FL/FR pre out did both channel went silent all of a sudden, or there were some other tell tale things?
2) Did you try turning if off, unplugged the power cord and then restart the unit to see if it cleared the problem?
3) Right after you do your last hard reset, I assume you meant microprocessors reset/reset to factory default conditions, did the unit work perfectly again right after, and that the same intermittent fault only came back later, like shortly after, of long after?
4) If you hook the ext. amp back on, but still have the Denon's amps connected and the speakers connected to the ext. amp, would you still get the intermittent fault?
I think 4) is important to know, if the problem goes away then you know (99% certainty) the AVR is not the problem.
Intermittent faults are often caused by connections issues, the fact that the unit is working fine with the Denon's own power amps, would indicate that there are no parts/hardware failure, not likely anyway; and software/FW related troubles are, while possible, highly unlikely. So I highly suspect it is a connection related issue. If it is intermittent, it is not easy to find so if warranty has already expired, you should contact Denon and see if they would agree to still take it in or warranty (they may agree to do it if it has only recently expired), and if not then it may be better to wait until the issue became permanent before sending it out. That would be another reason to do more troubleshoot now as suggested above.
Thanks for all this. I did try all the variations of resets etc. to no avail.
I need to work on the problem a bit more. Right now with all speakers connected to the avr with no outboard amp, it seems to be working OK, but I want to give it some time to see if the issue resurfaces. As you say that would provide some information.
I also need to analyze what causes the mains to stop working- it seems to be changes in certain settings (i.e. speaker presets from 1 to 2 and back or changing the volume) on the avr that cause it, just not sure which particular ones just yet. This suggests that it might not be the amp or the cables, but it's something related to the pre outs.
We'll see. Thanks for the tips
