Using an Avia test DVD, I recently discovered that when I play phase test signals through the 3910's 5.1 analog outputs, the left front speaker is out of phase with the right front speaker, out of phase with the center channel, and out of phase with the left surround speaker (which is a monopole, by the way). However, all of the speakers are properly in phase when I play the same test signals through the digital coax output, and the fronts are also in phase through the 2-channel analog outputs.
I won't bore everyone with the details of how I isolated the problem, but suffice it to say that the problem is happening inside the 3910, and not in my interconnects or in my DVR.
So here's my question: Is there a simple and inexpensive way to reverse the phase of the 3910's front left-channel output? My 3910 is out of warranty and I don't want to send it to Denon if I can avoid it (and I don't solder).
I know that the simplest thing to do would be to reverse the speaker cables to the left front speaker, but then I'd always have to use the analog outputs (since then the digital output would be out of phase, which eliminates my ability to use the room correction feature in my AVR.
