I just bought this receiver about 3 weeks ago. I've read through all the posts on here so far, so thanks to everyone that has provided so much great information! I upgraded from an older Sony HTIB, so this is a big improvement for me. My living room is about 15x20 and while I know people have said that the power is slightly lacking, I have to say that I think it does really well in my setup. Like I said, I just bought it and it came with a manual addendum that mentions assignability, so I'm guessing it has the latest firmware; however, I'm just running 4 HDMI sources, so I don't think it's something I need.
I do have a question though, and I haven't seen anyone else mention it. I'm using this receiver with a set of Polk Audio RM6750 5.1 speakers. I got all the wiring done and ran the YPAO with the "Flat" EQ. It sounded okay, but I wanted play with some of the settings. I got it sounding a little better, but I wasn't thrilled with the bass and I also wanted to see how it would sound running the YPAO with the "Natural" EQ. I did this and when it finished, I got the warning that my front right and center speakers were out of phase. I checked the troubleshooting section of the manual and it said that this sometimes shows, even when the speakers are not out of phase. I ran it again to see if it was some kind of fluke, and that time my front left, right, and center speakers were "out of phase". I checked the wiring and it was fine. I wasn't crazy about this sound either. I checked my sub and since I had run the YPAO with the level just under halfway, I decided to put it right at halfway and I ran the YPAO again using the "Flat" EQ. It still shows the front 3 speakers as "out of phase". I slightly bumped up the sub's volume in the receiver's settings. This time I was really happy with the sound. I made sure all speakers were set to "small" and I checked the crossover setting. YPAO set the crossover to 80Hz, but since the lower end of the frequency response for my speakers is 100Hz, I set the crossover to 100Hz.
Here are some questions I have:
1. I know the manual says that sometimes speakers can show that they are "out of phase" even when they are not. Has anyone else had this happen, and am I running the risk of hurting anything if I just leave it how it is? As I said, I checked the wiring and everything seems fine. It also sounds really good right now.
2. Should the subwoofer setting be set to "SWFR" or "Both"? I have it set to "SWFR" right now. I want to make sure that all frequencies below 100Hz are sent to the sub (hence the 100Hz crossover setting).
3. Speaking of crossovers, YPAO set mine to 80Hz. I understand that that's a starting point. According to the manual for my speakers, the frequency range is 100Hz to 24kHz, and the sub's frequency range is 40Hz to 200Hz. How much difference is there between setting it at 80Hz or 100Hz, and when would I notice that difference?
Sorry for the long post, but I wanted to get it all out after reading 43 pages of posts!
