I have Marantz AV7701 and tried to run Audessy XT room correction and it says my center and left channel is out of phase. I double checked with Ohm meter and I'm not.
Even if I do reverse polarity and rerun Audessy it still says left channel out of phase.

Is there something wrong with my soundbar?

Hi Canopy,
No, there is nothing wrong with your soundbar, that I know of.
There is something wrong with Audessy. This happens more times than you would believe.
It is just one of several problems that software has.
Don't worry, be happy and enjoy your tunes.
God Bless,
Wayne

Wayne is correct. Make sure you have wired the three channels properly (+ to +, etc.), adjust the bass management settings and speaker levels as per the owners manual (override Audyssey settings). Play the system for a while to break-in, adjust the sub's volume to taste. Might want to try without the Audyssey too, pretty strong agreement that it is more likely to hurt than help the sound.

I'm going to ditto what Wayne and the Moderator said. Every time I have ran Audessy it has said something is out of phase. This has gone on for years with different receivers and different speakers.

Ok thanks for the quick responses guys. The bar sounds awesome without Audessy so no worries there. I like to use Audessy for EQ'ng my subwoofer. I have a troublesome room with some peaks in response where sub bass is concerned. I ended up running it anyways with the errors and yeah I like the sound bar better with it off.

Btw, kudos to GoldenEar for building a quality piece that doesn't make me miss my full size Paradigm Studio V5 setup too much.
