- If you followed my other thread you may know I was debating between a Yamaha Aventage and an Outlaw 976. I settled on the Yamaha. In setting it up I got an out of Phase error on one of my speakers and can't seem to resolve it. A bit about my set up. I got a Yamaha 2070. I use the Pre amp outs for the main 5 speakers and use the Yamaha amp for the Front Presence Speakers and Rear Presence speakers. My main 5 speakers are Martin Logan Electrostatic speakers. The fronts are Bi-Amped, the rears are Bi-wired. As I type this, I realize I could now bi-amp the rears as well using the yamaha amp but that is for another day What I am trying to determine is, if it's something in my setup that is causing the Out of Phase issue or a bad 2070.
The speaker giving me the error is the one of the rear bi-wired speakers and the trouble maker is the one that does not have a wall behind it for the added reflection the electrostatic speaker craves. It's open to my dining area so the nearest back wall is maybe 15 feet farther than the other rear speaker. It's entirely possible this is what is causing the read error on the YPAO software and giving the out of phase error.
Things I have done:
1: switched black and red wires in all combinations for bi-wiring.
2: Eliminated the bi-wire and only wired the top 1/2 of the speaker. Still got error in both wire configs.
3: Installed a non-electrostatic speaker and re-tested with wires in both positions.
Did not get the issue with the past set up and have not changed amp or interconnects.
What I have not done.
1: Run all new wire (seems overkill given it worked fine in the past)
2: Have not changed amp or interconnect Maybe I should just swap left and right and see if the error flips speakers.
3: Have not contacted Yamaha yet, thought I would try this forum first.
I am also not sure of the real-world impact of a rear speaker being out of phase for movies. I'd prefer not to send this beast back for service if I don't have to as it would leave me w/o a receiver and the expense of sending it back would not be cheap.
What say this forum?
