Ok - I did not try disconnecting the top left speaker again yet. I asked a buddy of mine who works setting up AV systems and he recommended this: www.amazon.com/gp/aw/d/B00145EVJ6?psc=1&ref=ppx_pop_mob_b_asin_titleI was powering the whole system from one outlet. I moved the cable box, media PC, Smartthings Hub and a switch to it's own outlet off of a battery backup and surge protector. The XMC-1, all amps, turntable and fans are now run off of the Furman power conditioner and that is plugged into an outlet that is off of a different cricut. The buzz was there as soon as I powered everything on but it is now far more faint. The buzz then stopped after about 15 min and has not come back on yet. If it does I will go back to taking a closer look at the top left speaker. |

Is all of your audio equipment in the same rack and we are just talking about speaker wire runs to the patio or are the patio amplifiers in an different area connected with audio cables?

Everything including all amps are in the same cabinet. No buzz in the main system, just Zone 2. The Y RCA cables from the XMC-1 to the pair of A-150 amps are about 2' long and I made sure they are not touching any power wires or speaker wires. The speaker wire runs to the outdoor speakers are about 50' to the screen room speaker pair and about 20' to the outdoor bar speaker pair. |

Do the speaker wires run parallel to/or with any house electric wiring?

Check wall warts & dimmer switches- unplug all in all your rooms then have someone plug them in one at a time. (stot in the dark since I can't be there to help)

Do the speaker wires run parallel to/or with any house electric wiring? They sure could. The home is about a little more then a year old and the builder had to run the speaker wire and part of the builders contract. I took some photos before the drywall went up and it looks like there are no long runs with the speaker wire too close to any electrical wiring. It is a much smaller gauge speaker wire then I would have liked to use. The covered porch was added after the home was built and that contractor moved one of the speaker wires over some behind the siding and then it runs behind a board that is secured to the house. I wonder if the speaker wire could have been hit with a nail or something like that. If I can't fix the buzz I may run new higher quality speaker wire. I can run it out to the outdoor bar and then push it under the siding along the back of the home to under the screen room. Not looking forward to that project if I can avoid it. Thanks for the helpful question. |

Perhaps I missed it, but hook up a different pair of test speakers at the end an see if the same thing happens?? |

Got to thinking about a 60hz noise I had in my sub. It was the RCA jack outside negative conductor (ground) on the circuit bd had a bad solder joint, probably from pushing the cable into it.
Wiggle your cables (gently) while they're connected & turned on, have someone listen for the noise outside..Good luck!

Perhaps I missed it, but hook up a different pair of test speakers at the end an see if the same thing happens?? It's hard to nail down because the Buzz comes and goes and I have not been able to correlate it to anything definitive. I switched the amps and the the RCA cables and the speaker wires around. The most common constant is the left screen room speaker. I never got the buzz with the left screen room speaker wire disconnected from the amp. If I get the buzz again (and I am guessing I will) I will switch the screen room speakers and then disconnect the left screen room speaker wires from the amp. If I get the buzz then I will conclude I have a bad speaker wire run on the left. If I don't I will plug the left side back in to the amp and unplug the right screen room speaker wire from the amp. If that results in the buzz I will then replace that speaker. |

I had not gotten the buzz in a while but then had to pull the cabinet away from the wall to hook up a new Roku Ultra. After pushing everything back the buzz was there again. I pulled the cabinet back up and got some foam egg crate and put all of the power cables down on the floor and then put a strip of the foam egg crate on top of them and then put all of the RCA and XLR cables on top of that foam and then put another layer of egg crate down and then put all of the speaker wires on top of that. Pushed everything back and no more buzz so far but I have not run the outdoor speakers for very long. I will update if anything changes.
