What I did - ran all the power cable on one side of Rack All audio and video cable on other side , I also a ground loop and it’s gone ... My headache is gone ! Thanks for everyone’s help. Sent from my iPhone using Tapatalk

I have also tried just the subs no other inputs same issue. I did buy a ground loop isolate for the sub out from amazon arrives tomorrow . Issue really became vivant when I added new rotel amp RMB1075. Even with just new amp hooked no noises. I have tried every single combination I could think of abs it all circles back to sub pre out .

I have found the issue will do my best to explain . My sub out from my Marantz is the issue , I have two sub outs and both cause noise. When I plug in RCA into marantz and XLR into Yamaha sub amp I get hum however I hear it threw the whole System - centre- Fronts - subs - rears . Ceiling .when I unplug sub pre noise gone I have 4 sub amps no matter which amp I try or different cables same noise. I have tried different wall plugs , straight into line conditioner even ran an extension cord to a different wall plug . No better Not sure if my sub Pre out is bad on my marantz however 100% thats the issue. Any suggestions Sent from my iPhone using Tapatalk

Polarity has been verified it is correct. Hot and neutral correct . Next step ground isolators. Sent from my iPhone using Tapatalk

What do you mean lift the ground on the Amp ? Sent from my iPhone using Tapatalk

Right now it’s looking that way. I am checking it out today Sent from my iPhone using Tapatalk

I have direct dedicated circuits only for my amp - 2 x 20 amp plugs . Someone did tell me today I may have polarity incorrect on that circuit plugs Black and white wires reversed. Sent from my iPhone using Tapatalk

Now I am really stumped , I went out and rented high end power conditioner from a music store and I still have the same buzz . Did want to spend more money if didn’t need too. I was advised if the polarity is reversed on my receptacle could cause issues . I grounded every Amp and both my AVS 2000. Can buzz can only be heard when volume is at zero . The buzz is coming from every speaker . Don’t matter If I power other amps off still hear it . This is crazy ! Sent from my iPhone using Tapatalk

I have installed 2 20 amp circuits. Unfortunately I do not have balanced inputs. My marantz SR7011 does not plus I didn’t think I would ever go this big when I originally purchased my AMP a year ago . I have everything installed however still getting some buzz , little noise appears to be coming from my Marantz main app which is filtering through the whole system. I do have a new electrical panel which was installed in my new home I do believe everything is grounded properly as per electrician. I was hoping my new AVS 2000s would illuminate the buzz the noise and however it’s not the case. I upgraded all my cables now little stumped how to proceed. I hope I don’t have an issue with the amp however it is brand new Today I’m gonna try a process of illumination where I’m going to unplug everything and start plugging in one item at a time until I hear some noise Sent from my iPhone using Tapatalk

I bought monster AVS 2000- bought it on eBay for 240 plus 50 shipping I am hopping this can run 6 big amps . I have noises and can hear it . Sent from my iPhone using Tapatalk

I am looking for a power conditioner, to clean up some noise . I do have 6 fairly large amps . Any recommendations? Sent from my iPhone using Tapatalk

It’s in perfect condition. Thanks Sent from my iPhone using Tapatalk

I picked up rotel RMB 1095 would like to know anyone’s thoughts on who owns one. I’ll be using it to power up my rear surround rf7 and RC7 This amp looks like a beast balanced inputs and weighs about 65 pounds 200 Rms x5 Amp estimated to be about 10 years old and I paid $800 Canadian Sent from my iPhone using Tapatalk

Thanks for your explanation which makes sense now I understand how I can better help my situation. Very interesting technology and I am glad I asked the question , I’ll shoot them a message explaining my system and problem. I am using Dayton U18 ultramax .i had a cabinet shop cut me the wood . They did a perfect job , I insulated inside and painted . The amps are Yamaha p7000 each running 4ohms mono - 2500 watts into each sub . Each sub as per specs move 6 litres of Air each thrust. Reasonably priced bought from parts express. The bass is so tight and thumps your chest. Watching movies is epic especially horror movies .

Hi appears your link won’t open . What’s your thoughts on 4 foam? Sent from my iPhone using Tapatalk

I bought a new home however the Rec room came finished so I had to work with what was already built . I started with Klipsch in-wall speaker all around and soon enough ungraded . Now I have an issue with my neighbor complaining about bass - the houses are at least 20’ feet apart . Plus both houses are all brick. It’s like having a Ferrari and you can only drive it 40 MPH. I decided to buy 4” foam high quality 12X12x4 - I did notice I have to turn the subs down - deeper bass and way tighter and I can’t hear anything in the room rattle , all walls are drywall and finished ceiling . My system : Maranta SR7011 Rotel RB1091 x 2 running the fronts Yamaha - P7000. X4 running subs mono Dayton U18 - x4 . Custom built boxes. RF7I Fronts - with modded crossovers FR7 sides - no mods RC7 - no mods R800 surround back Ceiling -Energy - 6”. Need to upgrade to CDT 5800 Optoma 4K 135” motorized screen . Sounds really nice , now on a mission to stop bass leaving my house . Sent from my iPhone using Tapatalk

That’s a good deal , would you happen to know how close they would sound to CDT 5800. ? Sent from my iPhone using Tapatalk
