For the. Record ,their seems to be some confusion here,I can’t guarantee every buzz will be eliminated I am no expert. I just know myself and 2 other Audiophile friends can clearly hear the improvements. As the electrician said even if you have a dedicated line ,if the ground is not dedicated totally isolated ,then it potentially can share ground noise off other electrical branches .and if in a condo even much more so . I am just sharing with what worked real well myself and others.
How to guarantee to lower noise- ground loops in your system
I have been through many problem area where noise in the audio chain was a problem.
my friend Who is a Electrician solved the problem . All too many times people add a dedicated 20 amp circuit 12awg is standard 11-10awg even better lower resistance , also most important
you need a Isolated dedicated ground, this is totally insulated right back to the earth ground in the
breaker box this will dramatically lower your noise floor and remove ground loop problems .many people just put a dedicated line and think
that’s it ,not so, if you are going to go through the trouble, then for maybe $100 more the isolated dedicated ground to the dedicated circuit is a must. I can tell you without question .
my Audio has a noticably quieter background .in songs i now hear low level musical artifacts like reverb off a guitar fading cymbals and clearer seperation of instruments .well worth the effort .Hopefully
this will help others .this is a essential system upgrade .

My Electrician friend did the work and has a Masters license it is connected to both audio outlets, then grounded to the main ground in the box I believe not positive ,for sure it is much quieter and 2 other friends did the same thing with Excellent results they have World class systems over $100k with $3k line conditioners before hand.

What many people don’t realize no matter how good your equipment design is if you are feeding ground off the same circuits you can pickup noise thst is why my electrician installed a dual ground one is common ground with other chains back to the breaker ground ,the others is totally dedicated and insulated back to the box this way no chance of contamination .he has installed the same setup to several recording studios .a noticeably blacker back ground then before . |
I spoke with my electrician today anything else but your home theatre,audio system should be on a seperate lines . my dedicated line has 4 wires 2 grounds a bare wire ground ,and a dedicated insulated ground ,this Is what sensitive instruments use,sensitive hospital testing equipment, as well as recording studios.Iam very happy with the results. |
HelloTo All , I never stated this was a cure all.my electrician has wired several Music studios ,and wires highly sensitive testing equipment he stated as a 30 year Master Electrician the 4wire Dual,ground ,where one is common bare wire the other dedicated insulated ground this is the best way to get the lowest noise signal. It works exceptionally well for myself and several friends who have done this. nothing more to say I was just sharing what is installed in my Audio systems. |
I recently had awg 12 20 amp 4 wire dual grounds.installed , in retrospect less resistance I may go to awg 10 , seems many use and even awg 8 my question is I only have about 40 hours on my new dedicated line . The music seems a bit tipped up now on certain music . DoesAnyone have any experience with their own dedicated outlets and roughly how many hours for 70ft of wiring to settle in, thank you. |
