Topic: Noise from rca interconnect cable

[BTW]

A lot of these noise/garbage actually comes thru the earth wire.. That's why some have reported that lifting the ground helps solve the noise issue... I found this out not so long ago when I changed to a new aircon .. I had to switch off the aircon to kill the noise.

For those staying in a flat or condo.. run a dedicated line straight to your unit's Electrical DB box.. That will minimise the garbage comming in from aircon etc.. For those staying in landed.. there's another option to run an earth wire all the way outside the house into the garden using an earth rod... See below page 6..

BTW, this is good info for grounding.
I think it is really the Weiduka AC conditioner that is giving problems.
Didn't have any noises coming from the system the entire of last night after switching out the conditioner.

Good to hear you identified the root cause of your noise problem... Proper Grounding can improve the sound quite a bit... Just for info there are companies like Telos, Tripoint selling expensive grounding stuff.

Perhaps a component or 2 in weiduka faulty

Hi, I m interested in the earth wire outside house into garden option, could u further share real experiences after having it mplemented into ur setup.

Thanks in advance for ur time n advices.

PS: I m already having dedicated AC line to DB box

Ideally it should be copper bars hammered into the ground star configuration. For my case not so convenient... also in my case the noise induced by the new air con was driving me nuts.. so as a temporary solution created another earth by grounding it to house's front shelter.. the metal shelter has more than 6 metal rods driven into the ground. Not ideal but ok for now.. The aircon noise dissappeared.. more quite .. more details..everything is good.. Maybe in future I'll get my contractor to hammer the copper rods thru the floor outside.. but no hurry for now as I'm getting good results.

Thanks for advices the ideal way of configuration.
Besides solving the air con noise, do u find improvements on sys sq?

When the background noise level drops you will get more better details and dynamics. IMHO definitely worth the effort to optimise the grounding of your system.

Got it, thanks again for ur advices

Got the electrician to lay the extension earthing, may I also ask if there is a way to measure if is working as is should?

Check your PM .. Thanks
