Help please, I think I have RF or EMI problem

Hi everyone,
I really need help with your experiences.

My setup are :

Streamer : dCS Network Bridge
DAC : Chord Qutest
Pre Amp: Unison Unico PRE 
Power : Unison DM

Everytime I switch on air filter or certain light switch. It will create "pop" sound and sometime the music is "Muted". 
But only in certain area of the house.

I already fixed the grounding, and the resistance is 1.26 ohm.

The power cable is dedicated from the MCB panel to the system.

I separated the ground cable exclusively for my sound system.
But the problem still there.

I tried to move the air filter using different power source.
The glitch or the "pop" is gone, but if I move it closer to the the unit, I can hear the "pop" slightly.

Any thoughts?
Thank you so much in advance
Kind regards,
Nick

Hi All,
Latest update,

I can narrow down the issues, are coming from all the halogen light that are using ballasts.

I'm going to replace with halogen LED 

And will update.

Thank you and happy holiday

What I would first do is check all electrical point connections to make sure they are tight -- the wire connection on that light switch, pig tail wire nuts, etc., then I would go to the panel and check the tightness of the breaker/wire connections and the neutral/ground bus screws.

Make sure the ground still goes back to the service entrance.  That's a legal / safety requirement.


You might want to try moving the breaker by 1. If your switches, and light filter are on the same leg switching this can help isolate you.

I don't know what you mean by "muted." That's unlikely to be a power issue unless you have a brown out.

Maybe try using something like a Kill A watt to monitor the voltage.

I recommend it only because you can leave it in place. Of course, geeks may want to use a multi-meter instead. :)


Best,
Erik
