Need help identifying parasite noise

[John Trieu]

Hi there,

I'm new to the forum and the audio world, please indulge my amateurism.

I spent couple of days checking YouTube videos before someone recommended me to ask the question on a dedicated forum, so here I am.

Context:
I got an amplifier from Elekit (22 HYBRID TUBE AMP) and two speakers LS50 Meta from KEF plugged with cables from Zonotone 2200a with banana plugs. When the Amplifier is turned on, I'm experiencing a weird noise that goes as follow:

(The difference in the audio level is when i'm approaching the mic to the speaker otherwise it is constant.)

On the amplifier, even if I higher the sound, the noise remains the same. Whether there is an audio input or not, the parasite noise can be heard. Could anyone help identifying the source of the issue based solely on that noise?

Thank you for your time and fingers crossed.

What is your input source ??

Does the noise persist if you disconnect the source ?

Try a different source and see if the noise persists.

Another thought could be power supply issues, try a different power supply or plug ps into a different outlet.

Thanks for your reply! My input source is a bluetooth from Audioengine (model B1), plug-in with RCA. I tried to plug another source with RCA to Jack.

The noise persists even with different input source. Also when there is no physical input source plugged-in.

I will try different location tonight for the power source. Will let you know.

Do you have a router located nearby? If so, move the router.

So I change the location, and therefore different power outlet but also further away from the WiFi and router. It did reduce the noise but still slightly persist but I guess I can live with that.

Thank you all for your suggestion!
