Hi all,
I'm looking for a bit of advice. I have just moved into a new house and am experiencing constant EMI (think that mobile phone interference) in my Yamaha NS7s. It is constant and is present once the speakers are turned on, even without any connections. I have troubleshooted a number of things:
1. The EMI is only present in my room. Plugging in the speakers in the other bedroom in the house and all other areas (living room and kitchen) has resulted in silent speakers, not the constant interference.
2. As stated above, it is not an issue related to balanced or unbalanced cables, as the noise is present even when disconnected.
3. The EMI is present from both plug sockets in the room, whether connected to an extension lead or directly in.
4. Using a long extension I could also rule out a grounding issue. Connecting to a socket is an adjacent room the EMI was not present, but came back when walking with the speaker into my room.
5. Turning off Wifi in the house and anything else I could think of made no difference at all.
So, I am at my wit's end with this. Apart from not being shielded by design, the speakers work absolutely perfectly.
I am wondering if anyone has any advice on how to get rid of this noise from the speakers. Putting tin foil around them has made little difference. For clarity, it is a small house at the end of a terrace in a city centre.
Also, the fact that this interference seems only to be in my room (I sleep here too) has made me a little worried healthwise. As far as I know, there is no proven health risks regarding EMI though.
Cheers for reading this.
