Radio Signal interference


Hey all, 

Why am I gearing the faint sound of radio talk show through both of my systems ( main and bdledroom) when music is not playing? I think in the main system it has been isolated to the main amp and connection to the speakers.tye sound still happens when the preamp and TV are off and amp is on.

 Associated equipment:

SOURCES: Blue sound node 2, TV, project debut carbon tt
Preamp: NAD C 165BEE
Amp: red dragon s500
Speaker Cable: Audio Magic Excalibur
IC'S: anticable level 1 and generic node 2 cable.

Hey Ben,

Are you in a high rise, or near a radio transmitter?

I don't know your cables, but try even inexpensive, fully shielded cables just to see if that is what you need. A lot of boutique IC's deliberately omit the shield to minimize capacitance.

If that doesn't work, consider a power conditioner with serial mode surge protection, such as some Furman and SurgeX. I personally always recommend the Furman's with SMP and LiFT.

Best,

E
