Reply To: Hum from center pyramid

[LourdQ]

I also have a him issue that seems to have popped up only recently. When it first arrived everything seemed to function as should. The him is definitely a grounding him tone, and seems to attenuate all the other signals. Except for noise, all other segments in the pyramid have the same hum even when no other pad is being touched. I’ve swapped AC adapters but doesn’t seem to help.
