Thank you, Steve.

No dimmers or high-wattage appliances. In fact, I have a dedicated circuit then a UPS for the studio equipment.

The static is in the sound module (Focusrite 18i20) and propagates from there. Unplugging all inputs and turning off the computer does not solve it. All the cables from the Focusrite on are digital, so I think they would either work or totally fail.

I'm starting to think it has to be failing capacitors in the Focusrite.
