System BLUE have a HP filter that reject perfectly the 50/60Hz electromagnétic field. . The problem is the harmónics generated by arcing in the power system trought our components leaks. I have 3 power lines (two of 30Kv and one 15Kv) about 50m away from my house and with hP filter on, I have no problems! The big problems are the omnipresent switching power supply, and the switching celular chargers! Today I installed the digital lowpass filters in all channels and it seems working fine. I tuned the filter in 40Khz and much of the noise go away!
