[QUOTE="John Roberts, post: 101430, member: 126"] Re: Behringer iNUKE NU6000 amplifier Nothing very practical. Harmonics in the mains wiring is caused by how the current is drawn (non-sinusoidal) interacting with the wires resistance. A Passive solution is to use heavier gauge wire (not practical). Adding reactance to the mains wiring can smear and spread out the current peaks, but may limit power transfer. A free standing PFC between the mains and the amp, capable of delivering adequate current would not be a cheap product by itself. If needed, building it into the amp is cheaper than stand alone. Years ago it looked like PFC would be mandated for all power amps (sold into EU zone) and all the major amp makers developed the capability. Since then the legislators backed off, and only a handful made it into production. JR [/QUOTE]
