[QUOTE="John Roberts, post: 66733, member: 126"] Re: Looking for budget bass amplifier advice While PFC is a premium option in power amplifiers, it can make a difference in how much power you can pull from undersized mains distribution wiring. Since PFC spreads the current draw over the entire mains voltage waveform, the peak current and therefore the maximum I x R wire voltage drop is noticeably less. So all things equal the PFC amp will deliver more power from the same mains outlet. I can imagine this making a difference at gigs with less than optimal mains power. JR PS: Indeed PFC is a major concern for large scale utility power distribution and many consumer products are already PFC. Europe which has been dealing with marginal distribution infrastructure for years is stricter about PFC. In the US there was a concern about large scale replacement of incandescent lamps with CFL, as the former look more resistive than the later. But his can be dismissed as a concern in the short term since the CFL lamps draw so much less total current. [/QUOTE]
