Default PA amplifier design

Hi all,
Im planning to design a 1000w PA amplifier based on SMPS. For the amplifier, the input voltages varies from 100-270v with varying frequencies ranging from 20-80hz. Will a PFC circuit be enough to supress the noises generated by these varying parameters? What all factors should be considered for eliminating noises and obtaining true RMS power in the above said case?
