Does the Synergistic Power Line Conditioner do anything else besides suppress high-frequency noise?
Despite the belief of many critics that a power-line conditioner is simply a low-pass filter eliminating RFI (radio frequency interference) that would be better left to the preamplifier or power amplifier power supplies to eradicate, this is not the case. The unique, bi-directional, multi-stage protection systems of the Synergistic Power Line Conditioner will suppress RFI and its harmonics, EMI (electromagnetic interference), voltage and current transients (spikes) and minimize the effects of atmospheric disturbances. The large energy storage capacity of the Synergistic Power Line Conditioner helps to resist the interaction and modulating effects of large current-hungry appliances ensuring greater low-level resolution and a subjective lowering of the noise floor.
