For a much more complete technical explanation of how the Power Plant does the voodoo it does, I suggest visiting PS Audios website or reading the SoundStage! review of the P300. But in short, the P600 is a 600-watt AC power generator that produces new AC line voltage. The Power Plant provides surge protection and is fully regulated -- so no matter how low or high your voltage supplied by the power company, the P600 provides 120 (or 220, as required) volts AC. It accepts the AC wall voltage in either 120 or 220 volts AC, steps this up (domestic) or down (foreign) to 143 volts AC, and then steps up or down through the use of a balanced transformer. The AC voltage then passes through a 50-amp diode bridge for rectification, and is then filtered by a bank of 3300mF 100-volt capacitors. This forms the DC power supply. This power supply produces 130 volts DC and is applied to two power-amplification stages. These class-AB stages are fed by a sinewave oscillator, which has an input frequency selected via a front-panel control. There is also the MultiWave option to use a mixture of frequencies, and thus improve the power produced even further. The pure 120 or 220 VAC is fed to eight hospital-grade AC outlets. There is an IEC AC input so you may use a choice of (non-filtering) AC power cords, and there is a binding post for a separate ground.
