Abstract:
An audio amplification device for amplifying an input audio signal with power from a sine wave power source, the device comprising:input terminals adapted to receive the power from the sine wave power source; a rectifier electrically connected to the input terminals and adapted to convert the power from the sine wave power source to a rectified sine wave signal; an amplifier electrically connected to the rectifier and adapted to amplify the audio input signal using the direct current power signal, the amplifier having an operational power draw up to a maximum power draw; a low current power factor corrector electrically connected between the amplifier and the input terminals, the low current power factor corrector sized to provide a first output less than the maximum amplifier power draw of the amplifier; and a high current low power factor rectifier electrically connected in parallel with the low current power factor corrector between the amplifier and the input terminals, the high output power factor bypass adapted to provide a second output to supplement the first output when the amplifier power draw exceeds the first output.
