600W音频放大器电路 (600W Audio Amplifier)

POWER :GENERAL DISCRIPTION :
The circuit is based around LM4702manufactured by NATIONAL semiconductorsMJ11029-MJ11028 by ON semiconductors It is a high fidelity audio power amplifier. Designed for demanding consumer and pro-audio applications. You can also use this circuit with AV receivers, Audiophile power amps, Pro Audio High voltage industrial applications etc Amplifier output power maybe scaled by changing the supply voltage and number of output devices. The circuit includes thermal shutdown circuitry that activates when the die temperature exceeds 150°c. CIRCUITs mute function, when activated, mutes the input drive signal and forces the amplifier output to a quiescent state.
