600W Audio Amplifier

600W Audio Amplifier
author: YMYA electronics - IZHAR FAREED


Maximum Output power @ 8ohms : 300watt
Absolute max power supply voltage :?38V to ?40V
Recommended power supply voltage :?30V to ?35V

The circuit is based around {LM4702}manufactured by NATIONAL semiconductors&{MJ11029-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. CIRCUIT?s mute function, when activated, mutes the input drive signal and forces the amplifier output to a quiescent state.
