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