A.S.P. (Automatic Speaker Protection)
This circuit monitors the output and input of the amplifier. As the output reaches close to the limit of the power supply rails the input is instantly reduced to prevent the amplifier from clipping. The dynamic range of the amplifier is not compromised as the circuit has been set to activate at a point beyond the full dynamic range before protection is activated.
