METHOD AND APPARATUS FOR AUTOMATIC SHUT OFF OF ELECTRONIC EQUIPMENT

摘要

An audio output signal generated by audio, audio/visual, or electronic musical instrument equipment is monitored. If the level of the output signal falls below a predetermined threshold for a predetermined period of time, then power to the equipment is automatically shut off, resulting in a state that is the same as or similar to that which occurs when the normal user power switch is turned off. The equipment may also be turned on and turned off with the normal user power switch.
