Abstract

An audio output signal (18) generated by audio, audio/visual, or electronic musical instrument equipment (10) is monitored by an automatic shut off device (11). If the level of the output signal falls below a predetermined threshold for a predetermined period of time, the power to the equipment is automatically shut off via power coupling device (16), resulting in a state that is the same or similar to that which occurs when the normal user power switch (22) is turned off. The equipment (10) may also be turned on and off with the normal user power switch (22).
