Abstract
Disclosed herein is an improved VCR power supply capable of selectively breaking a dc supply voltage to an audio apparatus during its audio mute state set by a control unit. The improved power supply comprises a first transistor coupled to an upstream of the audio apparatus for selectively blocking the supply voltage; and a second transistor, in response to an audio mute control signal from the control unit, for controlling the selective breaking operation of the first transistor, thereby achieving a low consumption of electrical energy during the audio mute state.
