Audio amplifier turn-off control circuit |
摘要 |
A circuit comprising a transistor which, when supply is turned off, locks the output of the audio amplifier to the supply line, the potential of which is reduced gradually by a filter capacitor, so that the output voltage follows the supply voltage with the same slope, and is so controlled by the filter capacitor, thus eliminating undesired noise ("popping") at the output caused by electric transients in the audio amplifier.
