Dear all,
I dont want to have my power amplifiers and speakers powered when I am not playing music to save energy. The switch device should both power down
I have found this following circuit Audio Auto Shutoff. Which maybe what I want.
What I want is to have the preamplifier signal switch on the power to the amplifier and the amplifier remain powered for 20-30 mins after the audio signal has stopped, then switch off.
Do people know where I can find other circuits, PCB's, or suppliers of modules for this task?
Regards
Owen
