...is it possible? What is the voltage that drives a PA soundsystem? I presume it fluctuates +-5v? So if I took a feed from the speaker I could light an LED if I chose the right resistor.
Basicaly I want an LED to 'throb' to the beat, but powered from the output of an amplifier, is it possible? what calculations would i need?
Thanks.
