HI ALL;
kindly help me to design a circuit to detect(supervise)the output of audio amplifier.
the case is :there is for example 10 speakers concocted to the output of audio amplifier and i need to monitor this line for open circuit or short circuit or amplifier power off .
what i need is when the signal is active(music on or volume high or low or mute) a certain relay will activated on this circuit and when there is open circuit or short circuit or amp power off the relay will deactivate .
the main problem is ,the output of the amplifier is varying with the amplitude of sound ,i.e when volume increase the relay activate and when volume decrease the relay dectivated although there is a signal already exists ???
Thanksss.
