I recommend you to make a Simple speaker delay circuit. Imagine you finished a normally OCL power amplifier. Every time you turn on within the first 3 seconds. You may…
It will prevent the speaker from too over high power output may speaker damaged it use transistor and relay cut off as safe.
This is overload protection for transformers and load, is simple circuit cut off-on by relay. And so fast switch witch SCR driver. can set sensitive by VR1
The simple audio signal overload protection circuit. Why use it? it will protect input of power amplifier away high amplitude, more than1Vrms. Easy circuit!
I like to collect the circuit diagrams. Because when I want to create a great project. Sometimes, even we check it well. But it does not work. The good solution…
