Simple delay on speaker
If you are building a normally OCL power amplifier. You will hear sound "tlub.." on your speaker. That is not good for your expensive speaker. Also, You also feel annoyed by this sound. Here is how you can do. It is a Simple delay on speaker. When you turn on the power amplifier system. A relay in this circuit will cut off a speaker before. Then, Time passed for about 3 seconds, the relay will pull in the speaker to the output of the power amplifier. You will listen to music normally. Which this sound is sound the electricity will…
