Delaying relay to block pop noise of your amplifier


delayed relay circuit“Thump” or pop noise will be an annoyance when you turn your amplifier on/off, you can’t do anything good to remove the pop yourself like modify circuits..etc. Here is a circuit that i designed for my 5.1 amplifier, because i was having trouble of a very loud “DUPP” sound through my subwoofer everytime when i turn it on, the posted circuit is almost simple, and will give you 5 seconds of delay to turn on the output of your amplifier,

NOTE: C1 and R1 decide the time to turn the relay on, i used 47uf for C1 And 100k for R1 to get 5 Seconds, you can change the value of C1 for different timings and the output (to speaker) of your amplifier must be connected to relay and relay’s output should connect to speaker.. Goodluck
