ELIMINATE AMP TURN ON POP HOW TO

I hate using mechanical relays so below is a simple 3 transistor circuit that will delay the turn-on signal for about 4 seconds with the values shown. There are several ways to do this such as using a 555 timer IC and a relay. So we need some way to turn on slowly and turn off quickly. The problem with that is that this will also cause a turn-off delay, which will cause turn-off pops. In theory, the simplest way would be to just add a resistor and capacitor to the remote line to introduce a delay. Turn-on pops are reasonably easy to solve as all we need to do is introduce an extra turn-on delay to the remote wire to the amps. Wiring the SGN21 for amplifier turn off pop is a bit more difficult than the other methods as you will need a relay for each speaker that is popping when the amp turns off.

ELIMINATE AMP TURN ON POP HOW TO

How to wire up SGN21 for amplifier turn off pop. So we sometimes end up with a system that has these pops. This will keep the radio on after the amp shuts off to eliminate the pop from the radio How to fix amplifier turn off pop. This could be eliminated if head unit manufacturers would delay the shut down of the internal electronics for a couple of seconds after they shut down the remote output.Д«ut I'm not aware of any manufacturers who do that. Similarly, when the head is switched off the DC offset disappears causing a pop as it takes a finite time for the amplifier to shut down once its remote wire loses power. There are several causes, including faulty equipment, but the most common one is due to a DC offset in the output on the head unit taking time to stabilise.ДЄmplifiers typically have a slight turn-on delay to help compensate for turn-on pops, but sometimes this delay is not long enough. But, I wouldn't swear to that.Sometimes, particularly when connecting head units to amplifiers via the speaker outputs, a loud pop or thud will come from the speakers when the system is turned on or off. In terms of danger, assuming the POP is not excessively loud, I don't think it represents a problem. If the relay is stuck closed, then you don't get the second or two of isolation as the amp is powering on. If the relay is in the circuit and working, I suspect it would suppress the 'Pop' on start up. I'm wondering if that Relay isn't stuck connected or closed. The switch is turned on, if there are no problems, the motherboard sends a Power Good signal and the computer fully powers up. The same process goes on in your computer. If there are not errors, the amp sends a 'Power Good' signal to the power supply (or whatever) and tells the amp that it is safe to turn fully on. This is to give the protection circuits time to evaluate any errors. I'm not really sure what it is connecting and disconnecting, but it creates a time delay between when you turn the switch on and when the amp actually powers up. There is a Relay that can be heard as a very faint 'click' when the amp is turned on. The protection circuit also come into play when the amp is turned on. Most modern amps have protection circuits on the output to prevent damage from shorts, etc.

I'm going to make a huge speculation here. Not too bad tbh I can live with it as it only makes the noise when first switched on

Or as an alternative, if you turn the amp of first, the turn your peripheral sources on?Д®ven when just the amp is connected to the socket on its own there is still a popДЄlso, how loud is it? Does it just bother you that you can hear it, or is it a pretty significant POP? If your amplifier has an output relay and the popping is mostly noticeable when you turn it off, the problem might be in the bias of the output transistors. Dead silence on turn on can only be guaranteed with a relay that disconnects the speakers from the power amp outputs until the system's stable, AFAIK.

I'm curious how the various pieces of equipment are plugged into the wall, and whether you are using surge suppressing power strips?ДЄll items plugged into a 4 way extension lead surge protectedДoes it matter if you turn peripheral sources on first, then the amp. You can always turn the amp on with whatever it is hooked to turned off (but still connected and plugged in/grounded) and see how the amp reacts. When volume is turned off there is still a pop If you don't hear a POP with the volume turned down, the likely the problem originates in the pre-amp stages.

If you still hear a POP, then it is likely in the output stages of the amp. When you hear the POP, were is the volume control set? Try with the volume control off.
