2:44 is the best impression of a relay i've ever heard

Nice of your folks to support the competitors. Why not?

Once you live in lower California for a good lengthy time, its hard to get used to the seasons. I still get caught off gaurd even, almost 30 years later. Good Video!

Thank you!!! I am one of those folks that honestly did not know this.

Thank you! I have a 30 year old Onkyo amp and preamp but never understood why this was happening until now

One hack I know of is to place a capacitor across the 'on/off' switch or relay contacts to drown out inductive spikes when shutting off. I know I'm dating myself here - I remember when there were actually on/off SWITCHES! :)

The Dynaco PAT-5 preamp has a solution to this. The preamp was powered on all the time! The power switch was only used to switch the power amp!

Hey Paul, I have a lasting popping sound when I turn on my AMP. I have a multiroom system connected to a AMP Selector (4 zones), and when I turn it on all the Speaker Connected do a popping sound for a few minutes (around 3 to 5 minutes). It is not too loud, but it is annoying! It seems like the speaker are kind of warming up, does that make any sense? Is there a way to fix it? Cheers from Brazil, thanks for the attention!

Thanks Paul. I've got Audiolab 8000A and P and this happens if I forget to give the A a minute or so to settle.

Hi, thanks for info. I understand the that bang on turn on but i have problem on turning off the preamp. I have a speaker protection which has AC sensing to turn off it's relay(like 20ms)for disconnecting the speakers. But the poping noise of preamp on turning off is even faster than that. I just dont get the nature of pop of the preamp because power capacitors should hold voltage for 5-10 second.

I got the pop from the speakers right after I turn on the integrated amplifier (other equipment has turned on first). The pop noise is louder when the I.A. is cold but noise is much reduced (to almost none) when the I.A. is warmed up. Why is it and how can I cope with it? Thank you.

I have an issue with my amp where it’ll be completely quiet and when I turn the volume up it makes a popping noise and then I’ll here a loud haze. This happens going from -31db to -30db

So do all pre amps make a pop if ur amps on first and would I be safe by posing the amp on last so pre amp first then amp on and reverse for off so amp off first then amp will this process be safe for my speakers

I don't hear a pop from my Stellar gear when I'm turning them on (SGC first, S300 second via 12V trigger), but I do hear a very soft thump from my Elac Adantes whenever I shut them down.

I love it that you have a Shiitt Audio headphone amp on the work bench. !!!

Can popping or pop sound, can damaging my guitar pedals?? Because every time i engage my pedals it sound pop to the speaker...please thanks for reply .My pedals are new and i taking care of it. Thank you for answering.

Ok so i had a taramps smart 5k bass it went out so i bought the taramps smart 5k version well once i installed that with the taramps eq now my system pops when i turn it off.But it never did it before can sum one plz help me..Thanks..

I have a onkyo sub that has annoying popping at random and ive tried everything to try and fix it and i have no clue whats left to do other then buy a new sub which i dont want to do as when it works it sounds awesome. but at lower volume it tends to have random pops. When i play sound (full spectrum) directly to it it never ever pops so it must be related to either the receiver or the fact its not getting a input in the range it works. Only fixes online i found is getting a non auto standby sub. even tho when it goes to standby it doesnt pop but clicks and goes into standby which isnt a issue.

Hi. I have a problem with my block vr 100. When i listen to music or watch tv or KZfaq averything is ok but when i press stop button or search on KZfaq i hear loud crackles in my speakers. No one can help me with that. Problem doesn't exist on headphones

Strangely this only happens with my Alchemist Nexus cd player. If my pre amp and power amp are on before I turn on the cd player I get a pop. Never knew why. I will follow your start up advice. Thx

Sounds like you're describing a ring, Paul

One may also consider leaving their equipment on 'round the clock. The only time a preamp should really require a shut-down (that is to say, beyond one being away from home for more than a couple of days) is, either, when interconnecting signal or power cables, or if one's digital preamp functions misbehave during operation, indicating the need for a processor reboot (as Paul described -- power amp OFF at shutdown first, followed by the preamp. And, at startup, preamp ON first, followed by the power amp). Of course, purely analog rigs don't develop processor issues. All things being equal, most modern A/V equipment is designed to run reliably within a particular operating temperature range that should remain fairly constant for best performance, and leaving the system on may be of benefit in this regard. In fact, it may actually (though this may seem counter-intuitive) extend the life of the equipment by avoiding the repeated, potentially damaging power surges between voltage rails, in the same manner that leaving a conventional, incandescent light bulb on typically results in extended life (in my experience) over one that's cycled daily. Same principal, I mean. Also, for those concerned, 'green-conscious' individuals, home audio equipment left to idle typically doesn't draw that much more current than the same unit left to standby. Don't want to hear that 'pop'? Try leaving the equipment on.

I will get aloud pooping noise from time time and will lose all sound until I I restart everything. I can't figure out why it is doing it! I've seriously taxed my brain! Help

so the turn on pop is the same electrical DC signal the speakers receive for example, listening to music and movies

What's happening when you hear a pop when shutting it off?

I have an integrated DAC/preamp/Amplifier unit. It only has one power button that turns on everything at once, presumably. I get the popping noise fairly consistently in my headphones. Should I be concerned? Should I plug in my headphones after I turn on my unit?

Any suggestions for heartbeat continuous sound from 6j1 preamp, with even input disconnected. Almost 1 per second. Power input 12v AC for preamp . Thanks in advance

Switching on 1. Turn on pre amp and wait 60 seconds 2. Power amp volume levels at zero then switch on Switching off 1. Power amp volume levels down to zero, then switch off 2. Pre amp off * remember this, could save you some $ and hassles with repairs...speaking from experience :P

Mind you this is happening while I'm watching something and then out of nowhere it will happen

But how about a subwoofer with aut on,off

Yep, that's right. Most components, like caps, are charging up as the power supply rails come up to speed, etc. Just about everything will emit a voltage spike when powered up, unless, like Paul said, there is a time delay relay at the output! MOST modern solid state amps have that relay now, which also, in most cases, monitors the power supply rails and will open the path to the speakers if there is an abnormally. Now, do tube amps pop when turned on? Hmm. You wouldn't think so, because of the tube filaments have to heat up, and that's a slower process than a solid state amp, so all the voltages are sort of "ramped" up instead of slamming one way or another. Computer sound cards are terrible culprits of turn on pop! All of mine pop when the opsys loads the drivers. Plus they have no mercy when I shut down the computer! BTW, my vintage old Hafler preamp pops when powered up! LOL.

Why not keep the capacitors fully charged all the time with a trickle charge all the time in a standby mode the way a car battery charger uses a trickle charge to maintain battery voltage wen it's full charged and then when you turn it on you bypass the resistor that limits the trickle current? This way there is no thump and you can eliminate the relay. BTW which relay contacts sound best, P&B, Claire, or what and how often do you replace them?

Get home, turn on my PC, turn on my Amp/preamp. Popping noise happens. 2 mins later, log into KZfaq, see this video was uploaded 32 mins ago. Now that's timing.

I don't . . . it depends on the amps, because when I replaced the amps with new ones, the noise -- ALL of it, stopped!

you don't know . . . I do . . . . .

They make popping sounds because of substandard primitive design.

Not a complaint but lets change the ending music to something other than Peter Frampton
