If you don't have a record clamp just pull the disc off of the spinning platter. Practice makes perfect.
Power Down Sequence for Amp / TT to Avoid Speaker Pop
Hello! I have Rogue Audio Sphinx v3 and Rega P3 TT and Zu Audio Omen's. When I go to flip record side or change to another record, I turn off the TT (while the amp is ON) and I hear an audible pop from the speakers.
I've heard you should avoid this pop (to protect the speakers), but this would mean I would have turn the amp OFF and then back ON whenever I change the record which would be a pain. Turning the TT OFF is the only way to stop the platter. And, Rogue advises not rapidly turning the amp OFF and ON to avoid "transient noises".
What do others do here? Is the pop something to really be worried about and worth this power off / on sequence? I might be missing something as well.

Right, there is no need to stop the platter. In fact it is much better on the motor to just let it run. But if you are going to turn it off then the way to avoid the pop is to change your input selector to something else. That is what I do in order to avoid cleaning stylus noise, zero-stat noise, demagnetizer noise, etc. |
you should develop a consistent sequence for system power up and turn off. including grounding your self prior to touching anything to drain any static charge you may carry. and that should always be turning "on" , first touching something, then from source toward the amp. then your turn off sequence should be ’grounding’ then amp to source. this sequence will eliminate turn on or turn off pops. and any time you mess with vinyl, you ground yourself EVERY time you are going to touch something. very quickly you will develop muscle memory and you won’t even think about it. now getting to your specific situation; you should first ground yourself, then ’mute’ the phono, then touch the tonearm. if you can ’mute’ with your remote, then ’mute’ on your remote first then, then ground, then touch the tonearm. if you press mute on the phono pre chassis first, prior to grounding yourself, that can be a big problem and can fry stuff. note; when you ’mute’ you do mostly insulate your speakers from any pop. but then grounding before you touch anything is even more safe. as far as what to touch for grounding, something organic is best. i touch a wood shelf on my rack. every......single....time. |
@arcticdeth - Rogue's user manual says the opposite for Power On. 1) Turn on all sources, 2) power up Sphinx, 3) select listening source and play. Then, they state the reverse for Power Down. Your sequence for me led to the pop when turning off the TT. @holmz - I still hear the pop when I turn the volume knob all the way down - though I didn't hit use the MUTE button on the remote control. |
@ millercarbon has told you what to do. Just switch to another source. No reason to shut anything off! I had the same problem and it was a bad capacitor on the on and off switch on my turntable! |
Yes, check or replace capacitor across TT on/off switch. And you are right; Amps on last and off first.Ah or maybe a flyback diode if it is back EMF? We have always done:t startup I do:
At shut down:

I use 2 different techniques: 1)Change the input selector in my preamp 2)Use the mute switch on my phono preamp It keeps the switches in good operating order. I also have a Technics tt...which stops the platter in an instant with a brake (torque that can be adjusted). Never gave it much thought until this post. Also powering the tt on/off out of sequence won't create a audible pop. |
