willland Posted November 13, 2015 Share Posted November 13, 2015 Yes. Living in Florida we have some crazy lightening storms and I have to do it quite often. I also unplugged everything else. Bill Quote Link to comment Share on other sites More sharing options...

jason str Posted November 13, 2015 Share Posted November 13, 2015 Unplugging the power from the sub should not harm anything while its hooked up, no different than turning it off. Personally i power everything down if I'm unplugging anything in the system just in case. Quote Link to comment Share on other sites More sharing options...
Paducah Home Theater Posted November 13, 2015 Share Posted November 13, 2015 (edited) Might depend on the amp more than anything. You could potentially get a big POP which could potentially damage speakers. This is why sequencers exist. Unplug or even turn off a MiniDSP with everything else being on and apparently this will happen.

jason str Posted November 13, 2015 Share Posted November 13, 2015 Not the same thing. If we are talking about input cables then yes but just unplugging the power should not harm anything. 1 Quote Link to comment Share on other sites More sharing options...
willland Posted November 13, 2015 Share Posted November 13, 2015 Not the same thing. If we are talking about input cables then yes but just unplugging the power should not harm anything. My apologies, I thought you meant power cord. If RCA, then things "could" go awry. Not a good practice. Bill 1 Quote Link to comment Share on other sites More sharing options...

Pull the plug and they'll do the same thing. Lots of amps have relays and soft start circuits so during normal use you'll never hear anything. The question is more about whether it's damaging or simply annoying even if this does happen. Typically I imagine it's simply annoying, especially on subs. The red spade audio blog from Paul Spencer is excellent and if he says an amp can thump when turning off or losing power, I'm not sure why anybody here would question it.
