      Hi!
      Hope to get some great ideas on this.
      I have set up a passive speaker system with a rack mixer and a power amplifier along with a couple of speakers. I would like to power it all on with one "master" switch but since the amp powers up faster than the mixer I get some "Popping" from the speakers when the mixer turns on. Is there any way to build a delay of some sort for the mains to the amp so that the mixer turns on before the amp so I get rid of the "pop"? Would love to be able to have a "one-switch" solution for it.

        Tony,
        There are commercial power sequencers like Furman M-8S ($200) that would certainly do what you want. A lower-cost option might be to use a current sensing/"smart" outlet strip. Here is one on Amazon. Note that I have not tried these for this use, though I have used the Furman.
        You could possibly build something yourself, but the serious fire and electrocution risk means that it is better to purchase something.

        I hope this helps.

          Hi!
          Thanks for the reply. The Furman gear isn't really something I can use for this set-up. The rack mixer has it's own power converter that I can't connect to the Furman. I have, however, gotten in contact with an expert in electronics that will try to help me out.
