Interesting. I have the UMC-200 also daisy chained to 3 UPA-1's, UPA-2 and a XPA-200. They seem to all attempt to power on, go off, and then come on fully one and stay on the second time around. I'm going to try daisy chaining 2 of the UPA-1's to the 2nd trigger and see if the problem still occurs. I never had this issue when it was just powering on the XPA-200 and UPA-2. Once I had all 5 amps chained the problem presented itself. Any advice of why this is perhaps happening would kindly be appreciated. Perhaps the older amps just passed thru... |

Just trigger one and daisy chain the others with 3.5mm mono cables using the trigger in and out on each one.

Don't they have power switches? I just flip mine on one or two at a time. It takes less than 3 seconds to turn all three on. Prob do 6 in 5 seconds?

Using Arduino technology, you can build your own sequenced 12-volt triggering system with adjustable delay for each trigger. Inexpensive, effective, and programmable.

I was thinking that Uncle Taiji-san may might use the Mel Brooks left handed six finger method. ----- Pinky turns on amp #1 .......... one thousand one, one thousand two ----- Finger #4 turns on amp #2 .......... one thousand one, one thousand two ----- Finger #3 turns on amp #3 .......... one thousand one, one thousand two ----- Finger #2 turns on Amp #4 .......... one thousand one, one thousand two ----- Finger #1 turns on Amp #5 .......... one thousand one, one thousand two ----- Thumb turns on Amp #6 Bingo! TET (total elapsed time) .......... 10 seconds  (PS: Don't say TET around a Vietnam Vet!) |

This thread is getting too long. Just daisy chain the amps as I suggested up top. I have five XPA-1Ls on two dedicated 20 amp circuits. Never a problem turning them on all at once.

Are you with the TLG (Thread Length Gestapo)?  |

Yes, the trigger out on the amps is delayed from the trigger in. So if you daisy-chain them then you'll get them switching on sequentially.
If you don't want to wait for all six to come on one at a time then you could take an 1/8" mono splitter at the input to the first (say, bass) amp on one side, and then feed that on to the other side bass amp. Then take the trigger out from each of the bass amps into the mid amps, and from there to the treble amps.
In this example you'd get L/R bass amps come on, then the L/R mid amps after a second, and then the L/R treble amps after another second.
I do a very similar thing with mine so I'm not having to wait for everything to come on in sequence.
