Recently I have a minor issue with getting one of my XPR-1's to trigger start on the first try, it will cycle 3 to 5 times before staying on. My XMC-1 triggers a ET-3, which in turn triggers the pair or XPR-1's and a XPR-5. The LH channel XPR-1 seems to try to start and then shuts off a number of times, but eventually triggers on - this has me concerned. The RH XPR-1 and XPR-5 trigger on w/o a issue. Any ideas on how to debug? All connections (XLR Cables, separate 20amp outlets, etc) have not changed over the years in which it worked flawlessly.

Subscribed as my XPR2 has done the same thing nearly since it was new. Other than 5-7 attempts to turn on, it has been a flawless amp and one of the best SS amps I've ever owned.

Did a little debug - disconnected the speaker cables from the amp, the XLR input cable, and the trigger input, then switched on the amp. It keeps cycling on and off which leads me to believe the issue is internal in the circuits within the amp, and it must be seeing some kind of fault. These are great amps, and have held up for years of extended play, so wondering if anyone services (repairs) these beasts.

One of my XPR-1 amps would start to 'click' repeatedly when attempting to power on. A phone call to Emotiva's tech support guy suggested banging on the amp with my hand. Yes, really! I believe the amp was trying to switch between 120 and 240 volt input. This worked for a while, but eventually the amp refused to power up. Fortunately, it was still covered under warranty, however this required boxing up (only the original boxing will be accepted at Emotiva, NO EXCEPTIONS!) and shipping at my expense. I believe it was around $170 from Colorado. They did fix it, and return shipping was at their expense. I should add that my amps were not triggered to power on. |

Thanks Skiman1,
I see they have a 5 yr warranty, and mine were purchased in Nov 2013 so I hope they should still be covered. Have to figure out how to coordinate ground truck shipping if I cannot get it sorted out, as I have not done this before.

Hester, I just noticed that you have the same main and center speakers that I do, even the rosewood veneer!

Mr Skiman1 - if you have the same GR speakers, then you know that they are some darn nice Arrays, and the XPR's are a great Amp to power the beasts. The LSC center is not the greatest center channel, but can be tweaked within the Dirac set-up. They can be pushed hard with the XPR's and really come alive, and make for a incredible HT setup. Long ago I posted threads on the build of my GR's, which was no small feat, and they are long gone from GR's speaker kit line-up (only have some service parts available).
Unfortunately, my LH XPR Amp only found the "bang on it" fix stated by you and recommended to me by a Emotiva Tech to be temporary, and it appears to be a bad line voltage relay sticking between 240v and 115v. So I have to ship it to Emotiva for a repair.

I had the same issue with my XPR-2. I fixed it by plugging it in directly to the 20 amp wall outlet rather than the power supply I had in my rack. I watched it jump between 120-240 volt and then it would freeze up and not turn on. Once I plugged directly in the wall it stopped cycling between the two. I can only guess the power supply was varying the current(?) and confusing the switch. I could be describing what is occurring incorrectly but that was the jist of it.

Both my XPR-1s are plugged directly into separate 20 amp wall outlets, and still had the problem on one, but not the other. After the factory repair, no problems since.

I've tried every fix mentioned here, short of hitting it, and it still has switching issues.
Only got a year or so left on the warranty. I'll probably take it to a local shop that does a lot of high end gear.
They have been a McIntosh preferred vendor for many years and I trust their work. Also fixed a Mc amp for me 6 years ago.

Using the remote turn on lead. The voltage lights keep toggling back and forth on the back of the amp as well.
Defaults to 240 then when it attempts to turn on, jumps to 115 and then shuts down. Rinse and repeat.

Usually takes about 6-8 tries before it seems to "take" Started doing this after I owned it for a few months. Never bothered to ship its 100 lb butt in since it does eventually turn on. lol Scott |

I would be tempted to take off the trigger and manually turn that second amp on and off. Then again, that may be a huge painus in the anus. Tim |

Must not be a one-off. I played hockey with a Guy named Carl Idzinski. For the first five years I knew him as Rick Cabrera. When I finally found out it wasn't his real name I questioned him. His answer was that he never liked his dad and Rick Cabrera just rolled off his tongue easier....no idea! |

So I dug out the original packaging, boxed it up, and took it to a Trucking Terminal for shipping on a pallet. A 5 year warranty is nice, but shipping it back (with insurance) was expensive, but worth it in my mind cause good luck trying to find these amps for resale anywhere on the used market Some I found were listed for more than what we paid for them. Anyway, working with the EM Tech, they said it was not a new issue with the voltage sensing relay going kaput, that seems to be what causes the cycling between 115v and 240v - it would be nice to just have a hard switch on the back as relays may not be the most robust item when used over time. Banging on it worked for a few times to reset the relay, but then it started cycling on it's own after a few hours of watching TV, and that was enough for me. Prob easy to fix if I knew where it was located, but not about to dig around on the circuit board while still under warranty. I'll go abuse my car in the interim.  . |

For the record for those who own these killer XPR Amps, this is what they did. They could not duplicate the issue of triggering on and off, but with a little discussion I requested that they inspect and replace the relay or whatever else may contribute to the issue. Apparently these Caps are instrumental to the circuitry that controls the voltage sensing and start up functions. And, I have also used 20 Amp Furman Power Port Controllers on my other equipment to protect against line voltage surges and or power outages (thunderstorms, etc), but not on these as recommended in the manual. They are plugged directly into their own 20 Amp outlets. So as we all know power outages and the spike of the power coming back on does not bode well for electronics. They recommend that they are unplugged during a severe storm or power outage (or at least the main power switch in the back is turned off), and I am careful to do this when I am at home and a big storm hits. Prob is, one cannot ensure this 100% of the time, and for example if you loose power in the middle of the night and it comes back on with a surge while you are sleeping, or a quick power loss followed by a immediate power reinstatement while the Amps are on - not much one can do about it. PIA to manually hit the master on/off switch's every time you shut down. Anyone run these through a Furman or similar protection device even though not recommended?"Our service technician found the following issue: Replaced c8,11,12 caps on 5v supply".   |
