Hello,
Would anyone have any theories why BOTH of my XPA Gen3 amps died completely and totally at the same time? I have tried everything, but they just don't respond.
Disconnected all cables and moved them to another room. No change. The circuit breaker seems to be in the un-tripped position.
They were connected to a Panamax MR4300 surge protector (as were other units, like the TV, and pre-amp, Apple TV, etc). None of the other units are affected. All are working fine. Just these two large paper weights are dead.
Has anyone seen this happen with their products? Only 2 and 1/2 years old.
Thanks.

Fuses blew from some sort of voltage spike even with the Panamax there ??

Agreed, creimes suggestion would be an excellent place to start.

Of course! (Hopefully fuses and nothing else.)
The chances that both amps blew simultaneously without an intervening issue with the power is pretty close to zero

Excellent advice. Start with simple. Check fuses first.

Yes there are rail fuses to check. If they are blown, replace. Hopefully they don't blow again. Since both went out the same time most likely an over current condition occurred meaning the XPAs are doing what they are supposed to do. Is there at least standby power or all dead black?

Thank you all for the great replies. I am not sure what rail fuses you are referring to. The only type of interruptor I could see is the circuit breaker switch in the back of the units. Where would this other fuse be located? Has anyone taken a photo of the location on this model amp? The two amps are COMPLETELY dead. No sign of life at all. No lights, nothing.....all dead black. |

Circuit Breaker has been pushed in to verify it's in all the way? No other cables are connected? No trigger, no speaker wires, nothing. The Halo never lights up, but I assume you've tried pressing the power button anyway? The Status LED switch is on or off? And you've plugged them directly into the outlet the Panamax is plugged into to bypass the Panamax? |

I have moved both units out to another room and tried at different power outlets with different power cables that work for other amps. No lights of any kind light up anywhere on either of the two units! They just don't respond to anything. |

Prob a dumb question but I'm guessing the rear rocker switches are not flipped down to the off position, strange how two of them just have no life at all, time to call Emotiva ? |

Yes. All very strange. I have flipped the power switches up and down several times....hoping something would happen.
I called them, but their support number is disconnected! Exactly what you want to hear when your gear is dead.
So, only able to get support through emails. They are wanting me to ship them to their location for repair.

Both XPA's worked, then next day they don't, THAT doesn't make any sense.
I would be looking at the Panamax MR4300 as the cause- maximum current rating: 15 amps.
If both amps failed, I would question if the Panamax, with everything connected, caused a current starvation (brown out).
I don't own Gen 3 amps with the new power supply design, so I can't tell you what to check, sorry.
My recommendation to everyone is two dedicated, isolated 20 amp circuits to your A/V system.
Or one 20 amp circuit just for amplifiers and one 15 amp circuit for other electronics.
I NEVER run everything off one circuit. Why? 30 yrs as an electronics field service tech, I saw line power cause P.S. failure too many times.
I'm not a Panamax fan, there are better options for high current draw loads. (no arrows or attacks, pls. My opinion) I prefer Brick Wall products.
Sorry to hear your amps failed just in time for the weekend- that sux.

I have not read yet that the “ lids” were popped and all internal fuses were checked.
Or did I miss this?
The same fuse in BOTH units could have given it up under the right circumstances. Isn’t there an IEC fuse receptacle internal to the power cords?

Its after hours so we get a recorded message from their boss telling you to leave a message. There is also a support chat available during business hours on the website as well.  |

Correct they are in Central Standard Time in Franklin TN.

As you were able to appreciate, I was not going to be our of commission for the weekend, so I moved THREE of my hearty Outlaw Audio amps into that room and connected ALL THREE to that same Panamax unit. No problems whatsoever and I have been watching movies like crazy the past few days. I actually had run a dedicated circuit for that outlet, so only the amps are really pulling any watts. The subs are on a separate dedicated circuit. I made sure that one circuit would be on one of the incoming power lines, while the other is on the other line. So, direct lines from the power box to the outlet. I think it's the crappy power supplies in this version of the Emotiva amps. But, one is on the way to them, so we should find out soon enough what failed. |

Hello, Their support person sent an email to me, stating that no internal fuses exist on this model...not sure if that is correct, but that is what they are telling me. |

Yes, you are correct. That particular number is not disconnected. BUT, the support number that is in the "thank you" for your purchase letter ( 1-877-366-8324 or 1-877-EMO-TECH) is disconnected. |

Hello, Their support person sent an email to me, stating that no internal fuses exist on this model...not sure if that is correct, but that is what they are telling me. That’s interesting because the XPA Gen3 Owner’s Manual says “ Only replace the fuse(s) in the XPA Gen3 amplifier with fuse(s) of proper value and voltage rating.” It’s certainly possible this is boilerplate language held over from previous models, but if it were me, I’d make sure before sending it back — a phone call would be your best bet. If you’re comfortable doing such things, unplug both of the amps and let them sit for a while, then carefully remove the top cover and visually inspect the inside looking for fuses, loose connectors, or anything unusual — you shouldn’t need to touch anything. Flip the amp over and do the same with the bottom plate, try to use the correct size screwdriver so you don’t damage or scratch the screws. If you’re not comfortable, and there’s no confirmation here that there are no fuses, maybe you can find a local shop or friend who can do this for you. |
