Hello Forum, my XPA-5 just suffered its second malfunction in 7 years. first time under warranty and had to send in and it was fixed. Now, its shutting down again. Emotiva has no mercy for its products here. With shipping, around 400 dollars to fix and send back. My audiophile expert turned me on to the Monolith 5 amp system.
Anyone want to buy this boat anchor for a couple of hundred bucks? capacitors I hear need to be redone, etc.
Thanks

Where are you located?

What capacitors? the BIG cans in the PS should go 20 years at least. Maybe longer.
The other caps, smaller ones on board also last an awful long time.
Big PS caps that fail in 5 to 7 years? WAY too early.

Sounds more like a bad resistor or protection circuit. Doubt it's the caps.

I agree.
But the OP DID say caps. I was reacting to that.
Does or WILL EMO part with a schematic.

Does or WILL EMO part with a schematic. Doubtful. They wouldn't when I tried to fix an XPA-1L that kept going into protect mode. |

Something out of warranty and they STILL won't part with a schematic? I wonder why?
No, on second thought I don't care. Not a good policy.

There are a number of reasons why an amplifier could shut down. Not necessarily a bad capacitor(s). Until it is tested on the bench with schematics on hand, you are just guessing. These amplifiers have rather involved protection circuits. Have we done the basics? Trouble shooting to see if there is an outside influence causing the shutdown.
Details on the original post rather few on that area.

For Example?
Unplug and let it sit for a while.
Disconnect speakers and inputs.
Will it now start up?
If YES, reconnect inputs.
Still OK?
Connect speakers one-at-a-time until failure. Than do the 'swap' thing and confirm speaker wires thru additional swapping.
IMPORTANT:
Follow proper power down procedures when doing OR UnDoing connections. Those nasty 'zaps' can damage stuff.

IMPORTANT: Follow proper power down procedures when doing OR UnDoing connections. Those nasty 'zaps' can damage stuff. ... Which would be...? (As a PSA for the uninformed among us) I'm thinking, POWER AMP ON - Last POWER AMP OFF - First I assume my triggered connections do that, but if one isn't using triggers, is there a specific sequence for everything else? |

SOME power conditioners have time delay to various outlets. They'll 'wait' a few seconds (assignable) B4 turning on.
My note about power down procedure was for the troubleshooting of the system. DONOT simply start unplugging stuff while it is still powered or even plugged in.
