I just received and installed my pair of xpa1s. The problem is when input them into standby there is a high pitch whine coming from one of them. Flip main power goes away in standby its whining, on it goes away. Any ideas gang?

Bummer, mrranting.
Would call Emotiva on Monday and talk with their technical guy for the XPA-1 Have talked with Grayson in the past and he has been helpful.
You have 2 issues in dealing with the problem. They are uber-heavy to transport and would be a pain to send back and they have sold out the line so cannot, probably, provide a replacement.
Good luck and let us know.
Does the amp work fine when it is running?

Unfortunately sounds like the standby coil (if a relay), transformer, and/or other part(s) of the circuit is(are) defective... Without a schematic it is difficult to guess. You might be able to help them troubleshoot by listening closely around the top to see if you can better localize the sound source inside the unit.

Do they not test out the amps before they ship them? Doesn't look like it. Check the serial numbers on the back and see if they are close. If so, then return/refund the units as it will be a matter of time before the other one starts to act up. They could have been from a bad batch and it would have been many units later before the parts bins were refreshed. Just my $.02. |

I don't think Ryan has an issue getting a refund, he bought them new and just received them on Tuesday, he has the thirty day in home trial to return them. More less trying to figure out what would be involved in the fix.

All products are fully tested and burned in before packaging and shipping, but things can happen... It could be one of dozens of issues causing this noise but a "bad batch" of something or another thing is not one of them. I'm not sure what exactly the noise issue is, so I'm not going to try and guess. We'll send an advance replacement to you tomorrow. Please give us a call and ask for Cathy or Janna. They will get you taken care of ASAP. My apologies for the inconvenience. Cheers, Dan |

Dan:
This is impressive CS; congrats to Emotiva for this kind of professionalism.
My set arrived yesterday and I am delighted with the XPA-1s. They are one fine amplifier and I personally would love to be able to buy more in the future.
All best,
Craig

Do you have it plugged in to a power conditioner? That could be the reason. The XPA-1 L amps had problems with this.

More less trying to figure out what would be involved in the fix. Is subtle. Sounds similar to an old tv with no signal to it. The weird part is it's only in standby and appears to go away after about 30 mins or so. I thought maybe some kinda interference but the other one was stone cold silent. Dan has assured me that the problem will be taken care of. |

The amp is stone cold silent when on and performs flawlessly as far as I can tell. And they've been on so much I had noticed it till I sh** them down and mowed the lawn. I think I heard it on day one but thought my ears were just "ringing" a little from the initial test drive. |

Generally Speaking, what most people think of as QC (endless checking of product) is IMO, a near-complete waste of time. The leverage, from a profit / quality standpoint lies with having proper people, completely trained, doing the right thing per SPECIFICATION (build spec and procedures) with proper equipment to do the job correctly THE FIRST TIME. Rework and Warranty stuff is $$$ and ultimately costs EVERYONE more $$$. This is 'in general' and when going into detail, much can be done to ensure doing it right the first time and with high reliability and in a reasonable amount of time. Cost Effective. |

odd that it disappears after ~30mins.

I had a previous issue with an Emotiva product purchased new also. I must say they immediately shipped me a new product in exchange. Great customer service. You can be assured they will make care of you.

Just an update. So if I turn them on and play for about 5 mins the whine is there in standby and doesn't stop for several hours, my perception of time might have been altered a bit when I said 30mins. I know i heard it last night when i shut them down for bed. When I woke up and came into the room quiet.
Now if I power them on for just say 30 seconds and shut them off nothing. It's only there once they've warmed up.
Day 6, bow the noise only gets quieter in standby never really goes away. Dan Laufman (who I just found out owns Emotiva) has made every effort to correct the issue of which I'm expecting a phone call soon on. I purchased dozens of components over the years, and never once had the owner of the company personally assure me the issue would be resolved. This is customer service the likes of which other manufactures should take note of. Emotiva will be a corner stone in my household for years to come because of this treatment. Thank you, and most of all the satisfaction of your customers could not be more apparent. Good form.

Did you find a solution to this problem? I have one amp doing this exact same thing and the other is 100% quite when they are in standby.
