Well, I woke up this morning to watch the news before going to work and turned on my UMC which triggers my xpa5 and a strange startup noise came from the umc.
The noise sounded like when you would turn on an old crt monitor. Like a "PENGGgggg"..
So i turned it off, waited a little while and turned it on again and same noise but my light became amber and loading....showed up.
So I pressef "off" on the remote and the amber light went to blue and turned the unit on and it worked..So I left it on and I will see what happens when I get back home.
Just to let you know, I hadnt watched any tv/ or had my umc1 for a few days..and then all of the sudden this happens.

That sound on monitors was the degaussing of the screen...

Considering the power requirement of the umc I would not think it's the cord,but it may be woth switching and see.What is the UMC plugged into?

Maybe it had to degauss itself? Sorry, I know, it's not funny.  |

i have had that same sound with one of my receivers....but i have had no problems with the receiver itself.....its almost like a mass power surge on turn on that vibrates through the chassis....

Ok, I'm actually becoming REALLY concerned about this. Why is the UMC-1 acting so funny with any sort of power conditioner? It makes no sense to have to bypass something that's supposed to protect and improve our home theater equipment.

No kidding, I'm wondering if the weird power up/down issue I have occationally is because its plugged into my APC H15.  One would think that the power conditioner would be more stable.  |

Maybe the power strip is not giving it the spike it needs on boot up?

For an audio/visual expert you should know that some device do not play nice with others. If it can function by itself then so be it. No complains. Do not make it a monster when it is not. Move on and complain about something else.

Move on and complain about something else. Dude, I'm really sorry. Somewhere in one of my signatures I must have accidentally put the wrong information. I'm not an A/V expert. I don't recall claiming to be one. I'm going to have to yield to your greater knowledge on this one, and probably all other things A/V. I thank you for your input, like I have thanked many others on many other threads. I also don't happen to be complaining, though, I'm again, very sorry that you misconstrued my words to think that I was. I am merely expressing my concern over the fact that several people with different power conditioning devices have reported some sort of anomalies with their UMC-1. Perhaps you could lend further insight into this? What sort of incompatibilities are you aware of from other manufacturers that cause this sort of problem? Is it a specific type of device, e.g. isolated to Pre/Pro's, or can it happen with anything? Are there specific power conditioning manufacturers, that in your expert experience, you have seen have greater incompatibilities than others? I would really like to learn from your expert experience so that I do not have the same problems several other forum members are reporting. |

I have had issues with other components when the strip (Monster) was unable to adjust to the power needs fast enough. Got a conditioner with programmed start delays and everything is better

That's interesting because I've had mine plugged into my APC-H15 (along with all of the components except the sub.. which is too far away). I've had zero problems with my UMC-1. OK, there was a time when I had accidentally powered on zone 2 and wondered why the UMC wouldn't power off... but that was it. The APC-H15 is supposed to provide a constant voltage but a power on spike when multiple components are turned on might be the cause. Have you tried plugging in some of the units (e.g. amps) into the delayed outlets? |

I really don't think that it (APC) is the cause, can't really see why.
Yeah my issues have been discussed here before.
Power Down issue. Very rarely the UMC doesn't fully shut down. It hangs with nothing on the display, the "e" light turns amber, but the other buttons are still blue and the amp is still on. Can get it to work again by holding the "front" powerbutton a few seconds for a power cycle.
Power Up issue. Really not a big deal (hell I'm not even sure its a problem), but every once in a while (say every 5th power on cycle) the "Loading..." screen comes up then about 3/4 through the process the "e" button turns amber again and the display goes blank, for a couple seconds, then goes back to "Loading..." and the amp kicks on and everything is fine.
Really more of annoyances rather than problems, unless this will lead to a bigger issue.
