Need some help with my UMC-1. Been trying to figure this issue out for two weekends and still no luck. Tried every setting/combination with no luck. My setup: XP2: Drive the main speakers XP5: Drive the center, side and back speakers DVD: Sony S360 UMC-1 Input Setting: HDMI Audio/Video When I power up with just the XP2, everything works fine. When I power up with both XP2 and XP5, it then starts to drop video/audio signal every 5-10 seconds with message "No Audio" displaying on UMC. Then after 5 seconds or so, would then work fine for maybe 10 seconds...then screen goes blank and no audio....then back back on and off. When I shut off the XP5 and just leaving XP2 on only, the problem stops. So I have narrowed down to XP5 causing this but not sure exactly why that is. With my old Carver C1000A preamp, it works fine. Does anyone out there with this setup and encountering this issue. Could be an issue with UMC but want to check with you folks to be sure. Any help or suggestion would be apppreciated  |

Any help or suggestion would be apppreciated I have noticed one specific thing with the UMC-1. It does not seem to like voltage fluctuations, especially if it drops below 112 volts. When the voltage drops below that point, it can have drop outs and lock up. Is your XPA-5, 2 and UMC-1 all on the same 15/20A circuitbreaker? |

Wow, very interesting. Have you reported this to Emotiva and/or added it to the database? This could explain a lot of random behavior and bugs!

No issue with my UMC-1 and XPA-2 & XPA-5. They're all running on the same 20A circuit. Have you tried just powering on the the XPA-5 and not the XPA-2? That would rule out the XPA-5 itself being an issue, and I think ntrain42 is on the right path.
Do you also have the amps plugged into a power conditioner/surge protector? If so, try also connecting the power directly to the outlets.

ntrain
If the umc was correctly tested for the CE mark that it carries, It MUST work from 90 - 240VAC 50/60 Hz. (switchable to ranges about the 110 and 220 VAC is acceptable). The unit must also pass voltage dips and interrupts that are far worse than you are mentioning.
I certainly hope that the unit has passed CE certification. IMHO that certification carries a LOT of weight.

A/V drop outs on DTS and DTS M only; I can't explain why

I am too having similar issues but am told that when the new firmware upgrade comes that it should resolve the conflicts. Another oddity is that in Dish mode both my 5 and 2 apms all light up well while using the trigger, however when I toggle over to say my OPPO only the pre pro goes on and the 2 and 5 amps turn off. I assume this has to do with the firmware update that will soon arrive and everything will fall into place?

jtm.I presume you have the trigger/s engaged on the oppo input?

If you have any unused inputs between the Oppo input and your other inputs that are setup as not visible it will trigger your amps off. If the inputs between the Oppo and the others are visible thats fine (if the amp triggers are on) you would just have to toggle past them. The way to get around this is to have all your inputs together with no non visible inputs between active ones. I talked to Emotiva about this and they are aware of this issue. Bill |

Thx Moe for the info. I tried find the trigger settings to ensure that I had applied it properly to my Oppo but can't even get my tv to give me a picture; all my products or accessories seem to be mixed up. So my latest move was to unplug my TV and I also did a fresh total set up or at least it is ready to do it over again. I also unplugged my trggers. So sometime later I intend to wrestle with this somemore. I hope my TV is not damaged. I really need someone to talk to whose had these problems. I have perused many feedbacks re the UMC-1 and trying to hold on while the firmware is being massaged. Anyone who wants to talk about possibilities or have any suggestions as to at least me being able to get unfragmented should while we await the new firmware, I would appreciate it. You may give a call to my cell at 541-497-3457. Maybe we could go step by step. Should anyone have the time to do so. I don't want to be impatient or call the kind folks at Emo while they are trying to work things out.

A/V drop outs on DTS and DTS M only; I can't explain why I believe the new anthems had problems with those 2 also. A firmware fix was released to solve the problem. |

I had that same issue at one point and it turned out to be a loose HDMI cable in the back of my TV. I made sure all the HDMI cables were tight and haven't had the issue since.

I have noticed lately that the audio drops out when a movie with DTS-MA starts and won't come back unless I change the inputs.

I hope your right, but it seems like when the unit locks up Im right around 110 volts..........Ive been watching this carefully, when the voltage is over 115, it never seems to happen..............I cant say this is the reason for sure, but it always seems to happen when the voltage is lower than norm........... |

Im not sure if this is the same problem from above, but sometimes my umc does not output any sound, like it goes mute yet The umc does not show no audio on the display, it just stops sending audio..THis only happens when Im swithing from channel to channel occasionally. All I have to do to fix it though, is move input up then back to sat.

Ntrain, I have noticed this as well. Our recent Noreaster' in the Northeast has given me the opportunity to observe several voltage fluctuations over the weekend. It definitely had an effect on the UMC-1 and audio dropouts. A reboot seems to solve this. |

If this low voltage issue does turn out to be factual, it would certainly explain why the user experience with the UMC-1 varies so much from user to user. I have a steady 122VAC at the wall socket my UMC-1 is connected to and have not experienced a single random lockup/audio drop out described by some of the other users. I am wondering how many people actually run thier UMC-1 on a power conditioner?

I am wondering how many people actually run thier UMC-1 on a power conditioner?I run all my gear from the APC power conditioner which regulates the fluctuating input voltage (anywhere from 110V-131V) and outputs a constant 120V. I have not had any lockup/audio dropout issues with the UMC-1. |
