Are you running EmoQ, manual adjustment, or just simply connected everything and used the system? The results from each of these can vary.
Loading the firmware in itself will not have anything to do with this issue.

If you are having issues using EmoQ then I would pick up an SPL meter or download an app that you can use to manually calibrate/level match your speakers with. If you still aren't happy, you can increase the center channel volume until you are satisfied.
I should also ask how your components are connected to the UMC-1?

If you still aren't happy, you can increase the center channel volume until you are satisfied. I should also ask how your components are connected to the UMC-1? Just to take the speaker and wire out of the equation could you connect one of the front speakers and its wire to the center channel of the amp? Another thing to try would be to swap center interconnect from the UMC to the amp. |

Even if i swap my centre to any other channel u hear very low sound from whoever speaker connectec to centre channel pre out of umc 1 ,my xpa 5 is ok when i connect y centre speaker to other channel u can hear sound fine from it no problem, i mustsay there is something wrong with the hardware of centre channel interconnect of umc 1,i even raise the volume of centre channel to + 10db and when u play a movie u still hear very low sound

If they are not level matched, all the speakers will always sound different. I do agree that it is strange you have the same issue with even a 10db boost? Do you notice any change when you increase the level? The next option I would look at is connecting the center channel pre-out on the UMC-1 to another channel on the amp and see if the problem continues. If it does, it would point to the UMC-1. If not, this would point to a potential faulty channel in the amp. |

My all other channels are perfectly matched, when i increase the db level of centre channel i can hear a disorted sound and yes when i connect umc 1 centre channel pre out to any other channel u can hear very very low sound like if i connect it to front right speaker u can hear very low sound from front right speaker and if i connect it to front left speaker same thing happens, same problem with surrounds too
I'm 100% sure its umc 1 centre channel pre out fault

I have seen this many times - i do a lot of repairs, and emo items often come my way as a the go to guy for everything emo here in singapore.
If you are brave...or have a friend with electronics experience, then you need to replug the thin white ribbon cables that link the top and bottom boards inside the umc-1. This normally solved the issue in most units that i have seen with levels down in one channel.
If you need images etc i can try and find online but i dont really feel like taking my unit apart. You can pm me for easier contact details.
The ones you need to work on are the ones on the volume control side at the rear between the top input board and the output boards.

The cable carries all the channels in the one cable. If you want to send to me in singapore maybe cheaper but i would try this first. Worst case they will send you a new input and or output board that could also solve the problem but try the cable first. It is not worth your while to rma as the shipping cost will be too much.

Its late for me here in singapore. Opening up the cover in your situation should not be an issue...i do 99% of the replacement parts swaps here in singapore, but if you want to wait for a reply from emo to go ahead to check it its just a formality i guess. Maybe look for Joe in support or email Lonnie even. The guys there know me pretty well by now.
Ill look for a better image of what i am describing tomorrow if i get some time.

No soldering...you are looking for a cable that runs from the top boards where the 7.1 inputs are to the board below where the 7.1 outputs are. It will look like this but not as wide. en.wikipedia.org/wiki/Flexible_flat_cable As you have the unit in front of you and facing you its the right most side at the rear. Im off to sleep now...can pm me with your email and maybe i can help remotely tomorrow |

Read the wiki entry...plugging and unplugging is delicate but not beyond the scope of most people if they are careful. Try just the top connector first as that the easiest to get at...maybe that will be the one. Hold both sides between your fingers on the flat of the cable and pull up gently. Then push back down the same way...there is a stiffener at the ends of the cable to make this easier.
You might take it to a repair shop that does lcd screens or even iPhones and tablets as they will have encountered these connectors and cables before, but testing the results there will be harder
