I tried to use Dolby Volume very late at night when watching movies and it just didn't sound right to me. Ended up just using a lower volume! The current implementation in my unit is just plain wrong. Guess we'll find out if that's an error with the UMC-1 or Dolby Volume itself when the new firmware is available. So let's do what UMC-1 customers do best, wait  Best, Markus |

I wish there was a Dolby Volume button on the new remote. It would be better if you did not have to go into the menu and dig for it.
That being said, when I go to adjust the volume, as soon as the OSD comes up the sound changes(bass) before I have made a change in volume. Strange DV bug ?

Well crap...I went and looked at the diagram for the new remote and it does have a DV button. My bad, but good.

Of course it's possible there's bug in the DV processing. Strange though since the unit had to be sent to Dolby Labs for their blessing before they gave their stamp of approval and license. I guess the issue could have been introduced in the implementation post-pilot.

I've read through the article and I don't fully understand the question of using the modeler without the leveler. It doesn't really state in the article that they can work independently. It states the modeler should be on all the time and the leveler should be user selectable. While there are time I use dolby volume on my UMC, I don't think I would want it on all the time. Also there are three level options for dolby volume already available on the system.

"The volume leveling function is user selectable.". "On/off" comes to my mind first. 3 different presets of the compressor (that's what the leveler is) is nice to have but being able to switch it off is mandatory from an audiophile point of view.

Define works. I hit the button, the sound changes a bit, but I can't tell the difference between low, medium and high. When it is on, the only thing I really notice is that the bass is a lot louder. That's really about it. I hope it's bugged because if it isn't, it's pretty useless. same thing here can't tell and the bass get loud.. right now Dolby Volume is off |

Prior to purchasing the UMC-1 I had honed in on this part of the explanation of how Dolby Volume works:
"In addition, Dolby Volume modifies the audio depending on both content and playback level to replicate the way it would sound at the reference playback levels used in cinemas and studios*. The result is improved imaging, intelligibility, and audibility of the low-level content at normal home listening levels, which are typically considerably lower than professional reference levels."
I was hoping this would produce a much improved version of the old "night listening mode" where low level dialogue would be increased while the dynamics of the effects would be lowered so that you can listen at an overall lower volume setting comfortably while still achieving a pleasing overall surround experience. It appears that at least the way that it is implemented in the UMC-1 that by low-level they must be referring to increasing low frequency sound levels. When it is engaged in my setup the only thing I get is noticeably louder LFE not clearer dialogue or an overall sense of increased intelligibility of dialogue to effects levels.
I admit that I have no idea how it should sound with Dolby Volume engaged but at the moment I agree that in it's current form it produces no desirable effect for my purposes so I am just leaving it off for now. Not really a complaint but more of a disappointment from my end.

jdskycaster Dolby Volume does both: the leveler adjusts the dynamics using a compressor (see en.wikipedia.org/wiki/Dynamic_range_compression). The level of compression can be adjusted in 3 steps (low, medium, and high). The modeler is always active and EQs the signal according to the "curves of equal loudness". Basically it increases the volume of lower frequencies at lower levels. The problem is that we don't know at which volume a recording was mixed. This would require a reference mixing level which does not exist for music productions. But without having a reference level, correcting for the "curves of equal loudness" is simply impossible. The modeler will only work satisfactorily when there's a reference level like in movie mixes (85dB SPL). Best, Markus |

markus,
Thanks for the information. Do you think then that it is working properly in the UMC-1 with the current firmware? I primarily use it for movies and feel that it is not producing the effect you describe.
Thanks,
JD

Do you think then that it is working properly in the UMC-1 with the current firmware? If "properly" means "based on the equal-loudness contours of ISO 226:2003", then the answer is "No". Here's some more information on how these curves were obtained: www.nedo.go.jp/itd/grant-e/report/00pdf/is-01e.pdfBest, Markus |

After reading the status update details it appears I may get my wish with a midnight mode as part of this firmware release. That is excellent!!!! |

I'm really hoping that Dolby Volume got ironed out a bit. I'm a fan of the night-mode type listening technologies and always enjoyed that feature on my Yamaha receiver of old. |

Hi all,
DV has been corrected and is approved by Dolby. We did have an issue in DV in the first units and this is now corrected with the update.
NO one is bring asked to keep their unit if they do not want to. SOME clients have asked us to ship them their unit prior to the SW revision and we have accommodated them. We have also made it very clear to them that the unit would need to be updated, but they wanted them anyway because for most people, the issues were not deal breakers in the interim.
Again, I do apologize for the start up issues on this platform, but we have resolved all issues that we are aware of the unit is now working beautifully. Any owner may return his unit for a full refund right now if they wish to.
Please do not make it appear that we have a gun to your head. Everyone has a choice here. We are very happy that the vast majority of you are deciding to trust us and have kept your UMC-1's We believe you will be happy you did, we we truly appreciate your strong support.
Best to all,
Big Dan

Best to all, Big Dan Dan, I don't think anyone here is making it out as though they are stuck in a no-choice situation. I think mostly people are just discussing what is and isn't working, and what it sounds like we'll be getting out of the firmware update. I'm one of those that asked for my unit to ship with the old firmware, and I'm fine with that. I'm also excited to update to the new firmware. I think that most people have been pretty supportive lately, and as you said, if they aren't happy, they can always return the unit for a full refund. There has been discussion as to whether the UMC-1 shipped before it was ready, but I think the answer to that is in the fact that the vast majority of owners have kept their UMC-1's, despite some of the early-adopter growing pains. I think that most of us want to thank you for delivering the UMC-1 at such an incredible price and with such focus on sound and video quality. |

I'm just reading this thread to figure out how Dolby volume works on the UMC-1 and what the differences are between L-M-H. |

Same here. I'm just reading this thread to figure out how Dolby volume works on the UMC-1 and what the differences are between L-M-H. Me too. I'm excited for my UMC-1 to arrive this week. I'll be using it, new firmware or not, and I'll be upgrading as soon as the new f/w is available. I'm excited to see what sort of updates have been made to the Dolby Volume, as that's a feature I really value. |

Hey guys...I received my UMC-1 on Friday and got it set up over the weekend, but I don't see anywhere where I have any dolby volumne issues. Maybe I have the original firmware(without any updates), but I have no idea how to even check that...This may be a moot point with a new firmware due out tMonday or Tuesday, but I was just curious...

I'm not sure how it is supposed to sound but I can tell you that we have some crazy loud commercials and it has made a big difference with them. I just wish I could have it always on for tv and always off for movies. I need to figure out how to make it easier to switch.
