exactly...why even have a UMC with this scenario?? The UMC is doing nothing but passing the signal through to your amp. Moodyman The UMC-1 definitely has a hole in how it currently performs with MC-PCM, but you are exaggerating the problem when you say the UMC-1 does "does nothing but passing the signal throught to your amp." Below is a segment of Lonnie's response to an E-mail message he sent to mick16: "At this time you do have other options where the most likely scenario is to use PLIIx which is an overlay of the MC-PCM code and does apply the EQs. In direct mode now EQs, are disabled, but bass management and delays are still active. We are looking into applying the EQs to the MC-PCM code to see what would be involved in it." The problem is no where near as bad as you posted. Your frustration is understandable, but as you can see from Lonnie's E-mail this is a short-lived problem; and in direct mode you currently do have bass management and active delays. Emotiva is also examining the options for adding EQ processing to the MC-PCM signal. Things are looking up. I stand corrected. |

When you guys say bass management isn't working. What feature are you calling bass management?
Obviously we're not talking about the lower frequency EQ settings because that's just part of the EQ.
Are we talking about the cross-over settings? I tested those once I read of these issues with LPCM because I was worried I might damage my speakers, but as far as my ears could tell it was definitely applying the low and high pass filters I set.
What else are we talking about? Maybe enhanced bass? I wouldn't know if that works because my speakers aren't meant to go full range so I can't use that feature. Maybe we're just talking about the sub's dB setting?

I was talking more about how it rolls the bass depending the speaker crossover setting. To be 100% honest, I don't know if its correct or not, but the bass and surrounds just don't sound correct when I'm listening to blu-rays via MC-PCM with the PS3 fat.
Maybe its the lack of EQ functions, I don't know. But to their credit, Emotiva seems committed to fix the problems, so I'll give them a shot to see if they can get it corrected.

This is a setting where you can turn the LFE down up to -10db to match other audio sources. In my setup, Dolby Digital is 10db hotter than DTS, so I have all of my Dolby Digital LFE levels at -10db. But when watching a Blu-ray from my PS 3, (in direct), this setting is ignored. |

Last night I turned on PLIIX while I was watching a blu-ray and thought it sounded OK despite my prior experience with it sounding weird. Maybe it depends on the blu-ray? But tonight I was playing Bioshock on my PS3 and the UMC-1 says 'Direct 48khz MultiPCM' and lists out all 7.1 channels. But despite this I'm unable to select PLIIX or any other mode except stereo. When I leave it in direct I get good sound from all channels... just missing the EQ. No, your crossover settings are still active. I have tested this myself. What we are talking about is the LFE level. This is a setting where you can turn the LFE down up to -10db to match other audio sources. In my setup, Dolby Digital is 10db hotter than DTS, so I have all of my Dolby Digital LFE levels at -10db. But when watching a Blu-ray from my PS 3, (in direct), this setting is ignored. Well I know some past discussion has talked about how if you set, say, your L/R channels to not play anything under 80Hz (for example), that most processors will take that 80Hz and divert it to your sub. I don't think we ever got clarification/confirmation that the UMC does that, but could this also be a bass management feature that goes missing when in direct mode? Or will that still be functional since the low and high pass filters are still otherwise functional? |

Bumping this post hoping someone can tell me if there is a mode for processing M. Ch. PCM and have the EQ used after this new firmware? I didn't see anything in the new firmware changelist looking like it would address this.

I didn't see anything in the new firmware changelist looking like it would address this. Yeah sounds to me like they've done nothing to fix this in the current firmware. It would be nice if they'd at least pop into this thread and tell us if it's in the works. I mean a few weeks ago Lonnie seemed to be under the impression that the UMC-1 already had a native mode available for PCM. When he found out it didn't everything got quiet... I haven't heard a peep out of anyone from Emo about this issue since then. |

Love to hear on this issue as well as many of us have older BDs with uncompressed mixes.
If DD PLIIx just adds the EQs and does not do any other processing, I'm fine with just leaving that mode on when i watch uncompressed mixes. Further clarification on this issue is much appreciated.

I sent an email to Lonnie a few days ago. Here was my question:
"1st-I have a PS3 (older 80GB model not able to bitstream advanced codecs but will send multichannel PCM) conected via HDMI to my UMC-1. When I pass Multichannel PCM to the UMC-1, I am only able to select between DIRECT and STEREO modes. The DIRECT mode, if I understand correctly, bypasses all Emo-Q tweaks I have set-up and STEREO goes back to 2 channel only. I would like to input multichannel PCM to the UMC-1 AND keep the Emo-Q Settings and bass management intact. Is this possible now or in the future?"
Lonnie responded on 5/5/2010 with this:
"In regards to the MC-PCM, we are working on new code to allow EQs to be applied to this input stream and hope to have it out very soon. The bass management and crossovers will remain intact."
I was hoping to see it listed in Big Dan's latest post...so we'll see next week if it made it into the new firmware.
