If this was in the manual, I missed it. I use a miniDSP AVR DL between the Blu-ray player and and the MC-700 (it gives me Dirac room equalization). The miniDSP requires me to set the Blu-ray player to output LPCM, which means the Blu-ray player does the surround sound decoding, not the MC-700. My only mode choices in the MC-700 with LCPM are Stereo, All Stereo and Direct. The MC-700 chose All Stereo as the default mode and despite its name, it does seem to output 5.1 or 7.1, depending on what format is on the disc. I fooled around with Direct while watching a movie tonight and it seem to change the sound, but I wasn't sure exactly what is was doing differently; it kind of sounded like it might be bypassing the crossovers I set in the MC-700 to divide the signal between the main speakers and the subwoofer.
Does anyone know what the MC-700 does with the signal in Direct mode and how that differs from All Stereo mode?
This might be worth a mention in the next version of the MC-700 manual.
Thanks.

Based upon the name, I assume the direct mode doesnt do anything to the signal. Interesting that "all stereo" converts playback to 5.1 or 3.1.
I need to check that out.

If it's anything like other Emotiva processors:
1) All Stereo - routes all main left channel signal to ALL left surround speakers, routes all main right channel signal to ALL right surround speakers, center channel is mixed left and right main signals, most other processing is available i.e. bass management, tone controls, etc.
2) Direct - Routes all PCM output to the correct respective speaker, avoids most processing EXCEPT bass management
The XMC-1 manual gives a detailed breakdown of each mode.

Your MiniDSP uses an HDMI connection to the MC if I'm not mistaken. I would think you should be able to select a surround mode in that case as you can with the XMC or UMC before it. Try calling Emotiva. |

Rvsixer,
Thanks for the clarification.

What he said, and to add: 3) Stereo - routes to main left/right + sub out, only. |

I looked into this a while ago when trying to setup my old PS3 for 1080 bluray playback. All Stereo is the proper mode for multichannel PCM surround. If it receives a stereo input, All Stereo will do as stated above where it sends all left channel to all the left speakers and all the right channel to all of the right speakers. However, if it receives 5.1 or 7.1 surround PCM, All Stereo will properly apply bass management and EQ and send each signal to its respective speaker. The difference with Direct mode is that it does not apply EQ (and bass management maybe, not sure). There was a discussion on AVSForum about this, and I thought this diagram was helpful: www.avsforum.com/forum/90-receivers-amps-processors/1491348-official-emotiva-umc-200-thread-4.html#post24254494 |

No Bass Management in Direct mode.

So the MC-700 is more like a UMC than an XMC in that All Stereo IS the surround mode. Unlike the XMC in which All Stereo always results in only two channels being played across all speakers. In that case All Stereo mode would be the correct surround mode for multi channel PCM.

Out of curiosity, what is the proper mode for multichannel PCM with EQ and bass management in the XMC1?

Thanks for the responses. Subjectively, it did not sound like any bass management was being used in Direct Mode, and it appears that is the case. I'm glad I wasn't watching an action flick with a lot of really low bass when I was fooling around with the mode switch or I might be replacing some woofers in my relatively small main speakers. Emotiva might want to consider including something like the diagram in the AVS thread in the next version of the MC-700 manual since the names of the modes do not fully describe what they do. No Bass Management in Direct mode. |

Out of curiosity, what is the proper mode for multichannel PCM with EQ and bass management in the XMC1? Which ever mode sounds best to your ears; completely a preference choice. All of the modes will give you bass management, except Direct, so some like multi-stereo, some like PLIIx (or whatever it's called), some like Stereo, etc... |

No Bass Management in Direct mode. Strange they would make the MC-700 direct mode different than the UMC-200/XMC-1, etc. From XMC-1 manual: Direct Mode provides a relatively pure listening experience, and eliminates most processing, but still retains bass management.: • Bass management IS available and the subwoofer IS active. • All signals receive bass management - but no other processing. • If an LFE signal is present, and one or two subwoofers are also present, the LFE content will be routed to the subs along with low-frequency content from the main channels (as determined by the bass management settings). |

Hmmm, my UMC-1 Direct had no bass management, and my XMC is boxed up so I can't confirm, but I can test this evening the MC-700's direct. You might be right. Normally, though, that's the difference between Direct and Stereo.

MC-700 Direct is definitely without base management. Just tried it out.

I wish it was possible to use PLIIx with PCM in the MC-700 to synthesize the rear channel signals with 5.1 sources, but it does not seem configured to permit that. I wonder if this could be added in a firmware update? Out of curiosity, what is the proper mode for multichannel PCM with EQ and bass management in the XMC1? Which ever mode sounds best to your ears; completely a preference choice. All of the modes will give you bass management, except Direct, so some like multi-stereo, some like PLIIx (or whatever it's called), some like Stereo, etc... |

I get what you're saying, but I think you misunderstood my question. I want to know what the mode is called in the XMC that does the same thing as All Stereo in the MC700. Which XMC mode is multichannel PCM surround 5.1 or 7.1 with bass management and EQ applied? Maybe it's just called MultiPCM or something. I just think it's weird that you have to choose All Stereo for that. |

I don't have mine set up but thought it also had one called "All Stereo", but Geebo probably has his at hand and is right with "Surround". |

I don't have mine set up but thought it also had one called "All Stereo", but Geebo probably has his at hand and is right with "Surround". It does in fact have an All Stereo Mode but it's not like the one on the UMC-1. It's what some call Party Mode. All Stereo on the XMC mixes any content to two channel and directs resulting left signals to left speakers and ditto for the right. The center channel get a mix of the left and right signals.
• Surround sound digital signals are decoded, mixed down to stereo, and converted to analog
(the Center Channel and LFE signals, if present, are mixed into the stereo output).
• After all processing is completed, the left signal is routed to ALL left side speakers and the
right signal is routed to ALL right side speakers; and the center channel speaker receives a
mix of left and right. .
• If an LFE signal is present, and one or two subwoofers are also present, the LFE content will be
routed to the subs along with low-frequency content from the main channels (as determined
by the bass management settings). |
