Even if this subject may be important to fewer sophisticated users I think it is quite interesting nonetheless, also I believe that Emotiva is listening and that the XMC-1 is a product with a great potential that they will keep updating and improving if necessary instead of replacing it with a new model every year. Actually I don't know about the current XMC-1 but, as hinted by some forumers who would like indipendent delays and levels but a summed EQ, I think that the implementation in the product does allow a summed subwoofer to be implemented like that... however there is nothing we can do on our side to make that happen. I imagine that if desired Emotiva, now or in the future, may play the stimuli in both subs at once for both detected subwoofers, and then apply different gains and delays to the individual subs. Of course the gain and delay values from our tool should be disregarded in that case (this also should be possible for Emotiva to do) and also changing these values will need a recalibration. In any case I expect that the XMC-1 with Dirac Live will be a great performer and an innovative product... so let's see what the future will bring  Ciao, Flavio |

The full pink noise is only useful for those with a 1/1 RTA. Besides Markus who here has one?  Probably igorzep, sme, and urwi I agree 100%. My observations were really to show that Emotiva is gotten many of the small details right. I was poking around last night in the Dirac speaker preset, and I noticed that there's no option to configure level or distance. I assume this is because Dirac does it for you. At this point, I don't see any way for the workflow to get two subs in a mono configuration to work properly. |

I don't post much on hear but have been enjoying my XMC-1 for a little bit and so far its great unit. The issue above presented itself to me and the fix was to setup your subwoofer's up using the stereo sub option and from there you can setup the levels, distance etc on both the right and left sub channels and then switch back too dual mono. I have done that as a work around, but not 100% sure it is working and accurate. Plus shouldn't dual mono be able to sum the two subwoofers as one output? With one combined test tone to set the level? Shouldn't there be some instructions on setup for Dual mono subs? |

Hi Flavio, Can you help me understand how this would work? If the gain and delay values from Dirac are ignored (i.e., if Emotiva implements a way for us to manually configure this before Dirac process the subs as 1 output), would you still have the ability to correct beyond what one can do in a PEQ? I'm just trying to understand how this might eventually work. |

Under Markus' guidance, I ran a few tests on the test tones being put out by the XMC-1. The only oddity uncovered is that the subwoofer test tone is ~9dB lower than the main channel tone when all trims, filters and distances are set to 0. Markus also pointed out that at this price point, it would be nice to have a user selectable LPF, and full bandwidth pink noise for use with a 1/1 RTA. The full pink noise is only useful for those with a 1/1 RTA. Besides Markus who here has one? It would be a .001 percent used feature. The other issues need to be fixed first. Users are starting to notice. emotivalounge.proboards.com/thread/38492/dual-mono-subwoofer-bugs?page=1&scrollTo=665519I can only assume at this point that no beta testers had dual subs to test this .2 processor. At least it this will help them put out a better product. Why would it only be useful for 1/1 RTA and not also 1/3 RTA and/or FFT variations? |

Agreed, there are so many XMC-1 threads they're hard to follow, they are more likely to get attention (and proper comment) if existing threads are used. |

As suggested by a few of the members, the "dual mono subwoofer" thread has been merged into this one.

It would be useful for all kinds of steady state frequency response measurements. Not sure why people argue against features that would make the XMC-1 a better product. The full pink noise is only useful for those with a 1/1 RTA. Besides Markus who here has one? It would be a .001 percent used feature. The other issues need to be fixed first.

It isn't that I'm against it it is that there are other more pressing issues to address.
I guess I see it as an order of importance.
But I'm not against it if it comes out in a future firmware release.
I believe that this capability is already built in but just not enabled.

There is no way to measure that it is working, because the test tones when in Dual Mono Subwoofer don't work properly. I have done what you have done, but I can only Hope that it is working properly. Shouldn't the Dual Mono Subwoofer have a combined output test tone to set the level? Most if not all Emotiva competitors have this option, which is logical. |

Yes the settings I used in stereo mode during setup appear to be working, and I did not touch the EQ on either subwoofer.

One of my subs is set @-2.0db and the other is @+1.0db, with my subs I would notice if one is playing significantly louder than the other. I haven't touched the gains on either subwoofer since I set up my XMC-1. I did switch to dual mono subwoofer mode after I noticed that in stereo mode, both subwoofers were not playing sound during my listening. The subs I have hit pretty well when I get everything going.

The other observation I am not sure if anyone else has encountered is during ALL Channel Stereo. With the way I have the XMC-1 configured the overall volume on my 7 speakers seems to dip a ton and the subs keep pounding away at normal volume. It becomes super bass heavy during music playback.

That's been posted in the 'bugs' thread. Okay cool, I kinda figured everyone else was running into this as well. When I saw it as a sound mode, I thought, man I gotta see what this sounds like. (I was never able to get all channel stereo on my old UMC-1 to work for music.) |

me... Pink noise is something I use all the time. I would have assumed it was built in.

/b There's a pink noise test tone built in. We're talking about full bandwidth vs. Limited bandwidth. |
