Hi guys

I have a question regarding the Dolby surround upmixer.

Currently I have a 9.1.6 setup.

Previous I had a 7.1.2 setup running off a Yamaha aventage RX-A2050

With the Yamaha when I played games on my switch (Pokemon sword for example) or any game on the Xbox one/watched any movie that wasn't in atmos (5.1 or 7.1 content) It would be mixed into all channels and sounded great.

Since Getting the XMC 2 I've noticed that the DSU will only play sound from

Front L/R
Centre
Top Front
Top Rear

It won't play any sound from
Top Middle
Side surrounds
Rear surrounds
Front wides

Now I am aware the DSU doesn't support front wides but I'm unsure why the same content on the XMC that I played on the Yamaha has stopped playing out of the Surrounds and Rears (not sure if Top middle is ever used as I didn't have those before)

Is there an issue with the processing on the XMC that anyone is aware of? Running FW 1.9.

I should mention any Dolby Atmos (TrueHD or DD+) content appears to work fine on all channels. 

I also noticed when Using DSU on Tidal the XMC doesn't use the Sub (set to LFE with Fronts set to Full range) whereas with the same config on the Yamaha the sub was used in Tidal music on Surround mode (direct 2 channel only use L/R as they should).

With different specific circumstances, I asked a similar question a while back and got no answer.  Interesting that you're seeing some issues.  I'm on 1.9, and my system is 7.1.4.   Here is what I observe:

-   2-channel source will always upmix to all channels with both DDSurround and DTSNeural:X.   This includes HDMI or USB DAC playing from the PC, as well as 2-channel CD/SACD.  Also 2-channel music or video from AppleTV 4K.

-  5.1 video sources on AppleTV 4K will upmix to DDSurround.   They do not upmix to DTS due to the rules that Dolby/DTS impose on upmixing multichannel only from their sources.

-  Multichannel music from SACD (OPPO 205) will upmix to DDSurround or DTS.  Note that I have the OPPO convert DSD to PCM.

-  Multichannel music from network drive sent to OPPO 205 over network (JRiver Media Center Send To>Play (OPPO205) will NOT upmix to DDSurround or DTS.

-  Multichannel (5.0/5.1 PCM) music over HDMI from the PC only plays 5.0 or 5.1.  It does NOT upmix to the rears or heights with either DDSurround or DTS.

I thought there were some DSU regulations that Emotiva had to meet.

Keith how much control does Emotiva have on how things are processed when the input runs thru the “decoders” on the DSP?

Same problem with the RMC-1L and an Auralic Aries streamer. After every standby and wake up of the RMC, I have to either reboot the Auralic or disconnect and reconnect the USB cable. Sometimes flipping the USB mode in the menus from UAC1<>2 also fixes it.

You guys better go back to a XMC-1, mine is connected to my Mac Mini via USB and zero issues, I'm glad I'm 1080p and non Atmos as it seems I can keep my sanity in check better

I'm with you. Quite happy with my XMC-1 in a 5.1 system and a 1080p Panasonic plasma.

It’s always great when you are happy with what you have and don’t need to upgrade. Saves a ton of money too.

Nothing wrong with that. But also nothing wrong with listening to 9.2.4.

Ok guys I’m thoroughly confused. I decided to finally take the time and put REW on my speakers and calibrate. Started with the sub which is connected to the minidsphd from center sub selected as mono. I want to get rid of the crossover so I can take a full measurement but no matter what I do it’s the same shape. I’ve got into bass level and set it to the min of 40 and max of 400. I then went into the center which is set as small and set it’s crossover to the max. Nothing I do will remove the crossover so I end up with a graph like this instead of a full range. What the heck am I doing wrong and why is this so difficult lol.




Edit: also I figure that the center sub should be configured for LFE according to the manual but I do not have that setting only mono or none.

You won't have the lfe option until you hook up other subs I don't think. At any rate, mono is likely correct for what you are doing.
Second, which channel are you measuring?
It looks like you are measuring a channel that is set to crossover at 60-80 hz. There could be room modes or timing/phase alignment issues are well causing that dip at the crossover point.
First, set your levels using REW to make sure all speakers being tested are at the same db.
Then, say... You are measuring the left channel, whatever you put as the crossover for the left channel is where this sub will start taping off. (Or just before)
If you are trying to measure the subs response past the crossover point for the left channel, then set the left channel's crossover to the highest number and measure up to 120hz or something. The only place I see this as valid would be for lfe content that will play out of the sub regardless of the frequency. Otherwise, you're only concerned about it around your highest crossover point.
You talk about a full range measurement though. You would only want that on your speakers.. Not your sub. If you want a full range measurement on your speakers, you're going to have to set that speaker to large for the measurement, then set it back after.

Thanks for the reply. I understand all of that what I’m trying to do is near field measurements of my pair of subs I built to compare them to the hornres response. On my marantz I would simply increase the LFE to 250hz and be done. Run hdmi 4 and I get the response to 250hz no problem which would be perfect for comparison and also for adding REW filters up to 120hz. Then change the LFE channel back to 120 so it has a natural roll off. I believe marantz used 12Db/octave. Now in order to take true sub measurements with the XMC2 I’m not seeing how this is possible. Let’s say I want the sub to play to 200hz flat or house curve doesn’t matter is there a way to accomplish this? Theoretically I should be able to raise the center crossover to the max (200hz) then set the bass level to max (400hz) and it should give me the measurement range I’m looking for but no matter what I change I end up with the same graph in REW. Does that make more sense?

Edit: I’ve also found that setting center to large allows the option for LFE on the center sub but still no change in REW measurements. Note the measurement is being taken about 2 inches from the mouth of the QW of the sub.

I think it does. Two recommendations.
1. Use 3rd party ASIO drivers in REW to have the ability to select all individuals channels to measure giving you the option of measuring the sub directly.
2. Set your left channel to full, swap your left channel output, from the processor, to feed your sub amp. Run measurement. You may need to adjust and distance settings or existing PEQ applied to your left channel. The easiest way to do this would be to use a different preset as not to jack with the other.
Make sense?

You may know this, but lfe is only going to play the lfe content... Which, you have none via REW. You'll need to use mono, or similar, if you are wanting to set the speakers to small. Unless I'm missing something here.
You don't have a good way to "engage" The mono sub directly from REW without the ASIO drivers or to manipulate the situation by using the left channel tying it to your minidsp.

I’ve got the ASIO drivers loaded. Just for clarity sake I’ve been using REW for subwoofers for a very long time as I design and build subwoofer regularly. These are a pair of the largest size devestators I build based on a buddies design. This was right before I painted

HDMI4 in the ASIO is LFE so swapping the input shouldn’t be needed as I’ve never done it previously for sure. Here is a measurement I’ve taken with the same subs on my marantz. Notice how the crossover is applied much later and doesn’t not drop starting at 60hz. This is using the same minidsp to LFE channel setup

Those look nice. Good work!
So, using the ASIO drivers isn't allowing you to target the center sub performing a full sweep? Or.. It is and it is still engaging a crossover.
If the latter, are you super positive you don't have a HPF or LPF inside minidsp? I'm pretty certain that the default configuration in minidsp applies these filters and you have to remove them all prior to starting your measurements. I guess I'm saying to be sure every single tab in the minidsp software is clear of anything that could cause this.

The mini dsp is set to be wide open. If I recall the filters are defaulted to 1000hz so if you forget to bypass them you would either get no sound or it would work just fine no in between but I could be remembering incorrectly. Either way yes all filters are bypassed

And yes I can select LFE or hdmi4 no problem but it is still applying a crossover. I’m not sure where it’s even getting it from since all crossovers are maxed just to test

As a thought... Are you positive that HDMI 4 is the sub output? If I remember correctly, you just get numbers with no real way to know which channel is which. The only thing that makes sense to me is that you are measuring a channel that is set to small, and that channel has a crossover set somewhere around 60hz. If you were measuring the output, in REW, that was specifically tied to the center sub, I wouldn't expect to see this crossover. It is odd for sure.

Yeah I’m positive hdmi4 is LFE but what’s even more odd is I’ve mess up my entire setup trying to figure this out lol. I’ve got every crossover for all speakers set to the max of 200hz just to test and same darn thing. Something clearly isn’t working properly in 1.9 I’m just curious if others can reproduce it

curious... Try changing your slope to 12db per octave and see if the sweep is different. The only place one can manipulate crossover is in a specific preset for a channel. Yes, there are other trims, but I don't know that they'd come into play like this. Second, even though they don't work, make sure there is no peq on the center sub. Third, as a sanity check, make sure you are actually using the preset you are changing.
Lastly, if I were doing what you are, and changing the slope to 12db caused no difference, I would be determined that it was something in the minidsp because not much else makes sense.

Hoping my xmc-2 arrives this week, if so I'll run REW and see if I can duplicate.  Thinking you are missing something in settings in either REW or the processor. Maybe, set a main speaker to largew, run a sweep and see what that does?

He's using ASIO drivers in REW which typically allows you to specify the sub channel which should let him do a full sweep. Otherwise, I agree.. Swap some cables and run a sweep that way. It just sucks because you ideally should be adjusting distance and all that. This is going to matter more though when integrating to the mains.
It does seem like some setting in REW or the minidsp logically.

As a thought... Are you positive that HDMI 4 is the sub output? If I remember correctly, you just get numbers with no real way to know which channel is which. The only thing that makes sense to me is that you are measuring a channel that is set to small, and that channel has a crossover set somewhere around 60hz. If you were measuring the output, in REW, that was specifically tied to the center sub, I wouldn't expect to see this crossover. It is odd for sure.

Yeah I’m positive hdmi4 is LFE but what’s even more odd is I’ve mess up my entire setup trying to figure this out lol. I’ve got every crossover for all speakers set to the max of 200hz just to test and same darn thing. Something clearly isn’t working properly in 1.9 I’m just curious if others can reproduce it

Do you have a top end cut off set in the minidsp? If I remember correctly, Emotiva only runs the LFE out to 150hz but I'm not certain of that.

Hoping my xmc-2 arrives this week, if so I'll run REW and see if I can duplicate.  Thinking you are missing something in settings in either REW or the processor. Maybe, set a main speaker to largew, run a sweep and see what that does?

Using my left and right sub for heights so I'll be running both subs off center and through a minidsp.  Hoping to use the mini strictly for time alignment and then see what Dirac will do with frequency response.
