Keith,
I can hear what you are talking about, or at least it doesn’t sound like it should.

I hear a guitar.
What do you hear?
What do you think it should sound like?
Played one of the other copies of the sample again.
Might be a very small hum in the background but that could by my PC and its cheap speakers.
@Volounteer
If you listen when he plays his bass strings on his guitar it sounds a bit there is a phasing effect going on. You don’t hear it on his top strings, it is quite apparent when you really listen.
@Keith, Is that what you can hear but obviously in a better wav file?
That track as supplied does sound like there’s a phasing or chorus effect on the bottom end of the guitar?
The track as supplied sounds like there is a direct connection [guitar plugged in] AND a mic plugged in.

That’s kind of what I was hearing at least in my headphones…unless your putting a slight phase effect on the guitar and bass.
Here’s a thought and a routing error that can cause kind of that “effect”
First are you assigning/using any of the audio groups for the guitar and bass, not DCA groups but the audio groups?
If you are assigning the guitar and bass input to an audio group or groups and then assigning those groups to the main mix while at the same time those input channels are also assigned directly to the main mix your will get that slight “phaseyness” to the sound on the main mix out put.
You need to un-assign any input channels from the main mix that are assigned to a group that is assign to the main mix.
Are you applying any effects from the Qu Pac to those input channels?
If so any chance those effects are being routed even slightly back into themselves?
Any chance there is a mix routed back into it self?

Clearly your ears are more golden than mine.
What I hear I thought was intended FX and was not bad.
Phase in the lows and not in the highs sounds more like a frequency dependent delay from two channels coming back together.
@Volounteer,
As you have read, Mike C, xyz, Keith and myself can all hear the anomaly, you don’t have to have “Golden” hearing, but I will be honest, I do have very good hearing all the way up to 16k. 
@lee7
I used to hear way past that.
The IBM 2260 and 3270 terminals made a whine that drove me crazy.
Other folks said they could not hear them make that noise.
No idea what my hearing is now if it were to be tested.
Not sure exactly how BW of hearing relates to hearing phasing.
I did hear ‘something’ but to me it sounded intentional and very minimal.
For me not worth trying to ‘fix’.
I have to admit I do not understand how some folks are so fussy about getting that ‘exact’ sound.
Our MD goes to great lengths to get more BASS. I guarantee that nobody in the audience cares at all.
And other people are even much worse. I know he can hear the difference. I can hear the difference.
The real difference is that I don’t care about the difference. And neither does the congregation.
Like my uni prof once said: A difference that makes no difference is no difference.
And I tell others that perfection is not possible.
At some point in time you just have to give up and say its good enough and stop making changes or obsessing about it.
Our MD goes to great lengths to get more BASS.
More Bass as in the actual bass guitar or just more low end in general.
Can your system actually produce true low end frequencies as in shake the whole room, too many times people want more bass/real subwoofer kind of levels from a system that in no way can actually do it.
I’ve lost count on the number of mixes I’ve heard where the bass/low end overwhelms the entire rest of the mix.
Now back to the original problem in question.
More Bass in general but for certain performances even more so.
Yes, when he cranks the bass the desk at FOH vibrates.
To me it makes no difference. One good sound vs another good sound.
It must be awful to be such a picky perfectionist.
Some sounds will bother me. Even mp3 does most of the time, but I am not nearly as fussy as apparently most who deal with music.
And wonder how they can stand mp3 with all the other stuff they do to achieve ‘better’ sound.
What really bothers me is when my nephew produces a CD and the voice is under the music so you cant make out the words.
That seems to be a common problem especially with younger people. Why have lyrics if you cant understand them?
Looking forward to all y’all resolving the original problem.
@Volounteer
So could everyone else from a young age, but at 44 I think I am doing well to be able to still hear such high frequencies considering I am a pro musician and ad-hoc sound engineer, whereas lots of other people of a similar age group struggle to hear past 12/14k, some very much less.
I agree that perfection isn’t always possible if at all, and to be fair, it is very subjective as to what one person from the next would call perfection. But it is good to try and achieve the best sound possible with the equipment you have to work with. So in respect to Keith, he only wants the best sound for his live streaming, people will turn off if it sounds sub par, likewise, if the sound was great but his picture quality was very 1980s, people will turn it off.
so, again, the phasing sound is not a technical problem of the mixer itself
without confirmation from Keith it’s nonsense to speculate about it
it could be a problem of the guitar pickup as well…
@Lee7
I think I can hear higher freqs than that.
Will have to pull out my old test CDs and play them to check.
What is perfection anyway?
It is all 100.00000% completely subjective.
The only fair way to decide is by majority vote.
And most people just do not care about the various tweaks too many musicians prefer and believe is better.
If he wants the best for his audience then they should be telling him if they have problems not him guessing in advance.
Perhaps causing the problems himself by trying to achieve ‘perfection’ by adding things.
I agree with @SteffenR that his pickup or DI box or other gadget is the problem not the Qu.
@Volounteer
What age are you if you don’t mind me asking?

Hey all sorry for the Delay in responding, had to work all week and haven’t had time to mess around with my setup. Im going to try today all of the suggestions listed above and the info i got from the A&H Video and hopefully resolve this. I hope to write back later today with good news. Thank you all for your continued assistance, it has been extremely valuable and i am grateful for your help.
So as I suspected, the problem with the audio was facebook itself and not the mixer or instruments attached to it.It seems facebook cannot stream high quality audio direct. I discovered that by using a program called OBS allowed me to use the desk to stream live to facebook without any audio issues. The only issue I discovered now it that I get the occasional popping noise in the stream on the computer, but it is not registered on any of the sound meters/channels of the desk. Investigation continues on that front. Thank you all for your help, it is truly appreciated and I hope your all staying safe.
@Keith2581
OBS is a good choice.
Depending on what other software is running NEEDLESSLY and your buffer settings for the driver the popping sounds like a typical problem caused by buffering seamlessly.
Win 10 is a big culprit in running lots of crap you do not need and that will mess up audio.
But if you are using a tablet then I would have the same concerns about processing ability in RT.
I found this thread today and I am having a USB streaming issues … with a twist.
As I understand, whereas Windows requires driver installation, Mac Core Audio is supposed play right out of the box.
I have flawless audio from a 10 year-old Dell Precision laptop running Win 7 Pro.
I have a pulsing distortion from my late 2013 Macbook Pro that rides on top of the audio … sort of a high frequency rhythmic delay.
Both are using the same audio off of a Samsung T5 external drive and running the same programs to play the audio.
If I output the Macbook through its headphone jacks into the 1/8th mini jack and stream local the audio is fine.
FWIW I have only recently been using the Macbook Pro. It is running latest OSX with i7 and plenty of RAM.
Any speculation or resolution for this issues obviously greatly appreciated.
Thanks …
@DFT
win7 works great! we use it at our church.
newer PCs have more problems with audio.
Latest macs included.
Your old mac should be usable. But you need to fix all the problems that these devices have.
There are huge checklists for PCs about what to do to get them ready for audio.
I do not use the mac but there should be lists for them out there too.
