Hello,
I have a problem that I don't know how to solve. For some reason I can't get "even" sound. By that I mean some songs vocals are less loud than other parts. I have attached two audio files. First one is PC>T.Racks 4x4 miniDSP > T.Amp E-800 Vocaroo | Online voice recorder. Another one PC>T.Amp E-800 Vocaroo | Online voice recorder. Song link Search | Universal Production Music. Can someone explain what is going on and how to solve this? As much as I understand I lack output from my primary source (PC), which Impedance or vRms?
Cheers,
Entas

They were mixed that way.
First one music overwhelms voice, second one is almost right but music could be slightly higher.
Try again rising its level a little and you´ll be happy with results.
That´s what mixers are for, physical or virtual.
IF your Vocaroo service does not provide for adjustments, sing closer to microphone or further away as needed.

I feel like I cant explain this properly. So lets start with this. This is the sound levels i get from my speakers that are amplified by the T.Amp E-800. I recorded the same song played through the system. The first one is PC>DSP>T.Amp>Speakers. In the first uploaded file that is 1:15 you can hear that vocals are not even, but you can hear most of them. In real life the difference is immense. Feels like someone is adjusting the volume knob. Thats why i uploaded the song in order to make a comparison how different it sound through headphones (by readers) and through my system. When I recorded the sound levels PC>T.Amp>Speakers (second link) the song only has a few words while playing at the exact same volume configuration. This doesnt happen to all of the songs I listen to, but most of them. Some of the songs sound perfectly, but all the other ones sounds like someone is adjusting the volume knob. Vocals are all over the place. Im not comparing vocals to the instrumental. The problem is that vocals doesn't have any consistency listening through my setup. While i listen through PC>Headphones everything is fine.

If the headphones are fine, then it is either your room acoustics, or the speakers.
Play in mono, and see if you get a point center image, which is necessary for adequate
stereo playback. What speakers do you have? Do they have adjustments on the back?
Can you hear all the drivers in each speaker?

I have Visaton FRS8M (MLTL), Dayton PA130-8 (MLTL) and my friends Visaton BG20 (Bass Reflex). All of them have the same issues listening through my system. When I listen to my speakers at my friends place they are perfectly normal.
Can you post a floor plan of your room? Do the problems lessen if you move the speakers close together?
Are you near a wall during listening? How far away from the speakers do you sit?
Try listening in the near field, about as far away as the speakers are apart. Does this help?

So it's not the speakers, not the source, so only the near-1kW T.Amp E-800 amp is left. Powering a 3.3" speaker? Maybe try a bit less over the top amplifier...
A pink noise listen might confirm what you hear. Get a .mp3 file from the net (I found a 15 minute one) and one of those spectrum analyzer apps for your phone. That should let you see what, if anything, is happening in the midrange for the whole system. You can look at spectrums at different SPLs - be careful not to fry your drivers!

#7 Room is not the problem i have tried everything you said. #8 I'm not frying anything. I know how to use volume knob. I'm using 1/4 or 1/3 of the volume knob to power Visaton FRS8M and its perfect. For comparison my 150wRms subwoofers need more than half of volume knob to even start making somekind of noise.
Then you have ruled out all the possibilities, which means that you have made a mistake.
The most likely problem is acoustical, if the problem is similar with several different speakers.

A wild guess here, most likely wrong: are you certain the ground (common) connection to the speakers is present? If the ground connection is missing, the signal presented to both speakers is the difference between left and right channels and probably very strange.
Another experiment is to combine the two channels into a common mono signal and see if there's difference. Still another variation is to drive only one speaker for comparison.
Good luck!

You may be onto something there - note how the t.racks 4x4 has TRS balanced inputs, and the OP did not state how exactly he wired up the PC in terms of interface and cabling. If you plug a stereo output into a (mono) balanced TRS, guess what, you'll get L-R only.
I hope the OP won't mind either
a) wiring up their own 1x 3.5mm stereo to 2x balanced 1/4" TRS adapter cable with shielded twisted pair cable stock:
Left (tip) --> Cable 1 hot --> TRS 1 tip
Right (ring) --> Cable 2 hot --> TRS 2 tip
Ground (sleeve) --> Cable 1 cold --> TRS 1 ring
+ --> Cable 2 cold --> TRS 2 ring
+ --> Cable 1 shield --> TRS 1 sleeve
+ --> Cable 2 shield --> TRS 2 sleeve
(Instead of soldering all this mess to one jack, it may be more handy to cut a 3.5 mm cable)
-or-
b) buying a Behringer UMC202HD, Focsurite Scarlett Solo or other similar audio interface with two balanced 1/4" TRS to 1/4" TRS cables
-or-
c) buying the following: 3.5 mm stereo to 2x 1/4" TS cable + Behringer HD400 + 2x balanced 1/4" TRS to 1/4" TRS cable
A music store should be able to help out with (b) and (c).

PC > DSP connected through this pro snake 20008-0,5 – Thomann UK and DSP > Amplifier through the sssnake MXP2015 – Thomann UK. Did I do some kind of mistake?
Yes I did mistake with cables. Fixed it by choosing in Realtek Audio Console to play only one channel. Everything now works perfectly.
ummmm.....after reading through this i'm still left wondering if sgrossklass's premise is correct and somewhere in the system there's something amiss with phase of the incoming signals....could still be the result of a miss wired speaker producing karaoke like cancellation,no?
DSP inputs are mono either balanced or unbalanced. But PC output is always in stereo. That's why I had this "cancellation" effect that sounded so weird. I changed PC output from stereo to mono (leaving only left or right channel turned on) and it was enough to fix this problem. I just bought wrong cables. I had to go for 3.5 mm to 2x6.3mm and everything would have been fine. When im using my Xiaomi Pocophone as music source I just use the option "Mono Audio".
