Grainy sound in the highs drivers on voice only

[Lucifer1to10]

Hello, please help i am getting grainy sound on voice in my highs drivers no matter what i try i cannot find the source and get rid of it i have a google streamer 4k the connected to the tv and i am exiting from the tv optical also have tried hdmi extractor and exiting from there optical same problem ,the optical goes in to my Behringer ultra curve pro deq 2496 and exits analog(also tried connecting the phone directly to the amp using other cables same problem)to crown xli 2500 the speakers are 2 way eminence delta 10A for mid bas and eminece asd 1001B for highs horn drivers now had some no name drivers before same problem , had proel crossovers same problem now i got winford wf-2a80-k2 same problem, the grainy sound is just in the vocals and just in the high area tried disconecting the high driver sound is clear on the bas delta driver , tried connecting the delta directly to the amp sounds clear ,tried connecting the high driver to the amp and ading just a resistor and a capacitor 4.7 uf than 3.3 uf than 2.7 uf same grany sound tried connecting only the capacitor still same problem and everything is new ,so i have been through 2 sets of diferent high drivers ,2 sets of crossovers ,and i seem to get the same problem tried about 4 diferent amplfieres tried diferent sources,even on the laptop still same problem and this is from a low listening level from a few watts up to high power nothing is clipping in terms of signal i am out of ideeas tried smsl su-1 no matter what combo i try i cannot get rid of the grainy annoying sound if i listen to instrumental music like drums , saxophone,guitar ,guitar bass ,piano etc anything it sound clear the moment voice or dialogue are involved that is the only point where grainy sound appeares

Welcome to ASR. Please try posting again, but this time with some punctuation. I tried reading it and made no sense out of what you are trying to say.

Could you post some songs where this happens?

And please include a picture of your speakers.

How are you using the Eminence ASD 1001B? Which horn attachment are you using?

Recording quality ?

Have you listened to the same recording on hifi systems and did not hear 'grainy' voices ?

i put some pictures with the eminence asd 1001b i am using now , the horn, the horn adaptor,and the no name old drivers i was using befor the eminence , i will take better photos of the speakers once i get home ,the thing is it is not just on some songs it is on all music that has vocie /dialog,even on movies no matter what i am playing,as apps i tried youtube,youtube music, Spotify,tidal, for music for movies disney,netflix ,hbo ,prime the same on all of them, i got thick cables running from my amp to my speakers ,inside my speakers the same thicknes to the crossover and out of the crossover 2x5mm if i am not mistaking the size

 

[Lucifer1to10]

p.s mainly use them in the house so they rarely go to max power level ,most of the time i use them at 50% max level or below so i have a lot of headroom

no but, if i connect only the bas speaker through the crossover it sounds clear on voice,also if i connect the bas speaker directly to the amp full range i get clear voice that is what is puzzling to me ,that i get this grainy sound only on the high drivers brand new and i get it on both of them , i had the same problem with my old high drivers

I would think "grainy" means distortion, and if so, it would be most audible via the treble speaker.
Assuming you haven't somehow damaged the treble speakers, and assuming the source content can be shown to be relatively free of distortion, the you are getting analogue or digital clipping or the addition of some noise that is interfering at treble frequencies, or possibly a sample-rate or bit-depth conversion that is going wrong (or maybe multi-channel to stereo).
I'm not clear from the original post, but it sounds like the source material is going into a TV - can you plug headphones directly into the TV's analogue output and listen for the distortion? Or even listen via the TV's speakers to see if it's there too. Point being, you need to devise tests to try to isolate where the problem is coming from, and eliminate where it's not happening. Having said that, my money is on the Behringer overloading the Crown input. Are you using XLR or RCA to the Crown? It could be one of those devices is damaged, or just nasty!

[edit - This looks likes studio gear being used to play TV sound - is that a bit of over-kill? A low-cost streamer with an HDMI input from the TV should work more than well enough. Also, it's not beyond belief is that your crossover inductors are saturating if playing at volume - worth checking]

 

[Lucifer1to10]

well i tried taking the tv out of the ecuation using an hdmi extractor same result , also tried sending audio from my phone in to the crown directly using a cable jack-rca but got the same results,tried even using a preamplifier that has Bluetooth conection then exiting analog to the crown same result,so i tried already basically bypassing everiting and still it sound's grainy and at low volume too ,by this i mean even if i turn the input signal to the amp to below 50% , and my crown's signal input led the green ones barely blink ,i still get the same result it is kind of a distortion but more of a static sound ,like when you have an electrical wire that is not making a perfect connection , and it is very annoying because it is a thin refined kind of distortion , and to answer your question no i have not dameged the drivers in no way and my signal is not too hot it is not clipping on any of the devices, not even close to clipping... i will try to make a video see if i can catch it on the phone mic and camera

 

[Redacted]

OK, it's hard to make guesses at distance, and visualise your testing.
What I think I'm hearing is that when you use the phone's headphone-out socket directly into the crown (with absolutely no other active gear attached) you still hear the noise. Is there a way of trying that setup with different speakers? If you still hear the noise, then it must be down to the crown or the wiring to it. (I assume if you play the same material on the phone, and plug headphones in to it, it sounds fine, therefore eliminating phone and source material). Also try the rig on a different mains socket (a different ring circuit if you have those) in case the noise is main-borne.

 

[Lucifer1to10]

oh so you are thinking maibe it is the wall main power giving out high frequency distortion emi/rfi,yeah will try to plug the rig directly to another wall socket ,i haven' t done that yet from what i know i only have 2 wires coming out of my wall socket so i do not have a ground if that is what you are suggesting,oh and i also tried ferite beads on all the cables both power and signal cables i attached to them ferite beads but no results

 

[Andysu]

maybe a video as to what , grainy voice is sounding like , do at least few minutes with some commenting as grainy voice could be anything and use the what ever source it was that caused , grainy voice as i also have the DEQ 2496 there might be an answer , ( video only ) as this site is about science

 

[Lucifer1to10]

i tried recording,watch for the voice in specialy when the voice is raised and also on the vocal backround there is a fainth distorsion,hope u can hear it through the phone microphone,it is a movie dialog from "the boys" on prime but the effect is the same no matter the source

 

[Lucifer1to10]

video

 

[Andysu]

where's the video i can't see any posted video ?

grainy so not like grain rice , but i think more like a static hiss like rough like ? got get that video up at least few minutes , go though how you have the audio-sound-chain connected and in the video disconnect the DEQ 2496 and connect direct to source , ( get the idea ) there maybe a culprit that is producing the noise ?

additional , also do a silent with no source audio , can you still hear the noise , get up close good quality ( and please keep the video landscape )

i tried uploading last night a 3 min video i guess it didn't upload will try to make the video in a few pieces ,when i got no audio source everything is completely silent i don't get any hum or hiss

i don't get how i attach a video on here it just doesn't let me

You can't. They are too big.

You will need to put it on. youtube or similar then post a link.
