HOw to minimal Hiss ? Pc sound still hiss. suggestions?

[audioloveryes]

Hi everybody

I have been enduring a hiss sound( speaker on but music player off) from lantec 5.1 pc speackers for years and it was driving me crazy so i asked chat gpt how to solve , he made me buy
BESIGN Ground Loop Noise Isolator, Buzzing Noise Filter, then Plugable USB Audio Adapter Adds 3.5mm(USB sound card (DAC )i beleive) it changed nothing.

It then pointed out the edifier mr4, 250 dol which I bought and just received and could return. They have less Hiss noise yes but still I would like less. Plugging it in the usb plugable did nothing.

JBL 305P MkII speaker with its internal amp( 280) is then what he recommands me

0) would this setup have less hiss than the mr4? Certain? Mostlikely? Not or more hiss?.

-----

it then says that passive speaker have less hiss. And suggests, me fosi audio v3 mono(189$) with One

passive speaker or fosi v3 with 2 passive speaker. I then tell chatgpt that i have an 20 old jvc JVC UX-T1 Micro Component System( 2 speakers 8omh 15watt each that only are connected to the central part with 2 tiny wires so probably passive. See picture

He tells me that i could use a fosi v3(not mono) to plug them and it is not sure if it would be less or more hiss.

1)What do you think?

.2)Which of those setup have less hiss than the mr4? Certain? Mostlikely? Not or more hiss?

3) or other suggestion around 250 -300 dol

-What is written behind the speaker is ux-b1005, part no vg ss005 -11, power handeling capacity 15w max. Victor company

Buy refurb Adam Audio D3V for $280, connect via USB, problem solved.

Your hiss problem doesn't sound like a ground loop. It's just regular old noise from the amplifier section in your speakers. To get rid of it, you will have to get either active speakers without audible hiss (check forums for user reports) or get an ultra low noise amplifier + some passive speakers.

I'm sure some members can recommend hiss-free active speakers - I don't have any experience with those. But I know based on my setup that passive speakers combined with either a Topping Mini300, an 3e Audio A5 (or A5 SE) or Topping PA5 II will be totally silent unless you press your ear onto the tweeter. As speakers, you can temporarily use the crappy JVC ones you already have and upgrade down the line, as soon as you have some money to spare. Some used KEF LS50 might be an option, but there's many more.

From my (limited) experience (see spoiler below) - there is no such thing as a completely hiss free active speaker. Or a hiss free (cheap) amp.
Some listeners will be more sensitive than others, and a noisier room will mask it, but it is there.
To differentiate, you would have to turn on the speakers (or amp, if passive) without any signal source and then listen.

I'm struggling to unravel the original post.
I'm thinking you are playing music on a PC, using some kind of media player. You have some kind of amp and speakers plugged into the headphone output socket on the PC.

If so, the little amp on the PC will generate hiss to headphone port, whether you are actively playing music or not. Then, many modestly priced amps will likely add even more hiss. If you used a good quality amp to drive speakers, it will have no audible hiss if its own, but it will amplify any hiss coming from the PC.

IMHO, the best way to get good, hiss-free sound from a PC is to make sure you are sending only a digital signal out of it, usually using a USB port. If you do, you will need some kind of USB DAC to convert the digital signal to an analogue signal for your amp to use. Unless you have a good amp though, a cheap amp will still add hiss (as said) but at least that hiss won't be "PC amp hiss + main amp hiss" combined.

In my office, my PC connects to a Topping DX1 over USB and I feed it using exclusive mode from Foobar2000. There is no discernable hiss from either headphones or from a separate amp and speakers, driven from the RCA outputs on the DX1, when I prefer listening without headphones. There are hundreds of similar products that should give you less hiss, or none. If you have active speakers, you can plug them into the DAC (watch out for volume control though), but active speakers vary in the amount of hiss they may produce. A lot depends on budget.

Sorry if this is not your "use-case". But "digital out" is the only way to go with most PCs.

2nd generation (wave) Kali active speakers have pretty low self-noise (which is what you're describing). It's only audible to me VERY close to the LP-6 model I have - I'm talking 10-20 cm close from memory so wouldn't bother me in a normal desk setup.

Edit: just to say I have a pair that I use as rear-surrounds for 5.1 use.

There may well be quite a few active speakers with no significant hiss, but if the PC itself is injecting hiss, then better speakers alone may not be enough.

I don't know much about the various active speakers choices. I'm sure the Kalis are great.

It sounded more like a self-noise problem to me but you're right the OP should check.

@audioloveryes is the noise you're talking about reduced if you have no connection to your PC? Or no different?

Yes. The most likely source of the hiss is probably the PC itself so the first thing to do is to use a digital output from the PC so as to prevent that. You can then just attach either a cheap active system such as the one suggested by kyuu or if budget allows get a more capable/expensive active speaker system or separate DAC/amplifier/passive-speaker combination.

USB connections from PCs to DACs (and hence active speakers with digital inputs) are well-known for transferring noise from the PC. A Toslink connection wouldn't, and I'm not sure about the other digital connection optoins.

Well, mine is not. It's just a Topping DX1, nothing special.
While my PC's own internal amp/DAC produces hiss if you listen with 'phones plugged into the headphone socket, and also picks up all sorts of pops and clicks when the PC is busy, all of these are entirely absent when I go via USB to the DX1. In fact, I have used several USB DACs with various of our PCs, and all worked silently. Are thinking of a specific USB DAC that tends to be noisy?

No. It really is a well-known issue, sometimes associated with particular activities on the PC rather than just a constant thing. It's one reason DDCs exist to help isolate audio systems from PCs. It's not something I've every experienced myself though as I've never connected a PC directly to my audio system.

Well, you definitely do get pops & clicks (and hiss) if you do analogue out from most PCs (at least I have never owned a PC of such quality that this didn't happen!). Conversely, I've never had this happen on any USB DAC I've tried, but maybe I'm just lucky, or maybe it's not so common!

Yeah I don't know how common it is but do know it's a thing. And I do definitely mean via USB.

Do you get hiss from the speaker even with nothing connected to the speaker? Or does it only start when you conect the PC? What inputs do you have available to. your speakers - what input are you using?


EDIT : if this is noise from the audio system itself - then there is nothing you can do. If it is noise coming from the PC then there might be a lot. Which is why I am asking you to test with nothing connected.

EDIT some more: Does the hiss change when the graphics on your PC screen changes - eg when you move the mouse or scroll windows?

EDIT a third time: Do you have anything else as a music source you can plug in instead of the PC - to see if there is still noise from that?

Don't underestimate the number of people 'out there' who don't see the significance of identifying hiss, versus general RFI or bus noise pickup, or ground loop mains hum - it can lead to misdiagnosis, and expense, and may get mis-reported. (even on ASR, surprisingly). And people do the weirdest of things with kit sometimes.... My point is that if you listen to music on a PC, you should get a good experience with most of the common DACs.

Let's be a little nicer, especially to newcomers

Hello you all. While I consider our forum to be more friendly than many, it seems that we are quite harsh on new members who post things that go against our consensus view. There is no reason to pound on people hard when they say this and that sounds good to them. Let them have some time here...
