*Static noise

[theFOoL]

Hey guy's,

Look I bought the Acemagic S1 and I have to I mean I have turn on the 775 Build to even stop the static *somewhat "a little tiny hizz" but Bare in mind it's this Logitech 2.1 I got years back from my Brother *RiP but Yeah. When I Dial the sound ofc it makes static Loud teehee but anyway to fix it?

LOL I should of Chat gbt. It's known to

I mean, who hasn't?

 

[theFOoL]

What?

Heh, as old as my Logitech x240 is you'd have to expect but anyways I'm going to clean the Nob

I said "What?" because I really have no clue what you were complaining about. What does the Acemagic or 775 have to do with anything? Or Chat gpt? Or why did you quote yourself? I could not tell if that was a legitimate post, or not.

I don't expect static - I don't care how old something is. Have you tried a different speaker system? What about headphones? Does it only happen when you turn the knob?

I will note that the gain (volume) potentiometer (control) on older Logitech speaker control boxes are known to wear out and sadly, replacements are not available. What I did with my own 24 year old Logitech Z560 THX system that sometimes made a very loud and horrendous noise when adjusting the volume was decrease the speaker system's input gain using Windows own volume control. This then required me to turn up the gain on the Logitech controller thus using a different (not worn) spot in the potentiometer. No doubt in a couple years, that spot will wear out too. But in the mean time, they still, after all these years, sound great, without any hiss.

Meaning the 3.5 aux can have interfere sir but yes I clearly need to clean the Nob (I just turn it when I don't hear it) *Indeed swiping the knob will help abit as GBT said to solder a new knob but I don't have the skill to solder

 

[Bill_Bright]

It is not the knob but the potentiometer (variable resistor) behind the knob. Finding the correct suitable replacement potentiometer, one that has the same electrical characteristics as well as physical shape to properly align and fit in the mount location, has been the challenge.

If you power off, then twist the knob back and forth a bunch of times, that can, in some cases, clean the contacts of any dust and debris that may be contributing to the unwanted noise.

HOWEVER, in these cases with these affected Logitech controllers, the problem is not dirty contacts but worn contacts. And no amount of cleaning will repair that damage. In fact, additional cleaning just adds to the wear.

I noticed that if I have the pc in sleep mode then turn it on it has a static sound so I have to turn off/on but yeah my going to Look in a replacement

Hmm... I may look into it (searched a image)

How about a separate soundcard? Which board you have there and do you use the rear audio jack or the one in the case?

I have myself a cheap USB DAC what I use if I encounter a PC with crappy outputs.

That PCB is the Logitech X240 controller/Audio outputs. I have the main Audio connected to the 775 Build and aux to the ACEMAGIC S1. I only Hear static when I turn the knob

Ah, that's somewhat normal with potentiometres. So there's no static if you just put it to a position when it doesn't make static noise?

 

[theFOoL]

Indeed yes sir. I kept this 2.1 beast of a sound/Bass system only bc my brother picked it out from officedepot years back in... 2008

 

[Bill_Bright]

Something else not good is happening with that PCB. Note the excessive heat damage towards the bottom near the 2 resistors, diode and cap. I don't see evidence of excessive heat on those components so it might be from a source on the other side of the board.

Anyway - something is causing excessive current, and that typically means a short somewhere.

 

[theFOoL]

Hmmm probably yes. If I come to it to take apart the controller I'll let y'all know

Like on my Logitech x240 is it possible something is causing interference when I turn the knob or is that normal

Yes, interference when turning the volume knob on your Logitech X240 speakers can happen, and it's often normal for older or budget speaker systems. Here are some common causes and solutions:

Possible Causes of Interference:
Dirty or Worn Potentiometer (Volume Knob):

Dust and debris can build up inside the knob's internal contacts, causing crackling or static when you adjust it.
Solution: Try using an electronics contact cleaner (like DeoxIT) to clean the volume knob. Spray a small amount while rotating the knob back and forth.
Electrical Interference:

Devices like routers, phones, or even power cables nearby can create noise.
Solution: Try moving the speaker cables or nearby electronics to see if the noise lessens.
Ground Loop Issue:

If your speakers are plugged into a different power outlet than your PC or audio source, a ground loop can cause buzzing or static.
Solution: Plug everything into the same power strip or outlet if possible.
Loose or Damaged Cables:

Faulty or poorly shielded cables can pick up interference.
Solution: Check all audio cables for damage or replace them with higher-quality ones.
Aging Components:

Older capacitors or internal components may degrade over time, resulting in noise when adjusting the volume.
Solution: If cleaning doesn't help, internal component repair may be needed.
Best First Step:
Try cleaning the volume knob with contact cleaner — it's usually the easiest and most effective fix for this type of issue.

Still looks like a good 2.1 set, I hate that I sold my Creative P380 2.1 set which I had as a teen. That was without a doubt maybe the best speaker set for 50EUR back in the day.
