I've observed that on many dirt-cheap speaker systems and promptly found this, but don't know why that happens.

Re: Vocal range sounds like crap when adding too much bass
Either because the low-powered amps in these things are driven into clipping when you turn up the bass, which not only results in distortion, but also makes the bass modulate the rest of the frequency range (giving a rough sound and a "warble" effect to the vocals), or the speakers don't have enough linear travel and are forced to move too much, which gives the same effect, only not that pronounced.
Either way, an oscilloscope will tell you what happens. Using one of those programs which allow you to turn your PC soundcard into an oscilloscope will work too. Visual Analyzer is my favorite.A working TV? How boring!Originally posted by PeteS in CA -

Nice! Seriously, thanks for the info
. I've been looking for something like that for a while now.
The headphone amp I built seems to be doing a similar thing with the mid tones being distorted when there is too much bass and the volume is very high. I think it may be my headphones though - I'm probably pushing them too far

OK, this one dates back to 2015! I thought I had posted this, but realized I didn’t when I posted a picture of something else. So here it goes…
Back in 2015, I bought a pair of RCA WHP141 wireless headphones at Micro Center for $2. I even mentioned it in the best cheap/free scores thread right here. Just forgot to follow up with that.
As mentioned back then, these are (were) 900 MHz FM wireless headphones. No modern day Blutooth or anything like that. I knew they wouldn’t be great headphones or even that good… but the price was right!
So let’s take...

I'n trying to fix a M&S SYSTEM DMC-1which have following problem:
I'm using FM station to do this fix, I works perfect if volume below around 8 or if bass is set to zero, the sound can go to 20 without problem, but if I set bass to maximum and try to go over 10 the sound comes distorted ... I saw a video on YouTube the person saying about the main capacitors on the power portion, but I disconnect the main transformer and inject direct to the capacitors PINs my bench power supply -23v 0v +23v, but still distorted so I think the problem is not the capacitor neither the transformer... -
Hey guys,
Hope you all are doing well. I come here from Win-Raid because I am having issues disabling Flash Protection Range Registers so I can flash my BIOS from within Windows using Intel's IFW tool/using flashrom within Linux, however I cannot due to the above mentioned error.
Here is my thread on Win-Raid detailing the whole process I went through: https://winraid.level1techs.com/t/re...h-gen/95478/27
Essentially I managed to boot into Windows while shorting PINs 1+5 of my audio chip to disable the HAP bit... -
I thinking to modify some ATX ver 1 supply, and wonder what if I connect 10k pot on 12v and center tap on brown wire? What range of 3.3v correction can to expect, or something will blow up if I close to rails, leave narrow 3.3v range?
It is KA7500B ic, but 3v3 sense is connected to TL431, I am not sure there is any connection between. -
