interference

Problem: When computer off, very quiet white noise from speakers. When computer on, nasty electrical noise when idle. When computer doing heavy work (CPU or GPU, probably power draw related), absolutely awful squealing. This has been a pain for years, and finally remembered to try out using a...

My Denon HEOS Link2 streamer receives from our router over the 2.4 GHz wi-fi band. When we run the ~1200W microwave, its radiation interrupts the stream. I pass on a solution I found. The router was set on Auto channel, that is, its firmware algorithm chose from channels 1 to 11 in the 2.5 GHz...

I am using a Topping D10 Balanced with a Sabaj A20h and I just found something really weird, I am picking up FM radio interference but only on 3 separate volume spectrums, between -99dB and -85dB, between -3dB and -1dB, and at 0dB. Between -99dB and -85dB is the strongest, I can no longer hear...

How can I convert this ↓ TO THIS ↓ I have them ↓ and necessary soldering equipments...

Hi All, I'd appreciate some advice as I re-educate myself. I'm contemplating a re-organisation of my setup, possibly starting again from scratch - I'll save a fortune on interconnects now :) Anyway: I may end up with a number of boxes; streamer, dac, phono-stage, pre-amp, power-amp. Possibly...

Hello ASR, I need some help in choosing some new interconnects. My currently owned very cheap RCA cables that cost me £8 a pair from Amazon are emitting a high frequency whine *through my speakers* tweeters (sounds like tinnitus, 16khz or higher) from both my Fiio k3s and RME ADI-2 FS dac. The...

Hey guys! So I'm turning to all the amazing, knowledgeable and wise people on this forum. We've been picking up a swelling interference noise in guitar amps and rhodes in the studio. Been trying to see if the problem is internal, which it probably isn't. I've come to this conclusion by cutting...

I think I need heavy ammo in shielding my office music hardware, and don't know how to narrow this down. Like a gigantic Faraday cage? Tin foil hats for all equipment? Victrolas? Most of my listening is done at the office. I use both a portable DAC/Amp and a desktop DAC and Amp to listen to...

Test of RFI circuit susceptibility to AM modulated signal with 1MHz carrier Well – this was tough. I wanted to test possible susceptibility if input analog circuits to AM modulated signals like AM transmitters etc. Sometimes we hear complaints about audio equipment capturing and demodulating...

Hello, I've had weird static noise when using headphones on my PC for at least a year or two but it is starting to get really annoying now so would like to sort it out. Currently using a Soundblaster Z internal soundcard, with my Sony MDR-1AM2 or Fidelio X2HR plugged into the headphone jack of...

I have some pretty nice xlr cables right now. Probably way overengineered than necessary, Pangea Audio True Balanced xlr cables. I have heard there is some evidence that Star-Quad XLR cables reject interference better than other designs. Would upgrading to star quad xlr cables provide any...
