#groundloop — Public Fediverse posts

Any vintage hifi people got any ground loop tips? Weird thing I did not see coming: my TV has some influence on it, though I guess that makes complete sense; it is what's connected to the other ("AUX") input.
If I unplug one of the RCAs from my TV's audio out, the hum gets SIGNIFICANTLY LOUDER. Not entirely sure sure why that is; probably the fact that it has a massive ground plane and a chunky 3 pronged power cord doing most of the heavy lifting to flush that noise down "the holes" (really hope somebody gets this reference).

I'd probably just unhook everything, then eliminate the variable of power bars/extension cords, and then go one by one putting things back together and noting what happens, but my ancient plasma TV has bad caps that can make turning it on take anywhere from 10 minutes to a few days (so I guess they're *really* bad now, as of last time someone turned it off), so that power bar is not going anywhere til I either replace the caps, or the TV, lol.

🧵 The 2nd device is connected in both ways, and when both the PC and the other device connected to the jack inputs are on, I hear background noise when performing certain actions on the devices.

I used a ferrite ground loop isolator, but it was useless; not only did it fail to fix the distortion, it made the analog sound much worse.

What would you recommend for this? Do I really need to spend money on an external mixer/sound card? If so, I'd appreciate any suggestions.

I'm experiencing sound distortion problems when I connect two devices to the analog inputs of my sound system.

One of the devices is connected from my gaming PC using three jacks for 5.1 surround sound, and the other is connected either via analog from my Mac or through a USB-C dock to the monitor, using the analog output from the monitor.

“But do we get to play with safe opto-isolated geometry engines and invocation clusters here? Do we, fuck: we’re stuck with Dr. Volt and his thuggish friend Mr. Amp, and pray we don’t get a stray ground loop while the summoning core is present and active.”
