MisterGreen Posted Friday at 05:00 PM Share Posted Friday at 05:00 PM (edited) I just got a new interface for my new build and I'm noticing a faint buzz or static coming out of my HS-50's (but strangely, not from my Event TR8's). It gets worse when I move my mouse around. Whether the interface is on or off, it's there. I've isolated it to the USB-C connection. When I unplug the cable, the noise goes away. I've tried 3 different USB-C connections on the computer and even one of the Type A connections with an adapter, with no luck. Also tried unplugging the display power and moving one of the HS-50's away from the computer. Has anyone ever experienced this? Also, you don't hear it through the headphone outputs; only the speakers. Edited Friday at 06:51 PM by MisterGreen Link to comment Share on other sites More sharing options...
Wookiee Posted Friday at 05:27 PM Share Posted Friday at 05:27 PM Try a different USB cable, or even try ferrite beads. Link to comment Share on other sites More sharing options...
OutrageProductions Posted Friday at 05:32 PM Share Posted Friday at 05:32 PM You've got electromagnetic field issues which are common in consumer grade audio electronics. Make sure that power & audio/data cables are not physically laid in parallel, move things around to minimize noise, and use a USB cable with a ferrite choke on it.

Regarding that, none of the cables have moved and this wasn't present with my old PC. Link to comment Share on other sites More sharing options...

The principles of physics and magnetism still apply, regardless. Link to comment Share on other sites More sharing options...
Amberwolf Posted Saturday at 02:45 AM Share Posted Saturday at 02:45 AM (edited) Presumably the speakers are powered from the wall AC sockets (the headphones wouldn't be), so you may have a ground loop; this would only be audible in the things connected to the wall. Is the new computer a laptop? If so, unplug it's ac adapter and see if ti goes away. if it does, you can get isolation devices for the ac adapter (1:1 transformers that go between it and the wall) that should fix this. If it's a desktop then you don't have the option of unplugging it, but you could move it to the same outlet as the speakers as a test. Also, if the interfrace has it's own ac adapter, *that* could be the source of the groundloop. Edited Saturday at 02:46 AM by Amberwolf Link to comment Share on other sites More sharing options...
