Parasite (noise in monitors issue)

[tim.huggiers]

The problem is coming from the cable. I have 2 JBL lSR 305 speakers. If I plug them with my PC I hear the parasite sound. But once I unplug them the parasite sound disappear, does this mean I have to change the 1/8 Y cable? It doesn't make sense I bought them 2 months ago. What am I doing wrong?

Connect the PC to an audio I/O interface (via thunderbolt or USB etc). https://www.sweetwater.com/insync/au...de/#definition Then, patch 2 quality balanced cables from the balanced +4db audio I/O interface L/R outs to the speaker balanced ins.

Indeed...the mini TRS output of most computers is garbage, so plugging that into any studio monitor is likely to produce louder garbage. Using a real interface and balanced cables is going to give the best results
