I recently started w modular and use the Malekko 8NU8R to get out audio to my speakers.

The issue is that as soon as I (accidentally) thouch the patch cable from the 8NU8R to the speaker the speaker starts humming and I can only stop it by unplugging/re-plugging the speaker. I have different cables from different manufacturers--no joy.

When I patch the cable to my Focusrite 2i2 soundcard instead and from there through the laptop/PC to the speaker all is fine and there is no humming if the patch cable is accidentally wiggled.

How can I improve this?
