Nord Stage 4 high pitched noise outputs

[Goldberg]

Hi, I am new here. I recently bought a Stage 4. There is a soft but definite high pitched noise on the outputs of mine (unrelated to the patch/sample) when playing. It's actually a high G note. Anybody knows anything about this?

In the example you hear me playing two different piano samples, some organ and a soft pad. You can hear it on all fragments. It sounds like something is wrong in the D/A converter

Update: it seems to be a resonance in my room somewhere
Don't hear it on headphones..
Sorry to bother you

Rooms will do stuff like that…no need to apologize
