Korg Forums

I want to know how many people have this issue (very audible noise beyond the normal from headphone jacks) or if it appears on both type of machines.

Tested 4 units up to now for the distinct audible buzz with these modes switched on. Only one unit did not suffer from this issue, the demo unit in the shop, which I am keeping to make music on until a new unit arrives that works as it should,. Without the buzz noise.

Additionally my friends E2 also does not suffer from this issue.

I have raised my complaint with the vendor here in UK, they have taken this to Korg. It's bad news so many units are affected by this.

its faulty as it gets worse on power save and audio in thru, I noticed it even on the audio in osc, when you turn up the second gain stage from the osc edit knob, it gets really bad, like a feedback loop of noise, some units have been build with s**t components or something...

No noise issues here.

I take my vote back, I never use the audio in, I did today and at high volumes with audio in thru turned on its very noisy.

Mine is noisy. Clearly a faulty batch.
