Mopho is rattling

Mopho is rattling
« on: September 21, 2016, 06:15:49 AM »
Hello guys,

at the start: I am absolutely new to synthesizers, please keep that in mind. I just bought a mopho keyboard and its my first synth, so my problem might be pretty easy to solve.

The problem: everytime I play a sound my left speeker is rattling/murmuring. this happens more often if I play low/mid tones. Is there a setting I need to change? I already tried setting everything to 0, but still the rattling is hearable.

There are some experiments you can do to track down the source of the problem:

(1) Does the same rattling appear through headphones?

(2) If you reverse the left/right output jacks (so that the right output goes to the left channel, and vice versa) does the rattling stay in the left speaker, move to the right speaker, or go away?
