Auch andere User haben im Forum der JWsoundgroup nun darüber berichtet:
VGI have a massive problem with audio jumps on the zoom f6.
Audio jumps at some point and gets out of sync, you can clearly hear it in the audio file, so its not a syncing issue.
I testeed 5 different high quality cards and orderend two new ones to be sure its not a card problem.
As it happend the first time in dual record mode (32 plus 24 bit), Zoom claimed it should only happen in this mode, but right now it happend in 24 bit mode as well.
All "full card tests" on this recorder and its replacement failed in the recorder with seven good cards (for example sandisk extreme pro) that work well in cameras and in a SD mixpre 10 II.
So I guess its an issue with some new chips in newer models as I think they changed something internally due to corona shortages.
Other users reported problems as well, so dont rely on this recorder!
