Dear BioSemi Team, we have recently had a series of issues with our 64 channels BioSemi Active Two system causing us to lose some valuable data. The problem seems difficult to replicate which is why we have not contacted you earlier. It occurs always in a while (every other participant or so) that i...

Thank you Coen,

With average reference the signal looks ok, however, with linked earlobes, the B-block channels look much noisier (i.e. high frequency ...
