		+	Remark by jOERG: Please try to understand when you are using a different setting than control.63: Mic 2, you are using a whole bunch of function blocks from PGA and digital section and you are not considering how the settings of those function blocks impact on your results. The whole test report is void / useless if using left/right_PGA. Also, as elaborated here and in Talk, there's no benefit from using PGA routing (beyond voodoo).
