Hello
I have this line input (pict attached) and want to change the gain setting
do I have to consider the IC working "differential" with:
NFB = - R108/R(TrafoSecondary)
FB = 1+ (R109/R107)
If yes the gain should be equal right ? so If FB gain = (1+(3K9/100) = 40
, Rtrafo is about 107.5 ohm (4K3/40) ?
