@Hilmar: I understood the question differently. I thought the OP wanted to know if it's OK to just use sos (given that you have both, sos and gain). Re-reading the question, your interpretation probably makes more sense. However, in that case reading the Matlab documentation would have solved the problem for the OP ...

If you use two arguments all section are scaled so that $b_1=1$. In either case you get the same result | |
