+It has 2 channels
+It will have an inpedance of 15K when the input pot is 0
+It has a minimum gain of 2.6 ((300x10^3)/(100x10^3)+(15x10^3)) and a max of 20 ((300x10^3)/(15x10^3))
+
+The gain is almost correct, although its minum is slightly too high
+
+A correct value would be to use a pot with a maximum impedance of 135K.
