1 It has 2 channels 2 It will have an inpedance of 15K when the input pot is 0 3 It has a minimum gain of 2.6 ((300x10^3)/(100x10^3)+(15x10^3)) and a max of 20 ((300x10^3)/(15x10^3)) 4 5 The gain is almost correct, although its minum is slightly too high 6 7 A correct value would be to use a pot with a maximum impedance of 135K.
