The full output of the mixer circuit is Vout = -Rf(V1/R1 + V2/R2 + V3/R3 . . . + Vn/Rn). Thus, by making RF larger the gain can be increased. The other option is to make the resistor in the channel(s) smaller, but you are already using a potentiometer that can become very small, thus increasing the size of Rf is a better choice.
