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
