Looking for advice on wiring Krone block to DB-25

[morls]

As the title says, I'm trying to figure out how to get Krone disconnect blocks and (Tascam) DB-25 to play together nicely. The cable I've ordered for the short runs, less than 4m, is PSN20, 10 twisted pairs of 24AWG single conductor wire. With such short runs and using a twisted pair, is it possible to just use each channel's +ve and -ve pins, leaving the G pin for each channel unconnected?
