I have an FBV Shortboard Mark II which I want to run into a Randall RM4 preamp/RT2 power amp. Since the FBV uses a straight cat 5 cable with one of those ethernet type plugs, it would require attaching a 7 point din plug to one end. From the Randall, din plug pins 3 and 7 carry the phantom power which is 9v ac 1amp. What wires in the cat 5 cable go where in the din plug? On a more general question, does anyone know whether the FBV will effectively communicate with the Randall?
