The speakers have an external power supply. This is plugged into a four way plug, which is plugged into the wall socket. The power supply plugs into the right speaker (which has the amp inside it) and a lead goes from the right speaker to the left speaker. My SB3 is plugged into the same four way plug as the speakers' power supply. Nothing else is plugged into the four way adapter. The SB3 is wireless, so has no other connections going into it. The SB3 is plugged into the right speaker via an rca interconnect, with an rca-minijack converter at the speaker end. I've tried using a cable with 2 rca at one end and a minijack at the other, and got the same hum.
After speaking to a techy guy at work, I'm going to connect one of the speakers audio inputs to ground (a radiator or the earth pin on a socket) via a resistor. This will hopefully have the same effect as me standing there with my finger on the connector.
