The cable between the K2 microphone and the K2 power supply (PSU) uses a standard 7-pin XLR connection. Whilst not widely available, many good professional audio shops should be able to get hold of the parts to make one for you. The cable is pin to pin.
Please be aware that you should only use good quality cable and connectors for connection between the PSU and the mic. Replacement cables are available from RØDE through our chain of distributors, RØDE can only supply the cable in a standard 10m length.
