Yes, there is no need to worry! The 5 pin DIN plugs fitted to our Aux Input Cables and RCA Input Cables will fit perfectly and work correctly in both 5 pin and 7 pin DIN sockets.
The extra 2 pins in the 7 pin socket are only used to pass data between B&O products, so they are not required when non-B&O inputs are connected. The alignment of the pins is identical for both type of sockets, so the 5 pin plugs are ideal for both the older (5 pin) and the newer (7 pin) input sockets.
