master / slave digital cable for 440Pro

I think the whole system sounds (slightly) cleaner, although the more I listen, there are improvements

I have copies of the SD cards for both iterations (RCA-RCA and RCA-AES) so with not much trouble, its quick to change

I noticed a micro-switch on the AES socket which connects or disconnects some part of a circuit when an XLR plug is inserted
