"S lead" Master to slave have same pins - a "M lead" is different, it goes from speaker to component piece,(180 deg to 240 degree end connectors) - Master to slave speaker connectors are the same 180 degree ends - I was able to go to a music instrument store and get 5 pin din midi cables that worked perfectly (had all pins wired)for $25 for a 15 foot.They also had long runs of shielded coax that worked perfect for the digital input/out
