What is the maximum number of players that can be connected to one controller?
No known limit; however the cord length limit (around 70 feet) and the physical logistics of grouping many players suggests a workable limit of around 30 players, for example. When using high numbers of simultaneous players, it is advisable and more manageable to group the players in teams of 2 or 3 persons and make a single player buzzer unit centrally accessible to that team.
