Doepfer - A-100 Bus Board V6
Bus board for connecting a maximum of 22 Eurorack modules. LEDs indicate whether the correct supply voltages (+12V / -12V / +5V) are present. Four cables for connection to the power supply unit are included in the scope of delivery. The new version of the A-100 bus boards (labeled Version 6 / 2019) uses tub pin headers that are equipped with reverse polarity protection in the form of a recess for the "nose" of the socket on the bus connection cable.
Since January 2016 the bus board is delivered with four connecting cables. For that reson it's compatible with the new switching power supply PSU3, which carries four secondary voltages (+12V, +5V, -12V and ground [GND]).
Of course it is also possible to connect this bus board with three cables only to older Doepfer power supplies which don't generate +5V.
