B-020 Bool3 – logic module (4HP)


B-020 three input boolean logic module for Eurorack / Doepfer A100 system.

From top:
A Input jack + LED
B Input jack + LED
C Input jack + LED
AND, OR, XOR1, XOR2 and NAND/NOR output jacks + LEDs

three input level driven boolean logic module, outputs:
AND (all three active inputs makes output active)
OR (at least one active input makes output active)
XOR1 (just one active input makes output active)
XOR2 (just two active inputs makes output active)
NAND/NOR (inversion of AND or OR outputs, jumper selectable, jumper set=NAND, removed=NOR)

Width: 4TE/ 4HP/ 20mm.
Depth: 40mm /1,6″ max.
Current: 15mA max.
Power cable included.

Double check power connection before powering your system please.
„Red strip“ means -12V connector side in Eurorack standards.
In some power distribution systems connector key can be reverted.
In this case cut connector key and plug power connector right way (with respect to red strip) or use different power cable appropriate to your power system.
