Doepfer A-166 Eurorack Dual Logic Module
Doepfer A-166 - Dual Logic Module
Doepfer's A-166 is a dual logic module with 3 inputs for each unit. The logical states of the inputs ("1" = high / "0" = low) are linked together in 3 ways: AND, OR and EXOR (exclusive OR). The three functions are available simultaneously at three outputs with an LED display of the output states.
Additionally two inverters are available to obtain the inverted functions NAND, NOR and NEXOR.The sockets of each triple unit are 'normalized', i.e. the switched contact of socket 2 is connected to input 1 and the switched contact of socket 3 is connected to input 2. Provided that no plug is inserted into socket 1 resp. socket 2 the socket is connected to the input above it.
This simplifies the usage of the module when only 2 signals are combined. E.g. the logic functions AND and OR have different neutral input levels ("1" is the neutral state for AND, "0" is the neutral state for OR). In case of a fixed input level for the unused input one of the functions (AND or OR) would no longer work.
This module can be used to combine digital signals from modular synths (e.g. gates, clocks, triggers) to obtain 'gated' clocks or certain rhythmic patterns.
