Doepfer A-166 Logic Module
- Order number: 120154
- Depth: 50
In this module we find two sections which work with the principles of Boolean Logic. Each has three inputs with their logic states ("1" = high / "0" = low) being compared, combined and finally output at three logic outputs: AND, OR and exclusive OR (EXOR). In addition there are two logic inverters for switching the logic states.
The A-166 is a really good module for combining and linking digital signals like clocks, triggers and gates.
The three inputs of each section analyze which digital states are present at the inputs. The inputs are normalized (1->2->3) so it's possible to work with less than three input signals.
In each section three outputs of logic functions are available simultaneously:
- AND: Output goes "high" when all inputs are "high".
- OR: Output goes "high" when at least one input is "high".
- XOR: Output goes "high" when a odd number of inputs is "high" and the rest is "low".
The logic inverters can change the aforementioned functions into NAND, NOR and NEXOR.
n.b. a logic inverter turns a "0" into a "1" and vice versa. It does invert the logic state, not the voltage value (i.e. +5V will not turn into -5V).

A-166 @Doepfer
WIth a long trajectory building synths, MIDI keyboards and designing bespoke devices for music pioneers Kraftwerk, Dieter Doepfer decided to design his own modular synthesizer in 1995 based on existing electrical and mechanical specifications of lab equipment he used during his years at university. The official presentation of the system at 1996 Frankfurt Musikmesse caught everyone by surprise and created lots of interest. After Doepfer published the specifications on his website, many instrument designers and engineers saw the potential of the new Eurorack format. Doepfer continues expanding their catalog of over 200 modules (and counting), operating from their modest offices in the outskirts of Munich.
