Logic
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, EXOR (exclusive OR).
The three functions are available simultaneously at three outputs with LED display of the output states. Additionally two inverters are avaliable 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 work no longer.
Applications: combination of digital signals of the A-100 (e.g. gates, clocks, triggers), e.g. to obtain "gated" clocks or certain rhythmic patterns.

Flexible operations
SumDif is a dual adder/differentiator module capable of handling both CV and audio signals. If you send a 3V signal at the A input and a 1V signal at the B input, then the A+B will output 4V while A-B will output 2V. Numerous applications, like unity mixing, buffering and inverting, can be achieved; you can also experiment with Mid/Side audio processing ! The SumDif has a precision signal path and can process V/oct signals perfectly. The two jumpers on the back side allow to reduce the A+B and A-B outputs gain by 6dB.
Features
• Dual 2 inputs adder/differentiator for CV or audio (For example if the first input is 3v and the second output is 1v, sum output provides 4v and dif output 2v)
• Each section can be used as as a 2:1 unity mixer, a 1:2 buffered multiple or a signal inverter.
• Mid Side processing application
• Optional -6dB gain for the first section
