OVERVIEW:
2 stage, switched, cascading, logic module;
Up to 4 inputs & 12 outputs – simultaneously;
Unlinking gives 2 independent 6 part stages;
Link stages by CV & on-board switching;
RTL works on all input types – not just logic;
LED indicators for all inputs & outputs;
Power supply reverse-voltage protection;
Low-profile build mounts in any depth rack;
STAGE A:
1: NOR 1:
2x input (IN 1 / IN 2)
2: NAND 1:
2x input (IN 1 / IN 2)
3: NAND 2:
2x input (OR 1[A] / NAND 1[A])
4: OR 1:
1x input (NOT(NOR 1[A]))
5: AND 1:
1x input (NOT(NAND 1[A]))
6: AND 2:
1x input (NOT(NAND 2[A]))
STAGE B:
7: NOR 1:
2x input (IN 3 / Link A state (AND2[A] or Low))
8: NAND 1:
2x input (IN 3 / Link B state (AND2[A] or Low))
9: NAND 2 (Unlinked):
2x input (OR 1[B] / NAND 1[B])
XNOR (Linked):
3x input (OR 1[B] / NAND 1[B] / IN 3)
10: OR 1:
1x input (NOT(NOR 1[B]))
11: AND 1:
1x input (NOT(NAND 1[B]))
12: AND 2: (Unlinked)
1x input (NOT(NAND 2[B]))
XOR: (Linked)
1x input (NOT(XNOR))
PRECAUTIONS:
The ADE-31 uses the Doepfer standard for power connection and cable
orientation. The RED stripe on the supplied power cable connects to the
NEGATIVE (-12V) rail on the ADE-31 with the RED stripe facing DOWN.
This is marked on the back of the ADE-31 PCB as “-12 RED”.
The ADE-31 has diode and polyfuse protection built in but an incorrectly
connected cable may still cause damage to the module or the power supply.
The rear panel of the ADE-31 has exposed parts and connections. Please
ensure when handling the ADE-31 that the unit is held by the sides of the
front panel or the sides of the PCB.
