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.
