Note: AD-C1200 comes pre-wired, from the factory, for transformer tap applications. To bypass the transformer see “Remove Transformer from the AD-C1200 Circuitry” in this section.

1.Locate and remove the five-pin Euro-style connector plug included with the loudspeaker baffle assembly. Typically it is plugged into its mate (J2) on the loudspeaker baffle assembly PCB.

2.Using a #1 Phillips head screwdriver, loosen the M3 wire retaining screws on the plug to provide enough room to insert the tinned wires.

Note: Do not remove the two-pin Euro-style connector (J1) plug with pre-attached wires.

3.Locate the wires coming from the ceramic terminal block in the AD-C1200BB back box and strip them to approximately 0.4" (10 mm). Tin the wire ends.

4.Insert the wires from the ceramic terminal block into the five-pin Euro-style connector in their proper connector position based on your transformer tap requirements. The negative wire goes to the COM connection, which is marked with a black dot.

Note: Transformer settings are also labeled on the bracket for easy reference.
