Disconnect Transformer from the AD-C1200 Circuitry
If you are connecting the loudspeaker to a 16 ohm system, you must disconnect the transformer.
1. Unplug the two-pin Euro-style plug (J1) on the PCB
(Figure 25)
.
2. Loosen the two M3 wire securing screws using a #1 Phillips head screwdriver and remove the wires.
3. Secure and insulate all the wires you removed using a tie-wrap or similar device. This is to prevent rattling during loudspeaker operation.
4. Insert the wires from the back box ceramic connector block into the two-pin Euro-style connector and tighten the screws. Negative wire goes to the
COM connection which is marked with a black dot.
5. When you install the loudspeaker baffle assembly into the back box, plug this connector into the two-pin header connector (J1) on the PCB.
Note:
Transformer settings are also labeled on the bracket for easy reference.

Painting the Grille
An extra grille cloth is provided for use when the grille is repainted.
1. Paint the grille as desired. Allow to dry.
2. Grille cloth should be removed before painting. The grille cloth will have paint on it which reduces audio performance.
3. Attach the new grille cloth using 3M™ Super 77™ Multipurpose Adhesive per the manufacturer’s instructions
