Screw the hold-down screws on the connector until tight, using a small
screwdriver.
You can connect the speakers in the two following possible layouts:
Wiring in parallel: connect the wire pair of the subsequent speaker to
PIN 2 and PIN 3. When one input connector is removed, subsequent
speakers will remain connected (see
Figure 3)
Daisy-chaining: connect the wire pair of the subsequent speaker to
PIN 1 and PIN 4. When one input connector is removed, subsequent
speakers will be disconnected (see
Figure 3)
5. Plug the connector into the socket in the terminal cup of the speaker (see
Figure 5).
6. Run the wires through the wires’ opening in the input terminal cover plug
and then into the terminal block connector of the speaker.
