Installation Note: Connector Wiring Guidelines
The input connector's 4 terminals are numbered and marked on the connector. Pins 1
and 2 are positive (+); pins 3 and 4 are negative (–). (Pin 1 is connected to Pin 2 and
Pin 3 is connected to Pin 4 inside the speaker.) Pins 1 and 4 are used as daisy-chain
connections to other loudspeakers.
For wiring in parallel, connect the wire pair of the subsequent speaker to pins 1
and 4. When one input connector is removed, subsequent speakers will also be
disconnected. See Figure 8.
When all wiring has been completed to the connector, plug the connector into the
socket in the speaker's terminal cup. See Figure 9. Tighten all screws to eliminate
vibration.
