Fig. 3: Connector wiring
The
Qi-SUB is supplied with two NL4 connectors. All pins of both
connectors are wired in parallel. The Qi-SUB uses the pin assignments
2+/2–. Pins 1+/1– are designated to Qi-Series full range systems.
Using one connector as the input, the second connector allows for direct
connection to additional loudspeakers.
In case of the
QiCSA-SUB the front grill of the cabinet baffle is fitted
with a single NL4 connector located at the bottom left hand side of the
grill.
Installation loudspeakers with the weather resistant option are supplied
with a fixed cable (PG).

In permanent installations SenseDrive can also be applied to cabinets
with NL4 connectors or fixed cable option (PG). The connection of the
negative signal wire (EP5 pin 4 of the respective D12 output) to the
SenseDrive wire (EP5 pin 5 of respective D12 output) is made in a
junction box close to the loudspeaker cabinet. For an uncompromising
SenseDrive performance the connection should be done not more than
3 m (10 ft) away from the loudspeaker.
