Fig. 3: Connector wiring
The Ti-SUB cabinet is fitted with a pair of NL4 connectors. All pins of
both connectors are wired in parallel. The Ti-SUB uses the pin
assignments 2+/2–. Pins 1+/1– are designated to d&b full range
systems. Using the male connector as the input, the female connector
allows for direct connection to additional loudspeakers.
The weather resistant (WR) version of the Ti-SUB is equipped with a
fixed input cable (5 m/16.4 ft, type H-07-RN-F 2 x 2.5 mm
2 /AWG 13).
Pin equivalents of NL4 connectors and the fixed cable option are listed
in the table below.

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 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.
Operation with D6 or D12
