2.2. Connections
The cabinet is fitted with a single NLT4 F connector. It uses the pin
assignments 1+/1– for the front drivers. Pins 2+/2– drive the rear
driver.
The cabinets can be supplied with EP5 or NL8 connectors as an
option.
Pin equivalents of the connector options are listed in the table

d&b SenseDrive
The SenseDrive feature within D12 amplifiers enables electrical
compensation for the properties of the loudspeaker cable used.
SenseDrive requires an additional sense wire. SenseDrive is
therefore only available with EP5 connectors and 5-wire cabling
for applicable loudspeakers.
Note: To enable SenseDrive for the front drivers, the
loudspeaker cabinet has to be connected to output A.
d&b LoadMatch
Starting with the D80 amplifier platform, the LoadMatch function
enables the amplifier to electrically compensate for the properties
of the loudspeaker cable used without the need for an additional
sense wire. For applicable loudspeakers, LoadMatch is therefore
independent of the connector type used.
2.3. Operation
NOTICE!
Only operate d&b loudspeakers with a correctly configured d&b
amplifier, otherwise there is a risk of damaging the loudspeaker
components.
