2.2. Connections
The cabinets are fitted with NLT4 F/M connectors. All four pins of
both connectors are wired in parallel. The cabinet uses the pin
assignments 1+/1– for the LF drivers. Pins 2+/2– are designated
to MF/HF section. Using one connector as the input, the second
connector allows for direct connection to a second cabinet.
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 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.
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, at least one of the cabinets has
to be connected to output A of the D12 amplifier.
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.
Applicable d&b amplifiers:
D80/D12/30D.
