2.2. Connections
The cabinet is fitted with NLT4 F/M connectors. All four pins of
both connectors are wired in parallel. It uses the pin assignments
2+/2–. Pins 1+/1– are designated to TOP cabinets. Using one as
the input, the second connector allows for direct connection to a
second cabinet.
Pin equivalents of the connector options are listed in the table

d&b LoadMatch
With the d&b four channel 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: When the D12 is operated in "Mix TOP/SUB mode",
the SenseDrive function is only available at the output B
connector.
