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–. Pins 2+/2– are designated to actively driven
subwoofers. Using one connector as the input, the second
connector allows for direct connection to a second cabinet.
The cabinets can be supplied with 2 x NL4 M connectors as an
option.
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.
