5.2.5. Loudspeaker wiring
The passive full range/TOP systems and passive subwoofers use pins 1
and 2 of the EP5 connector (1+ and 1– of the NL4 connector).
Actively driven subwoofers use pins 3/4 and pin 5 of the EP5
connectors (2+ and 2– of the NL4 connector).
These pin assignments allow full range cabinets and subwoofers to be
linked together and connected to the amplifier in mixed configuration
(Mix-TOP/SUB) using a single 4 or 5-wire cable. SenseDrive is only
available when using EP5 connectors and 5-wire cables.
Pin equivalents of EP5, NL4 and NL8 connector in relation to the output
modes of the D12 amplifier are listed in the table below.
