NLT4 F/M, NL4 M and EP5 connector wiring

2.2 Connections

The cabinet is fitted NLT4 F/M connectors. All four pins of both
connectors are wired in parallel. The V-SUB uses the pin
assignments 2+/2–. Pins 1+/1– are designated to the V8 or V12
loudspeakers. Using one as the input, the second connector allows
for direct connection to a second cabinet.
The cabinet can be supplied with NL4 M or EP5 connectors as an
option.
Pin equivalents of the connector options are listed in the table
below.

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.

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/D40/D20/D12.
Amplifier output mode(s): Dual Channel or Mix TOP/SUB
Application Setup
V-SUB V-SUB
V-SUB AP
* When using the D40/40D amplifiers and maximum output is
required, it is recommended to only drive one V-SUB per
amplifier channel. Two V-SUBs in parallel per channel are
possible, but this is only recommended for applications with
reduced output demand.
