Operating modes
4-wire operation (standard wiring EP5 and NL4)
Connector wiring
(4-wire operation with EP5 connectors)
The MAX cabinet is driven by a 4-wire cable to allow the choice of
active or passive operation. The HF and LF drivers are each fed by their
own pair of pins and separate passive crossovers. Pin assignments 1/2
of the EP5 connectors (NL4: 1+/1–) connect the LF driver, pins 3/4
(2+/2–) connect the HF driver, as shown in the diagram opposite.
2-wire operation (NL4 only)

Fig. 2: MAX 4-wire operation NL4
For applications requiring dedicated passive use, the MAX cabinet’s
internal wiring can be configured for connection to pins 1+/1– of the
NL4 connectors allowing use of a 2-wire cable.
In the 2-wire/passive configuration both the LF and HF drivers are
connected to pins 1+/1– of the NL4 connector. Note that only the HF
driver wiring (white and white/red) differs from that used in the 4-wire
version.
The passive 2-wire configuration can also be used when the MAX
cabinet is combined with a d&b active subwoofer and driven through a
single 4-wire cable.
In the 2-wire configuration MAX can also be used with amplifiers from
other manufacturers. The output connector of the amplifier or signal
distribution box should feed the positive signal to pin 1+ and the
negative signal to pin 1– of the cabinet’s NL4 connector.
