2.2 Connections

The cabinets are fitted with a single NLT4 F connector using the

following pin assignments:

▪ Pins 1+/1– feeding the forward LF drivers.

▪ Pins 2+/2– are connected to the passive crossover networks

feeding the side firing LF drivers and the MF/HF driver sections.

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.

Line and Arc setups

The selection of "Line" or "Arc" depends on the curvature of the

array. Both setups may be used within one array.

The "Line" setup is used for long throw array sections with three or

more consecutive splay settings of 0° or 1°. Compared to the

"Arc" setup, the "Line" setup considers the different cabinet

interaction effects between straight and curved section of an array.

The Arc setup is intended for line array loudspeakers when used in

curved array sections.

AP setup

In connection with d&b ArrayProcessing (AP), the AP setup

contains the AP data that is generated by the ArrayCalc simulation

software and transferred to the applicable amplifiers via the d&b

Remote network (OCA/AES70) using R1.

As soon as the data has been sent to the amplifiers, the AP setup is

automatically activated.
