SL-Series rigging components and arrays
The cabinets are mechanically connected using the rigging strands
on both sides of the cabinet front and a central strand at the rear
of the cabinet. All necessary rigging components are mounted on
the cabinet and fold out or slide out when needed.
A detailed description of the rigging components is given in the
respective rigging manuals.
2.2 Connections
The cabinets are fitted with NLT4 F/M connectors. All four pins of
both connectors are wired in parallel using the following pin
assignment:
▪ 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°, 1° or 2°. 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.
