SL-Series rigging components and arrays
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 SL-Series rigging components is given
in the SL-Series Rigging manual.

2.2. Connections

The cabinets are fitted with a single NLT4 F connector using the pin
assignment 1+/1– for the front drivers and pins 2+/2– for the
rear driver.
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.

2.3. Operation

Amplifier output mode(s): 2-Way Active
Application Setup
SL-SUB SL-SUB
SL-SUB AP
SL-GSUB SL-SUB
In its standard mode the SL-SUB/SL-GSUB can be used as
subwoofer for applicable d&b loudspeaker systems operated in
CUT mode. The two channels of the system are tuned to create a
cardioid dispersion pattern thus providing maximum rejection to the
rear. It can be used in flown or stacked combinations with a
minimum distance of 60 cm (2 ft) between adjacent columns of
cabinets.
AP setup
In connection with d&b ArrayProcessing (AP), the AP setup
contains the AP data that are generated in 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 have been sent to the amplifiers, the AP setup
will be automatically activated.

2.3.1. Controller settings

INFRA mode
With the INFRA mode selected, the upper operating frequency of
the system is reduced from 90 Hz to 70 Hz. The SL-SUB/SL-GSUB
can now be used to supplement applicable d&b loudspeaker
systems operated in full range mode.
