d&b Y8 - Manual (Page 6)

2.2. Connections
The cabinets are fitted with a pair of NLT4 F/M connectors. All
four pins of both connectors are wired in parallel. The Y8 and Y12
loudspeakers use the pin assignments 1+/1–. Pins 2+/2– are
designated to actively driven subwoofers. Using the male
connector as the input, the female connector allows for direct
connection to a second cabinet.
The cabinets can be supplied with NL4 M or EP5 connectors as an
option.
Pin equivalents of the connector options are listed in the table
below.

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.
The applicable amplifiers provide two setups ("Arc" or "Line") for
the Y8 and Y12 loudspeakers. These are available in Dual
Channel or Mix TOP/SUB mode.
Selecting the respective Y8 or Y12 setup enables up to two Y8 or
Y12 cabinets to be driven by the respective amplifier channel.
Arc and Line setups
The selection of Arc or Line depends on the curvature of the array.
Both setups may be used within one array.
The Arc setup is intended for line array loudspeakers when used in
curved array sections.
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 mid/high range is reduced to compensate for the
extended nearfield.
The transition from Line to Arc configuration within the array is
made according to the splay progression but may allow for certain
deviations due to the wiring of the cabinets in groups of up to two.
