NL4 connection with cover plate
The two NL4 connector sockets of the cabinet's connector panel
are located in a recess to allow the use of the cover plate [1]
together with NL4 cable connectors, as shown in the graphic
opposite.
Note: Neutrik NL4FC type connectors must be used for this
option.
The cover plate is equipped with two knockout openings to allow
daisy chaining of the loudspeaker.
To use the NL4 connection, proceed in the same manner as
described above in the section entitled Þ "Fixed cable connection"
on page 6.
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.
Operation with D6 or D12
Select the controller setup 10AArc or 10ALin for 10AL
loudspeakers.
Select the controller setup 10ADArc or 10ADLin for 10AL-D
loudspeakers.
Within the D12 amplifier they are available in "Dual Channel" or
"Mix TOP/SUB" mode. For combinations with active subwoofers
fed by a single 4-wire cable "Mix TOP/SUB" mode must be
selected.
Up to a total of three 10AL or 10AL-D loudspeakers can be driven
by each channel of the D6 or D12 amplifiers.
"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°, 2° or 4. Compared to
the "Arc" setup, the upper mid range is reduced to compensate for
the extended near field.
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
three.
