1.1. Information regarding the use of loudspeakers
Potential risk of personal injury
Never stand in the immediate vicinity of loudspeakers driven at a
high level. Professional loudspeaker systems are capable of
causing a sound pressure level detrimental to human health.
Seemingly non-critical sound levels (from approx. 95 dB SPL) can
cause hearing damage if people are exposed to it over a long
period.
In order to prevent accidents when deploying loudspeakers on the
ground or when flown, please take note of the following:
– When setting up the loudspeakers or loudspeaker stands,
make sure they are standing on a firm surface. If you place
several systems on top of one another, use straps to secure
them against movement.
– Only use accessories which have been tested and approved
by d&b for assembly and mobile deployment. Pay attention to
the correct application and maximum load capacity of the
accessories as detailed in our specific "Mounting instructions"
or in our "Flying system and Rigging manuals".
– Ensure that all additional hardware, fixings and fasteners used
for installation or mobile deployment are of an appropriate
size and load safety factor. Pay attention to the manufacturers'
instructions and to the relevant safety guidelines.
– Regularly check the loudspeaker housings and accessories for
visible signs of wear and tear, and replace them when
necessary.
– Regularly check all load bearing bolts in the mounting devices.
Potential risk of material damage
Loudspeakers produce a static magnetic field even if they are not
connected or are not in use. Therefore make sure when erecting
and transporting loudspeakers that they are nowhere near
equipment and objects which may be impaired or damaged by an
external magnetic field. Generally speaking, a distance of 0.5 m
(1.5 ft) from magnetic data carriers (floppy disks, audio and video
tapes, bank cards, etc.) is sufficient; a distance of more than 1 m
(3 ft) may be necessary with computer and video monitors.
1. Safety precautions
d&b 12S-SUB Manual (1.3 EN)4

2.1. Product description
The 12S-SUB is a compact high performance subwoofer for use
with d&b xS-Series loudspeakers. The cabinet houses a long
excursion 12” neodymium driver in a bass-reflex design.
The 12S-SUB frequency response extends from 45 Hz to
130/100 Hz.
The enclosure is constructed from marine plywood with an impact
resistant black paint finish. The front of the cabinet is protected by
a rigid metal grill backed by an acoustically transparent foam.
Four rubber feet prevent cabinet movement and protect the bottom
panel against scratching.
The cabinet is Ball Impact Resistant according to DIN 18032-3.
Rigging components
The 12S-SUB side panels are each equipped with a pair of M10
threads to accept the Z5412 Horizontal bracket 12S-SUB. The
threaded inserts are covered by dummy caps in cabinet color. The
caps must be removed before mounting any accessories.
Cabinet options
The weather resistant version (WR) is suitable for outdoor use
(IP34, vertical aiming up to 0°). The cabinets have an impact and
weather protected black PCP (Polyurea Cabinet Protection) finish.
2.2. Connections
The cabinet is fitted with a pair of NL4 connectors and a two pole
screw terminal block (ST). All four pins of both NL4 connectors are
wired in parallel. The cabinet uses the pin assignments 2+/2–. Pins
1+/1– are designated to full range cabinets.
Cabinets with the weather resistant option (WR) are equipped with
a fixed input cable (PG type, H07-RN-F, 2 x 2.5 mm2 (AWG 13),
standard length 5.5 m (18 ft).
Pin equivalents of the applicable connector options are listed in the
table below.
NL4 1+ 1– 2+ 2–
ST n.a. n.a. + –
PG n.a. n.a. Brown (+) Blue (–)
Fixed cable connection
The 12S-SUB loudspeaker is supplied with a cover plate [1] and a
rubber grommet feed through [2]. For indoor operation, these
items can be used to hide the connector panel, if required. For
unprotected outdoor operation, the connector panel must be
covered, i.e. both items must be used to achieve an IP degree of
protection of IP34.
To install the fixed cable connection, proceed as follows:
Tools required: Philips screw driver (#PH2).

1. Prepare the rubber grommet and the connection cable.
2. Remove the knockout opening in the cover plate and attach
the rubber grommet correspondingly.
3. Insert the connection cable through the rubber grommet and
connect the cable wires to the screw terminal.
Þ Observe the correct polarity!
4. Undo the four screws of the connector panel.
5. Push the cover plate towards the connector panel until it fits
into place.
6. Finally fix the cover plate together with the connector panel
using the four screws.
Fig. 4: Installing the fixed cable connection
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 5.
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.
