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 4S/5S Manual (1.1 EN)4
2.1. Product description
The 4S and 5S cabinets are high performance 2-way loudspeakers
for a wide range of installed sound applications. Both models are
light-weight passive designs using neodymium drivers and
coaxially mounted, wide dispersion dome tweeters.
The 4S employs a 4” driver in an ultra-compact, sealed enclosure.
Its frequency response extends from 130 Hz to 20 kHz.
The 5S comprises a 5” low driver in a bass-reflex enclosure
covering the range from 80 Hz to 20 kHz.
Both systems can be used stand-alone or supplemented by
different subwoofers of the xS-Series.
The enclosures are injection molded with an impact resistant black
paint finish. The fronts of the loudspeaker cabinets are protected
by a rigid metal grill backed by an acoustically transparent foam.
The 4S and 5S rear panels incorporate two M8 threaded inserts to
accept the Z5401 Wall mount S. Using the M10 socket of its ball
joint adapter, the loudspeakers can be connected to different d&b
mounting accessories such as:
– Z5029 TV spigot,
– Z5034 Stand adapter,
– E6532 Super Clamp,
– Z5035 M10 to 3/8" adapter.
Intended use
Both cabinets are weather protected and suitable for outdoor use.
For unprotected outdoor operation the screw terminals must be
used for connection and the cover panels to hide the connector
panel (IP34, vertical aiming from +15° to –45°). A detailed
description of how to apply the fixed cable connection is given in
the following section (Þ Chapter 2.2. "Connections"
on page 6).
For this purpose the 4S cabinet must be installed with the M8
inserts located at the top of the cabinet's rear panel.

2.2. Connections
The cabinets are fitted with a pair of NL4 connectors and a two
pole screw terminal block (ST - cross-section up to 4 mm2/
AWG 11). All four pins of both NL4 connectors are wired in
parallel. The cabinets use the pin assignments 1+/1–. Pins 2+/2–
are designated to active subwoofers.
Pin equivalents of the applicable connector options are listed in the
table below.
NL4 1+ 1– 2+ 2–
ST + – n.a. n.a.
Fixed cable connection
The 4S and 5S loudspeakers are each 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:
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. Push the cover plate towards the connector panel until the
two spigots of the cover plate are in line with the center holes
of the two NL4 connectors.
5. Finally push the cover plate towards the cabinet until it
completely fits into the recess of the connector panel.

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 4S for 4S loudspeakers.
Select the controller setup 5S for 5S 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 four 4S or 5S loudspeakers can be driven by each
channel of the D6 or D12 amplifiers.
2.3.1. Controller settings
For acoustic adjustment the functions CUT, HFA and CPL can be
selected.
CUT circuit
Set to CUT, the cabinet low frequency level is reduced. The
cabinets are now configured for use with d&b active subwoofers.
HFA circuit
In HFA mode (High Frequency Attenuation), the HF response of the
system is rolled off. HFA provides a natural, balanced frequency
response when a unit is placed close to listeners in near field or
delay use.
High Frequency Attenuation begins gradually at 1 kHz, dropping
by approximately 3 dB at 10 kHz. This roll off mimics the decline
in frequency response experienced when listening to a system from
a distance in a typically reverberant room or auditorium.

d&b 4S/5S Manual (1.1 EN) 7
CPL circuit
The CPL (Coupling) circuit compensates for coupling effects
between the cabinets when building closely coupled arrays. CPL
begins gradually around 1 kHz, with the maximum attenuation
below 200 Hz. To achieve a balanced frequency response, the
CPL circuit can be set to dB attenuation values between 0 and –9.
Positive CPL values create an adjustable low frequency boost (0 to
+5 dB) and can be set when the system is used in full range mode
without subwoofers.

single cabinet plotted using lines of equal sound pressure (isobars)
at –6 dB and –12 dB.
