Safety precautions
Information regarding use of loudspeakers
WARNING! 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.
CAUTION! 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.
E0 Manual (3.2 EN) Safety precautions - 1

E0
Fig. 1: E0 loudspeaker
The E0 is a compact, coaxial 2-way loudspeaker fitted with a 5” LF
driver and 1” dome tweeter.
The E0 is housed in a cleverly shaped strong polyamide cabinet
containing magnetic shielding of the LF driver. A rigid metal grill
protects the front of the loudspeaker cabinet. Recessed into the rear is a
quad push connector and a self-locking ball joint with integrated
mounting arm that incorporates an M10 female thread. Along with a
selection of d&b rigging accessories the E0 can be deployed quickly and
easily in a variety of configurations.
Whilst the loudspeaker components are shielded against magnetic
radiation, we advise a minimum distance of 15 cm (0.5 ft) between the
E0 and susceptible equipment (e.g. PC and video monitors).
NOTICE: Only operate E0 loudspeakers with a correctly configured d&b
amplifier, otherwise there is a risk of damaging the loudspeaker
components.

Fig. 3: Wiring of the NL4 connectors
The E0 loudspeaker can be supplied with three connection options.
Push connector:
Two pairs of push connectors wired in parallel (cross-section up to
6 mm2 (AWG 10).
NL4 connector:
Two NL4 connectors wired in parallel using pins 1+/1–. Pins 2+/2– are
not connected – refer to the graphic opposite - Fig. 3.
Using one connector as the input, the second connector allows for direct
connection to additional loudspeakers.
Fixed cable (PG):
E0 loudspeakers with the weather resistant option (WR) are supplied
with a cable gland (screw thread) and are fitted with a 2 m/6.6 ft cable
(cable H-05-RR-F 2 x 0.75 mm2).
Dimensioning of the loudspeaker cable:
We recommend a loudspeaker cable with a minimum cross-section of
0.5 mm2. The minimum cross-section required for a single cabinet can
be calculated from:
crosssectionmm2=

length
of
cable

m


Where multiple E0 loudspeakers are connected in parallel the minimum
cross-section required is obtained by multiplying the above result by the
number of cabinets.

option (PG) are listed in the table below.

Operation with D6 or D12
Select the controller setup E0.
Within the D12 amplifier this is available in "Dual Channel" and "Mix
TOP/SUB" mode.
Up to a total of four E0 loudspeakers can be driven by each D6 or D12
amplifier channel.
Controller settings
For acoustic adjustment the functions CUT, HFA and CPL can be
selected.
CUT circuit
Set to CUT, a high pass filter with a 120 Hz cut off frequency is inserted
in the controller signal path. The E0 is now configured for use with d&b
active subwoofers.

Fig. 4: Frequency response correction of
HFA circuit
In HFA mode (High Frequency Attenuation), the HF response of the E0
system is rolled off. The HFA circuit 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.
CPL circuit
Fig. 5: Frequency response correction of
CPL circuit
The CPL (Coupling) circuit compensates for coupling effects between the
cabinets when building closely coupled arrays. CPL begins gradually at
1 kHz, with maximum attenuation below 250 Hz, providing a balanced
frequency response when E0 cabinets are used in arrays of two or
more. The function of the CPL circuit is shown in the diagram opposite
and can be set in dB attenuation values between –9 and 0.
Operation with E-PAC
Selecting E0 mode enables the E-PAC to drive up to two E0 cabinets.
LO IMP mode allows the E-PAC to drive a maximum of four E0 cabinets
with a 6 dB reduction of input level to the loudspeakers.
The CUT and HFA settings are available. The characteristics of the CUT
and HFA settings are explained in the previous section "Operation with
D6 or D12 - Controller settings".

Dispersion characteristics
Due to the coaxial driver design, the horizontal and vertical dispersion
characteristics of the E0 are identical. The diagram below shows
dispersion angle vs frequency plotted using lines of equal sound
pressure (isobars) at –6 dB and –12 dB.

E0 Accessories
Fig. 9: E0 with B2123 Fixing plate
Recessed into the rear is a self-locking ball joint with an integrated
mounting arm that incorporates an M10 female thread. The E0 rigging
accessories allow different mounting of the E0 loudspeaker as described
below:
- The E0 comes with the B2123 Fixing plate to allow mounting to walls
and ceilings or other surfaces.
- Single cabinets can be hung from a truss or bar using the E6532
Super Clamp together with the E6533 M10 adapter for Super
Clamp. The jaw of the Super Clamp can be adjusted to fit bars, or
any other supporting structures with diameters from 13 to 55 mm
(0.5" to 2.2").
- Alternatively, the Z5029 TV spigot together with the Z5012 Pipe
clamp can be used for tube diameters from 32 to 50 mm (1.25" to
2").
- The Z5035 M10 to 3/8" adapter enables the E0 to be mounted to a
microphone stand, whilst the Z5034 Stand adapter allows the E0 to
be mounted to a loudspeaker stand. The E0 is mounted horizontally
when using either a microphone or loudspeaker stand.
Safety instructions
[S]
WARNING! When attaching the accessories as listed above to the
mounting arm of the E0 loudspeaker, the spring washer
M10 must always be used.
When using the accessories as listed above, please refer
to the accessory specific mounting instructions.
Secondary safeties should always be provided and used
when flying or fixing loudspeaker loads overhead. In
case of the E0 loudspeaker there is a safety hook [S] at
the back of the loudspeaker to which a safety rope
should be attached.
Under no circumstances should the safety hook [S] be
used to support other loads.
