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.

2.1. Product description
The E12 and E12-D are high performance multipurpose
loudspeakers employing an integrated 12"/1.3" exit coaxial driver
design with neodymium magnet and constant directivity horn
loading. It is available in two different dispersion versions, the E12
providing a 80° x 50° dispersion pattern (hor. x vert.), the E12-D
a wider 110° x 50° pattern. Both horns can easily be rotated
through 90° without the use of tools, providing 50° x 80° or 50°
x 110° dispersion patterns.
The E12 is a two-way design with a built-in passive crossover
network. Its frequency response extends from 50 Hz to 18 kHz.
The enclosures are constructed from polyurethane integral hard
foam with an impact resistant paint finish. The cabinet shape allows
use either in a vertical or horizontal orientation as well as
deployment as a stage monitor. The front of the loudspeaker
cabinets are protected by a rigid metal grill backed by an
acoustically transparent foam.
The loudspeaker cabinets incorporate a pair of handles, a pole
mount socket and six M10 threaded inserts to connect to different
rigging accessories like Z5352 Flying bracket E12, Z5020 Flying
adapter 02, Z5025 Flying adapter 03or a Z5353 Horizontal
bracket E12. An additional M10 thread in the rear panel can be
used to connect a safety wire.
Cabinet options
The special color (SC) version of the cabinet is available in all
colors of the RAL color table. It comes without high stand flange
and handles. The respective openings of the cabinet are covered
by plates in cabinet color. The connector type is NL4.
The weather resistant (WR) version is available in black only. It
also comes without high stand flange and handles. It is equipped
with a fixed input cable (PG: 5.5 m / 18 ft, type H07-RN-F
2 x 2.5 mm2 / AWG 13).
2.2. Connections
The cabinets are fitted with NLT4 F/M connectors. All four pins of
both connectors are wired in parallel. The cabinet uses the pin
assignments 1+/1–. Pins 2+/2– are designated to actively driven
subwoofers. Using one connector as the input, the second
connector allows for direct connection to a second cabinet.

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.
Applicable d&b amplifiers:
D80/D20/D12/D6/10D/30D.
Standard operation
Application Setup Cabinets per
channel
E12 E12 2
E12-D E12-D 2
For applicable d&b amplifiers, the controller setups are available
in Dual Channel and/or Mix TOP/SUB mode. For combinations
with active subwoofers fed by a single 4-wire cable Mix TOP/SUB
mode must be selected.
Passive operation
Application Setup Combination per
channel
E12
with E15X-SUB
E12-X 1
E12-D
with E15X-SUB
E12-DX 1
In Dual Channel mode, the "X" setup can be selected to drive the
cabinet in combination with the E15X subwoofer on the same
channel.
The setup provides a dedicated correction for the combined
frequency response of the system.
d&b E12/E12-D Manual 2.1 en6

2.3.1. Controller settings
For acoustic adjustment the functions CUT, HFA and CPL can be
selected.
CUT mode
Set to CUT, the low frequency level is reduced. The cabinet is now
configured for use with actively driven d&b subwoofers.
HFA mode
In HFA mode (High Frequency Attenuation), the HF response of the
system is rolled off. HFA provides a natural, balanced frequency
response when a cabinet 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 function
The CPL (Coupling) function compensates for coupling effects
between the cabinet and close boundary surfaces or when the
cabinet is used as a stage monitor. CPL begins gradually around
1 kHz, with the maximum attenuation below 250 Hz. To achieve a
balanced frequency response, the CPL function 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.
2.3.2. Operation with E-PAC
Selecting E12 or E12-D mode enables the E-PAC to drive one E12
or E12-D loudspeaker. LO IMP mode configures the E-PAC to drive
a maximum of two E12 or E12-D loudspeakers with a 6 dB
reduction in input level to the loudspeakers.
For acoustic adjustment the CUT and HFA modes are available.
The characteristics are described in the previous section.

Altering the HF horn dispersion
The HF horn can be rotated through 90° within the coaxial driver
assembly.
CAUTION!
Potential risk of personal injury due to falling
objects.
– Set the correct horn orientation before suspending the cabinet.
– Do not remove the front grill while the cabinet is mounted or
flown above the ground.
Tools required: screw driver or an appropriate coin.
1. Disconnect the loudspeaker.
2. Undo the quick locks at the top and bottom of the front grill
and remove the grill.
3. Pick the horn at its outer edges and turn it until it snaps into the
desired orientation.
4. Relocate and fix the front grill.
ÞMake sure both quick locks of the front grill are locked
correctly before using the loudspeaker.
