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 noncritical 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.

Fig. 1: E12 loudspeaker
NOTICE:
E12, E12-D
The E12 is a high performance multipurpose loudspeaker 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 are
easily rotatable 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 above 17 kHz.
E12 and E12-D have identical enclosures constructed from
polyurethane integral hard foam with an impact and weather resistant
black 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 cabinet is protected by a rigid metal grill
in front of an acoustically transparent foam. The grill can easily be
removed without tools to modify the horn orientation.
The cabinets incorporate a pair of handles, a recessed pole mount
socket and six M10 threaded inserts to connect to different rigging
accessories like Z5352 E12 Flying bracket, Z5354 E8/E12 Flying
adapter, Z5020 Flying adapter 02, Z5025 Flying adapter 03 or Z5353
E12 Horizontal bracket. An additional M10 thread in the rear panel
can be used to connect a safety wire.
Only operate E12 loudspeakers with a correctly configured d&b
amplifier, otherwise there is a risk of damage to the loudspeaker
components.
Fig. 2: E12, E12-D SC/WR versions top and
bottom view
Please note that E12 and E12-D require different controller setups and
therefore cannot be wired in parallel.
E12, E12-D cabinet options
The special color (SC) version of the cabinet is available in all colors of
the RAL color table. It comes without hi 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 hi stand flange and handles. It is equipped with a fixed
input cable (5 m / 16.4 ft, type H-07-RN-F 2 x 2.5 mm2/AWG 13).
E12, E12-D Manual (1.2 EN) Page 4 of 10
Connections
The E12 cabinet is fitted with a pair of EP5 connectors. All five pins of
both connectors are wired in parallel. The E12 uses the pin assignments
1/2. Pins 3/4 and 5 are designated to active subwoofers, where pin 5
is used for SenseDrive (only available when using a D12 amplifier and
5-wire cabling). Using the male connector as the input, the female
connector allows for direct connection to additional loudspeakers.
The E12 can be supplied with NL4 connectors as an option.

Operation with D6 or D12
Select the controller setups E12 or E12-D.
Within the D12 amplifier they are available in "Dual Channel" and
"Mix TOP/SUB" mode. For combinations with active subwoofers fed by
a single 4/5-wire cable "Mix TOP/SUB" mode must be selected.
D6 and D12 provide the additional setups E12-X and E12-DX to be
selected when E12 or E12-D cabinets are used in combination with
passive E15X-SUB loudspeakers on the same channel. They provide a
dedicated correction for the combined frequency response of these
systems.
Selecting the E12 (E12-D) setup enables up to a total of two E12 (E12D) loudspeakers to be driven by the respective D12 or D6 channel.
Selecting the E12-X (E12-DX) setup enables a combination of one E12
(E12-D) and one E15X-SUB to be driven by the respective D12 or D6
channel.
In applications with low continuous levels and low ambient
temperatures up to three cabinets can be connected to a D12 channel.
Controller settings
For acoustic adjustment the functions CUT, HFA and CPL can be
selected.
CUT circuit
Set to CUT, the E12 low frequency level is reduced. The E12 is now
configured for use with E15X-SUB in active mode or other d&b active
subwoofers.

Fig. 4: Frequency response correction of
HFA circuit
HFA circuit
In HFA mode (High Frequency Attenuation), the HF response of the E12
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
The CPL (Coupling) circuit compensates for coupling effects when
building closely coupled arrays or when the cabinet is used as a stage
monitor. CPL begins gradually at 1 kHz, with maximum attenuation
below 250 Hz, providing a balanced frequency response when E12
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, or a positive CPL value which
creates an adjustable low frequency boost around 65 Hz (0 to +5 dB).
Fig. 5: Frequency response correction of
CPL circuit
Operation with E-PAC
Selecting E12 or E12-D mode enables the E-PAC to drive one E12
loudspeaker. LO IMP mode configures the E-PAC to drive a maximum
of two E12 loudspeakers with a 6 dB reduction in input level to the
loudspeakers.
For acoustic adjustment the functions CUT and HFA can be selected.
The characteristics of the CUT and HFA settings are explained in the
previous section "Operation with D6 or D12".

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.
- Undo the quick locks at the top and bottom of the front grill and
remove the grill
- Pick the horn at its outer edges and turn it until it snaps into the
desired orientation.
- Relocate and fix the front grill.
CAUTION: Make sure both quick locks of the front grill are locked
correctly before using the loudspeaker.
