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.

E18-SUB
Fig. 1: E18-SUB loudspeaker
The E18-SUB is a compact, very low tuned bass-reflex design employing
a single 18" driver.
The E18-SUB cabinet is constructed from marine plywood and has an
impact resistant paint finish. The front of the loudspeaker cabinet is fitted
with a rigid metal grill covered with a replaceable acoustically
transparent foam and fitted with catches at the top and bottom to
secure an optional transport lid (E7908). The cabinet incorporates a
pair of steel handles and on the rear panel four heavy duty wheels. An
M20 threaded flange in the top panel accepts the Z5013 Loudspeaker
stand for the deployment of full range cabinets.
NOTICE: Only operate E18-SUB subwoofers with a correctly configured d&b
amplifier, otherwise there is a risk of damaging the loudspeaker
components.

Fig. 2: Connector wiring
The E18-SUB cabinet is fitted with a pair of EP5 connectors. All pins of
both connectors are wired in parallel.
The E18-SUB uses the pin assignments 3/4 and 5 (Pin 5: SenseDrive -
D12 only and in conjunction with 5-wire cables).
Pins 1/2 are designated to d&b full range systems.
Using one connector as the input, the second connector allows for direct
connection to additional cabinets.
The E18-SUB can be supplied with NL4 output connectors as an option
using the pin assignment 2+/2–. Pins 1+/1– are designated to d&b full
range systems. The D12 SenseDrive function is not available with NL4
connectors.
Pin equivalents of EP5 and NL4 connectors are listed in the table below.

Operation with D6 or D12
Select the controller setup E18-SUB.
Within the D12 amplifier this is available in "Dual Channel" and "Mix
TOP/SUB" mode.
Up to a total of two E18-SUB loudspeakers can be driven by each D6
or D12 amplifier channel.
In applications with low continuous levels and low ambient temperatures
up to three cabinets can be connected to a D12 channel.
When the D12 is operated in "Mix TOP/SUB" mode, the E18-SUB
cabinet and a respective full range cabinet can be linked together
locally and fed by a single 4-wire cable from either amplifier output
connector.
To apply SenseDrive for the subwoofer, EP5 connectors and 5-wire
cables have to be used. When operated in "Mix TOP/SUB" mode,
subwoofers have to be fed from the output B connector of the D12
amplifier.
Operation with E-PAC
Fig. 3: E-PAC version 2 configuration for
E18-SUB
To drive E18-SUB cabinets, the E-PAC has to be configured to E18-SUB
mode.
For an E-PAC version 2, the configuration is selected by setting the
appropriate DIP switches on the rear panel. DIP switches 1 and 2 (CUT
and HFA) are not functional with the configuration E18-SUB .
For an E-PAC version 3, the configuration is set via the encoder in
conjunction with an LCD.
The E-PAC can drive a single E18-SUB cabinet.
Operation with P1200A
Fig. 4: Controls on E18-SUB
controller module
Up to two E18-SUB cabinets can be driven by each P1200A power
amplifier channel fitted with an E18-SUB controller module. Fitting one
E18-SUB and one TOP controller module allows a single mainframe to
drive two E18-SUB and two mid/high cabinets. All cabinets can be
linked together locally and fed by a single 4-wire cable from either
mainframe output connector.
160 Hz switch
If the 160 Hz switch is selected, the upper operating frequency of the
system is increased from 110 Hz to 160 Hz.
