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.

d&b E6 Manual 1.1 en4

2.1. Product description
The E6 is a high performance multipurpose loudspeaker employing
an integrated 6.5"/1" exit coaxial driver design with neodymium
magnet and constant directivity horn loading. The horn with its
100° x 55° (hor. x vert.) dispersion pattern can easily be rotated
through 90° providing a 55° x 100° pattern without the use of
tools.
The E6 is a two-way design with a built-in passive crossover
network. Its frequency response extends from 85 Hz to 20 kHz.
The enclosure is injection molded 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 cabinet is protected by a rigid metal
grill backed by an acoustically transparent fabric.
The loudspeaker cabinet incorporates a handle and four M8
threaded inserts to connect to different rigging accessories like
Z5377 E6 Swivel bracket, Z5378 E6 Horizontal bracket or a
safety wire.
The connector panel of the E6 cabinet is recessed and tilted to
allow deployment as a stage monitor. With the panel on the right
hand side, the cabinet is oriented correctly.
Cabinet options
The special color (SC) version of the cabinet is available in all
colors of the RAL color table. It comes without handle. The
respective opening of the cabinet is covered by a plate in cabinet
color. The connector type is NL4.
The weather resistant (WR) version is available in black only. It
also comes without handle. 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 cabinet is 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.
Application Setup Cabinets per
channel
E6 E6 5
For applicable d&b amplifiers, the controller setup is 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.
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 E6 mode enables the E-PAC to drive up to three E6
loudspeakers. LO IMP mode configures the E-PAC to drive a
maximum of five E6 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.
2.4. Dispersion characteristics

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

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
above the ground.
There are no tools required as the grill is attached to the baffle by
magnets. It is secured by an additional safety wire.
The grill can be accessed through an opening in the top handle of
the cabinet.
1. Disconnect the loudspeaker.
2. Remove the grill by reaching with one hand into the opening
underneath the top handle and pushing against the backside
of the grill.
3. Take the horn at its outer edges and turn it until it snaps into
the desired direction.
4. Relocate and fix the front grill.
ÞMake sure the safety wire slips into the recess between
baffle and cabinet body.
