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: E6 loudspeaker

E6

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 E6 enclosure is injection-molded from polyamide 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 fabric. The grill can easily be
removed without tools to modify the horn orientation.

The cabinet incorporates a handle and four M8 threaded inserts to
connect to different rigging accessories like Z5377 E6 Flying 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.

NOTICE:

Only operate E6 loudspeakers with a correctly configured d&b
amplifier, otherwise there is a risk of damaging the loudspeaker
components.

E6 cabinet options

The special color (SC) version of the cabinet is available in all colors of
the RAL color table. It comes without the 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 the handle. 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).

The E6 cabinet is fitted with a pair of EP5 connectors. All five pins of
both connectors are wired in parallel. The E6 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 5­wire cabling). Using the male connector as the input, the female
connector allows for direct connection to additional loudspeakers.

The E6 can be supplied with NL4 connectors as an option.

Operation with D6 or D12

Select the controller setup E6.

On the D12 amplifier it is 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.

Up to a total of four E6 loudspeakers can be driven by each channel of
the D6 or D12 amplifiers.

Controller settings

For acoustic adjustment the functions CUT, HFA and CPL can be
selected.

CUT circuit

Set to CUT, the E6 low frequency level is reduced. The E6 is now
configured for use with E12X-SUB or E15X-SUB in active mode or other
d&b active subwoofers.

HFA circuit

In HFA mode (High Frequency Attenuation), the HF response of the E6
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.

HFA circuit

E6 Manual, (1.1 EN) Page 5 of 10

Fig. 6: Frequency response correction of
CPL circuit

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 E6
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).

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 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 - Controller settings".

Altering the HF horn dispersion

The HF horn can be rotated through 90° within the coaxial driver
assembly. 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.

- Remove the grill.

- Take the horn at its outer edges and turn it until it snaps into the
desired direction.

- Relocate and fix the front grill.
Make sure the safety wire slips into the recess between baffle and
cabinet body.
