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 E4/E5 Manual 1.4 en4

2.1 Product description
The E4 and E5 cabinets are light-weight 2-way passive
loudspeakers using coaxially mounted, wide dispersion dome
tweeters. The coaxial design offers a symmetrical dispersion
pattern in the horizontal and vertical plane while the cabinets may
be mounted in either attitude.
The E4 employs a 4” neodymium LF driver in an ultra-compact,
sealed enclosure. Its frequency response extends from 130 Hz to
20 kHz.
The E5 employs a 5” ferrite LF driver in a bass-reflex enclosure
covering the range from 85 Hz to 20 kHz.
Both systems can be used stand-alone or supplemented by
different E-Series subwoofers.
The enclosures are injection molded with an impact resistant black
paint finish. The fronts of the loudspeaker cabinets are protected
by a rigid metal grill.
CAUTION!
No load suspension device
Under no circumstances should the safety hook [S] be used to
support other loads.
The E4 and E5 rear panels incorporate a M10 threaded insert to
accept the Z5356 E4/E5 Ball joint adapter.
In addition, a safety hook [S] is integrated in the rear panel to
allow the attachment of a secondary safety wire.
2.2 Connections
The cabinets are fitted with a pair of NL4 connectors and a two
pole push terminal block (PT - cross-section up to 6 mm2/
AWG 10). All four pins of both NL4 connectors are wired in
parallel. The cabinets use the pin assignments 1+/1–. Pins 2+/2–
are designated to active subwoofers.
Pin equivalents of the applicable connector options are listed in the
table below.

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
E4 E4 4
E5 E5 4
Within applicable d&b amplifiers, the controller setups are
available in Dual Channel 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 circuit
Set to CUT, the cabinet low frequency level is reduced. The
cabinets are now configured for use with d&b active subwoofers.
HFA circuit
In HFA mode (High Frequency Attenuation), the HF response of the
system is rolled off. HFA 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
between the cabinets when building closely coupled arrays. CPL
begins gradually around 1 kHz, with the maximum attenuation
below 200 Hz. To achieve a balanced frequency response, the
CPL circuit 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.
