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 ALi60/ALi90 Manual 1.1 en4

2.1 Product description
The ALi60 and ALi90 are augmented array loudspeakers for
medium scale sound reinforcement applications providing a 60°
and 90° horizontal dispersion respectively.
Both loudspeakers are passive 2-way designs. They house 2 x 10"
neodymium LF drivers, one 1.4" exit HF compression driver with a
3" diaphragm mounted to a dedicated wave shaping device and a
passive crossover network. The wave segments of each cabinet
couple without gaps and sum up coherently.
Splay angles between adjacent cabinets can be set in the range
from 20° to 40° in 5° increments resulting in a total coverage of
50° up to 70° for two cabinets, with a maximum total coverage of
150° per array.
All components are arranged symmetrically around the center axis
of the cabinet to produce a perfectly symmetrical dispersion
pattern. This setup allows for a smooth crossover design with a well
defined overlap of adjacent frequency bands resulting in a very
consistent and accurate horizontal dispersion.
Due to the bipolar arrangement of the LF drivers, broadband
horizontal directivity control of 60°/90° is maintained down to
550 Hz/370 Hz respectively. The frequency response extends
from 60 Hz to 18 kHz.
The cabinets are constructed from marine plywood with an impact
resistant black paint finish. The front of the loudspeaker cabinet is
protected by a rigid metal grill backed by an acoustically
transparent fabric.
Three M10 threaded inserts are incorporated in one side panel to
allow the secure attachment of a dedicated flying adapter.
A-Series rigging components
When the d&b Z5455 AL Flying frame is used, up to four
loudspeaker modules can be flown in vertical columns producing a
60° or 90° constant directivity dispersion pattern in the horizontal
plane.
ALi60 and ALi90 can also be deployed as a horizontal cluster of
maximum four cabinets using the d&b Z5456 AL Flying adapter.
The d&b Z5458 AL Base plate allows ground stack setups of up to
three TOP cabinets, either as pure TOP ground stacks or placed on
top of applicable d&b subwoofers, such as the Vi-SUB or Vi-GSUB.

2.2 Connections
NOTICE!
Risk of damage to the system components!
Different pin assignment on the loudspeaker and amplifier.
Þ Please refer to the corresponding amplifier manual.
The cabinets are fitted with a 4-pole Phoenix connector socket
(Type: DFK PC 4/4 GF) using the pin assignment 1:+, 2:–, 3:+,
4:–. Pins 1/3 and 2/4 are linked. A corresponding Phoenix plug
(Type: SPC 5/4) is enclosed with the cabinet.
Using pin 1/2 as the input, pin 3/4 allows for direct connection to
a second cabinet.
Phoenix specifications and recommendations
The cabinet comes with a Phoenix plug (Type: SPC 5/4 Push-in
spring connector) which is already connected to the corresponding
Phoenix socket of the cabinet.
The plug allows for direct wire connection without any tools
depending on the cross section and conductor structure.
Technical specifications

Ferrule without plastic sleeve
d&b LoadMatch
With the d&b four channel amplifier platform, the LoadMatch
function enables the amplifier to electrically compensate for the
properties of the loudspeaker cable used without the need for an
additional sense wire. For applicable loudspeakers, LoadMatch is
therefore independent of the connector type used.
WR option (Weather Resistance)
A number of d&b loudspeakers are available in special options
suitable for different types of installed applications and
environmental conditions. The following options are available for
the ALi60/ALi90 loudspeaker:
▪ Weather resistant (WR): This option is suitable for outdoor use.
The cabinets have an impact and weather protected black PCP
(Polyurea Cabinet Protection) finish.
▪ Special version stadium (SVS): This option is suitable for outdoor
use, especially in stadiums. The cabinets are mechanically
supported by metal brackets which are specifically designed for
the respective application.
▪ Sea water resistant (SWR): This option is suitable for outdoor
use, especially in wet and acid or salty environments.
Connector wiring
d&b ALi60/ALi90 Manual 1.1 en6

WR cabinets are equipped with a recessed connector panel
including 4-pole Phoenix connector socket (Type: DFK PC 4/4
GF). A cover plate which accepts single or dual PG cable glands
(Type PG13.5 for cable diameters from 6 - 12 mm) is enclosed.
NOTICE!
The WR option enables operation of loudspeakers in changing
ambient conditions, however it is not intended to enable
permanent, unprotected operation of loudspeakers outdoors.
▪ Provide an additional cover over the loudspeakers.
▪ Aim the cabinets either horizontally or with a downward tilt.
To install the fixed connection cable, please proceed as follows:
Tools required: Screw driver (#T20).
Note: Observe the wiring diagram of the Phoenix plug and
Phoenix connector socket.
1. Insert the connection cable through the PG screwing and
connect the Phoenix plug to the Phoenix connector socket.
2. Push the cover plate towards the connector panel until it fits
into place.
3. Fix the cover plate to the connector panel using the four
countersunk screws.

PS setup
The PS setup (Point Source) provides dedicated signal processing
when ALi60/ALi90 cabinets are used in stand-alone applications.
Out/In setups (MDC)
The MDC (Midrange Directivity Control) function compensates for
constriction and uneveness (mid-range lobing) caused by the size
and geometry of an array within the 200 Hz to 2 kHz frequency
range in arrays of three or four loudspeakers.
MDC provides even distribution of the lower-mid frequency range,
matching the high frequency dispersion set through typical array
configurations, independent of the splay angle settings.
MDC uses two setups:
Out for 'outer' cabinets and In for 'inner' cabinets.
For two loudspeakers, the Out setup is recommended.
For three or four loudspeakers the Out setup is used for the outer
two cabinets of an array, while the In setup is used for the inner
one or two cabinets.
Two loudspeakers of the same type (ALi60 or ALi90) can be linked
and then be driven by one amplifier channel.
Note: For mixed arrays consisting of ALi60 and ALi90
cabinets, observe the dedicated setup for each loudspeaker
type and the required wiring Þ required amplifier channels.
AP setup
For vertical arrays consisting of a minimum of three cabinets, the
AP setup can be used.
The AP setup contains the AP data that is generated by the
ArrayCalc simulation software and transferred to the applicable
amplifiers via the d&b Remote network (OCA/AES70) using R1.
As soon as the data has been sent to the amplifiers, the AP setup is
automatically activated.
d&b ALi60/ALi90 Manual 1.1 en8

2.3.1 Controller settings
Depending on the loudspeaker setup selected, the CUT, HFA, CPL
and HFC functions are available for acoustic adjustment.
CUT mode
Set to CUT, a high pass filter with a 95 Hz cut off frequency is
inserted in the controller signal path. The ALi60/ALi90 are now
configured for use with actively driven d&b Vi-SUB or Vi-GSUB
subwoofers.
HFA mode (PS setup only)
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. CPL begins
gradually around 1 kHz, with the maximum attenuation below
400 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) at around 65 Hz and can be set when the system is used in
full range mode without subwoofers.
HFC function
Selecting the HFC (High Frequency Compensation) function
compensates for loss of high frequency energy due to absorption
in air when loudspeakers are used to cover far field listening
positions.
The HFC function has two settings (HFC1, HFC2) for different
distances the cabinets need to cover. The settings should be used
selectively; HFC1 for cabinets covering distances larger than 15 m
(49 ft) and HFC2 for those covering distances larger than 25 m
(82 ft).
The compensation is adjusted for a typical relative humidity of
40 %. With lower humidity the absorption by air increases
therefore the distances where the respective HFC setting provides a
correct equalization are shorter than indicated above.
Using the HFC function provides the correct sound balance
between close and remote audience areas, whilst all amplifiers
driving the array can be fed with the same signal.
