XA Series


The xA-Series loudspeakers are 2-way, passive high performance
cabinets employing a single 10″ driver in a bass-reflex enclosure
and offer different HF sections that enable the design of
vertical or horizontal point source arrays as well as vertical line
arrays� The biaxial 10A/10A-D are point source cabinets that
have rotatable horns delivering additional flexibility in terms of
the placement options of the loudspeakers� Whilst the biaxial
10AL/10AL-D line source loudspeakers enable the design of
line arrays offering vertical and horizontal coverage tailored to
specific reinforcement tasks�
The xA-Series loudspeakers are supported by the compact
bass-reflex subwoofers 18A-SUB and 27A-SUB of which the
27A-SUB has an integrated cardioid setup� The 18A and 27A
subwoofers rigging hardware allow them to be integrated into
vertical 10A/10A-D and 10AL/10AL-D arrays or used as
stand-alone columns� The 18A-SUB completes all program
material with that deep, round, warm and musical low end of
today’s performance expectations� The 27A-SUB’s patented
cardioid dispersion avoids unwanted energy behind the system
and greatly reduces the reverberant field at low frequencies
providing highest accuracy in low frequency reproduction�
The special passive cardioid design of the 27A-SUB can be
powered by a single amplifier channel only and offers a highly
economic medium sized subwoofer�
The xA-Series cabinets and accessories are available with
a Weather Resistant (WR) and special colour (SC) option�
The WR option provides an IP34 rating, and enables operation
of loudspeakers in changing ambient conditions, however it is
not intended to enable permanent, unprotected operation of
loudspeakers outdoors� The Weather Resistant cabinet is supplied
with a fixed cable with a PG cable gland, coated with PCP
(Polyurea Cabinet Protection) and is available in black only� The
SC option for all loudspeaker cabinets and most accessories can
be executed in all RAL colours�

The d&b software offering aides the entire system setup process�
The d&b ArrayCalc Simulation software allows the virtual
optimization of loudspeaker line arrays, point source and column
loudspeakers as well as subwoofers and their adjustment to
venue conditions�The configuration simulated in ArrayCalc is
assimilated by the d&b R1 Remote control software into
an intuitive graphical user interface to manage the whole system
from anywhere in the venue�
d&b amplifiers are specifically designed for use with d&b
loudspeakers, and are at the heart of the d&b system approach�
These devices containing extensive Digital Signal Processing
capabilities to provide comprehensive loudspeaker management
and specific switchable filter functions to precisely target the
system response for a wide variety of applications�
The installation specific four channel 30D amplifier is intended
for permanent integration within venues which require medium to
high Sound Pressure Levels� It provides extensive user-definable
equalization containing two 16-band equalizers with
parametric, notch, shelving and asymmetric filters as well as
delay capabilities of up to 10 seconds� The 30D is accessible
via the intuitive web interface through a browser as well as the
R1 Remote control software�
The DS10 Audio network bridge provides 16 AES3
outputs and interfaces between the Dante audio transport
protocol and the d&b amplifiers�
The DS100 Signal Engine is based on a specialized
rack mount 3 RU audio processor with Audinate Dante
networking� It provides a 64 x 64 audio matrix with level
and delay adjustments at all cross points� Additional software
modules provide dynamic source positioning and emulated
acoustics functions�

10A/10A-D loudspeaker
The biaxial 10A/10A-D are high performance 2-way point
source loudspeakers employing a single 10″ driver in a
bass-reflex enclosure and different HF sections for a wide range
of installedsound applications� All models are lightweight passive
designsusing neodymium drivers and large constant directivity
horns for accurate pattern control� The 10A/10A-D are
arrayable cabinets with rotatable dispersion characteristics of
75° x 50° and 110° x 55° respectively�
With their frequency response from 60 Hz to 18 kHz both
versions can be used as full range systems or be supplemented
by different subwoofers from either the xS or xA-Series� The 18A
or 27A subwoofers can also be integrated into the array�
The enclosures are constructed from marine plywood with an
impact resistant black paint finish� The front of the loudspeaker
cabinets are protected by a rigid metal grill backed by an
acoustically transparent foam, whilst the side panels have an
integrated rigging system� The loudspeakers are Ball Impact
Resistant according to DIN 18032-3 for sports and
multipurpose halls�
