The d&b System reality
As the name implies a d&b system is not just a loudspeaker.
Nor is it merely a sum of the components: loudspeakers, control
electronics, mechanical accessories and remote control. Right
from the outset the d&b audiotechnik approach was to build
integrated sound reinforcement systems that were more than the
sum of their parts. Each element is tightly specified, precisely
aligned and carefully integrated to achieve maximum possible
performance, along with neutral sound characteristics. At the same
time d&b offers integrated training, technical information, expert
service and support, as well as a knowledgeable distribution
network, so that the same optimal acoustic result is achieved by
every system anywhere, at any time.
4 d&b Q-Series
The Q-Series
The Q-Series embodies the d&b holistic approach to sound
reinforcement solutions: integrating loudspeakers, electronics,
mechanical deployment assemblies, remote control functions and
setup design tools for precise calculation of array performance.
Control of dispersion behaviour is a particular fixation at d&b,
while at the same time keeping the size and weight of systems to
an absolute minimum. The Q-Series maintains the ”d&b specific”
combination of a neutral, intelligible sound character that is
clear and transparent even at high sound pressure levels
providing the engineer with an efficient, effortless tool and a
neutral platform.
The Q-Series loudspeakers are the perfect option for speech and
music in many theatre and presentation situations, live television
and orchestral shows, situations where multiple open microphones
are used and considerable gain before feedback is an absolute
requirement. The transparency, bandwidth, high power and
headroom capabilities, also make them ideal for any type of
amplified music. The scope of applications is intentionally broad,
ranging from single loudspeakers right through to larger multiple
cabinet arrays. To this end a variety of technologies are used:
conventional rotatable CD horns, dipolar driver arrangements,
low compression vented designs with high excursion drivers and
toroidal wave shaping devices, all integrated using line array
principals.
The Q and Qi loudspeakers are designed for mobile and
installed applications respectively, the Qi versions differing
only in cabinet construction and mounting hardware. The Q
loudspeakers are designed for a wide range of small to medium
scale applications with a clear perspective to provide mobile,
flexible, configurable array solutions to the most arduous sound
reinforcement situations. The d&b ArrayCalc calculator predicts
the performance of arrays, enabling simple and accurate system
planning. The Qi loudspeakers are intended for permanently
installed performance spaces where the specification is rider
driven by the artist or mix engineer’s preferences. Both the
Qi cabinets and mounting hardware can be properly colour
matched to interior designs, are mechanically adapted for
installation use and can provide protection in climatically hostile
environments.
The 2-way passively crossed over Q1/Qi1, Q7/Qi7 and
Q10/Qi10 loudspeaker cabinets sharing the same physical size,
shape, rigging and driver compliment. The highest degree of
constant directivity is maintained using a large frequency overlap
through the crossover range, while the recessed dipolar positioning
of the two 10” low frequency drivers mechanically time aligns
these with the 1.3” exit HF driver. The Q1/Qi1 HF drivers are
fitted with a toroidal wave shaping device, which have a 75° (h)
and 75° x 15° (h x v) dispersion pattern respectively, the resulting
curved coherent wave front allows vertical arrays of multiple
cabinets to be constructed. The Q7/Qi7 and Q10/Qi10
loudspeakers also use a 1.3” HF driver fitted to rotatable 75° x 40°
and 110° x 40° (h x v) constant directivity horns respectively
allowing them to be configured for use both vertically or
horizontally. When deployed upright, the Q7/Qi7 and Q10/Qi10
are accurate stand-alone full range loudspeakers with vertical
directivity control extending approximately one octave below
similarly sized biaxial loudspeakers. Their horizontal coverage
angles can also be used to fulfil near field or infill functions
for Q1/Qi1 arrays, either flown, stacked or ground supported.
When deployed horizontally with the horn rotated, the horizontal
dispersion control of the Q7/Qi7 is maintained down to
approximately 400 Hz. This performance can be used very
effectively in critical positions close to open microphones and
also allows the Q7/Qi7 loudspeakers to be combined as the
near field element in Q1/Qi1 columns.
The Q, Qi and QiCSA subwoofers complete the Series’ sharing
the same width as the other loudspeakers and having compatible
flying fittings that enable their use in columns with Q and Qi
loudspeakers respectively. The Q, Qi and QiCSA-SUB cabinets are
bass-reflex designs with an 18” high excursion driver. Multiples
of three Q-SUBs or two Qi-SUBs and one QiCSA-SUB can be
combined to produce Cardioid Subwoofer Arrays (CSA) when
driven by the D6 or D12 amplifier. The D12 amplifier incorporates
d&b SenseDrive technology for accurate control of LF driver
membranes.
The d&b D6 and D12 dual channel amplifiers realize the
complete system. They provide two different power ranges,
incorporate d&b loudspeaker specific configuration information
and have analog and digital signal inputs and links. These devices
are specially designed and manufactured by d&b utilizing Digital
Signal Processing and include switchable functions for precisely
tailoring system response for a wide variety of applications. A user
definable 4-band parametric equalizer and a delay capability is
provided in every amplifier channel to reduce the need for external
processing devices. The D12 amplifier additionally offers a
2-Way Active mode and a MIX TOP/SUB output configuration,
output connector options as well as d&b SenseDrive.
The D6 and D12 amplifiers have d&b Remote network
interfaces enabling control and monitoring of a large number of
system functions and extensive system integration capabilities.
d&b Load monitoring and System check are also incorporated to
remotely monitor loudspeaker driver status.

Q1 and Qi1 loudspeakers
The Q1 and Qi1 are line array loudspeakers for use in vertical
columns. The Qi1 is the installation version of the Q1 loudspeaker,
it differs only in cabinet construction and mounting hardware.
The Q1 and Qi1 cabinets are passive 2-way designs that houses
2 x 10” LF drivers and a 1.3” HF compression driver with a toroidal
waveshaping device to achieve a 75° horizontal dispersion
characteristic. The two 10” neodymium LF drivers are positioned
in a dipolar arrangement providing an exceptional dispersion
control even at lower frequencies, with the 75° nominal dispersion
angle being maintained down to 400 Hz.
Q1 and Qi1 cabinets can be combined with the respective Q and
Qi subwoofer systems: in mixed line array setups, as a separate
subwoofer column or in ground stacked applications. For further
extension of bandwidth and headroom ground stacked J-INFRA
subwoofers can be used.
The Q1 and Qi1 cabinets are constructed from marine plywood
and have an impact resistant paint finish. The front of the
loudspeaker cabinets are covered with a replaceable acoustically
transparent foam and protected by a rigid metal grill. Four M10
threaded inserts on each side panel of the Qi1 cabinet enclosure
are provided for attaching installation hardware whilst the Q1
cabinet incorporates a pair of handles and has integrated line
array rigging hardware.

The Q1 rigging examples
With a 15° vertical HF dispersion per cabinet, the Q1 can be
used to construct vertical columns that produce a curved coherent
wave front. The mechanical and acoustical design of the cabinet
enables vertical splay angles to be set between 0° and 14°. Q1
cabinets can therefore be used in vertical configurations starting
from two cabinets with a 15° to 30° dispersion, up to twenty
cabinets with a fully user and venue defined vertical profile.
