German Engineering Excellence
FOR MORE THAN 60 YEARS, DYNACORD HAS BEEN ONE OF
THE MOST INNOVATIVE AND SUCCESSFUL MANUFACTURERS
OF PROFESSIONAL AUDIO EQUIPMENT.

HISTORY
5
In 1945 Werner Pinternagel,
who was an engineer, founded a
workshop for the repair of radio
devices in the Lower Bavarian
town of Pilsting. The development
and manufacture of audio amplifiers,
which he began at the same time,
became a particular passion.
These pioneering experiences
formed the foundation for over 60
years of expertise in professional
power amplifier technology—
expertise upon which the brand
DYNACORD is able to draw today.
Early results included the KI cinema
amplifier with its output of 25 watts.
The devices of the company, which
in the meantime had moved to
Landau and by then boasted a
staff of four employees, still bore
the brand name ‘Dynaphon’.
From 1948 onwards, mixing and
portable amplifiers bearing the
name DYNACORD were being
sold to an ever expanding circle
of customers. Within a few years,
the rapidly growing company had
become one of the leading enter-
prises in the still young audio
technology industry. Already in
1954, the manual workshop have
given way to industrial production
as the product portfolio continued to
expand. The high-caliber, pioneering
and often visionary products have
been presented ever since at all
important international trade fairs
and marketed successfully throughout
the world. To make it possible to
satisfy the enormous demand,
DYNACORD moved to Straubing in
1958. The workforce, which at that
time numbered 80 employees, con-
tinued to expand rapidly. Several
times, the production facility was
renovated or expanded.
Finally, in 1986 a new plant was
opened in which more than 500
employees now develop, produce
and dispatch the company’s pro-
ducts to all corners of the globe.

BOSCH PRODUCTION SYSTEM

With the introduction of the Bosch Production System
(BPS) at the Straubing works, the brand DYNACORD is
further enhancing its already legendary reputation for
the highest production quality and reliability.
Quality with system is assured by the BPS worldwide in
all Bosch production centres, since absolutely identical
indicators, equipment and processes are applied
systematically throughout the enterprise. Decisions
about which products to produce in which plant are
primarily based on core areas of competence.
The same goes for the development. The first measures to
guarantee quality are applied as early as the deve-
lopment phase of a product, where the ‘thermal and
mechanical stability’, the ‘secure functioning of the
circuitry’ and the demands of quality such as the
acoustic performance and the product functions
themselves are all ascertained in advance and rigorous
tests conducted before any final decisions are taken
about the design.
Decades of experience and the most modern quality
management systems guarantee the extraordinary quality
and legendary reliability of DYNACORD products.

largest audio measurement halls. One of the particular
strengths of the brand DYNACORD is the fact that
over the many years of its history profound know-how,
covering the entire signal chain from the mixer to the
loudspeakers has been acquired.
This advantage, coupled with its traditionally close
relationship with users, has yielded many unique so-
lutions to once-vexing problems and helped DYNACORD to
develop a reputation the world over as a manufacturer
of top-flight audio equipment on the absolute cutting
edge of development.
Additional capacity is available at the Bosch
plant in Zhuhai, China, where the production also
conforms to the BPS and quality controls are
conducted using identical procedures and equipment. Manufacturing in Zhuhai, China

The full-range speakers of the D-Lite
series are extremely light, mechanically
durable polypropylene cabinets for
professional portable and fixed
installation sound reinforcement
applications in small to medium-sized
venues.
The wide range of mounting accessories
available for the enclosures and their
tasteful styling permit them to be used
without problems in critical fixed in-
stallation applications. Being of poly-
propylene, the enclosures are capable
of withstanding the roughest handling
during transport and use. The integration
of the constant directivity HF horns into
the baffle is CAD-optimized. The robust
powder-coated steel grilles at the front
of the enclosures are backed by black
acoustic foam plastic. Both the Speakon
sockets in the connection panels are
recessed to allow the cabinets to be operated
in cramped locations.
The beveled sides of the enclosures allow
them to be used without problems in
monitor applications in which more bass
extension is required than that provided
by typical monitor loudspeakers. Robust
handles, integrated stand adapters, and
a wide range of flying and mounting
accessories facilitate the transport and
setting up of the enclosures as well as
allowing them to be ideally positioned
and aimed. Very powerful amplifiers can
be used to achieve the widest possible
dynamic range, as the loudspeakers of
the D-Lite series offer very high pow-
er handling and are for the most part
afforded additional reliable protection by
the fully electronic Voice Coil Tracking
Protection system, as well as halogen
protectors against thermal overload. The
internal passive crossovers are optimized
for long throws and even dispersion, allowing
D-Lite cabinets to be used under acoustically
unfavorable conditions.

Suitable active and passive subwoofers
implemented as vented direct-radiating
enclosures permit flexible system
configurations.
The reflex systems of these subs, when
compared with conventional bass reflex
ports, are characterized by less flow loss
and less wind noise. High sound pressure
levels at very low frequencies are generated
with considerably less distortion than is
the case with conventional bass-reflex
ports.
POWERSUB 315
The passive varieties can, as a result of
their integrated low-pass filters, simply
be operated parallel to the various passive
full-range boxes.
The active single-channel subs possess
crossover outputs for the creation of
active three-way systems with e.g. the
models D 8A or D 11A. The three-channel
subs already possess the requisite power
amplifiers for passive tops and permit in
the simplest manner the configuration of
so-called ‘satellite systems’.

It is remarkable in its class for
the very high sound pressure
levels it is capable of achieving as
well as its outstanding audio
performance.
The wide range of mounting accesso-
ries available for the enclosure and
its tastefully understated styling
permit its convenient use even in
critical applications in the fixed
installation sector.
The housing is made from ABS
and capable of withstanding the
roughest handling during trans-
portation and use. The D8‘s bass
and midrange is the responsibility
of the DND8200-8 low-distortion
neodymium woofer. The integration
into the baffle of the symmetrically
radiating Constant Directivity high
frequency horn, with its nominal
radiation angle of 90° x 90° (hori-
zontal x vertical) and Electro-Voice
DH3 driver, is CAD-optimized.
With power handling of 250 W (rated)
and 1,000 W (peak), a maximum
SPL of 124 dB and a frequency range
of 65Hz - 20 kHz, the D8 performs
outstanding service not only as a
full-range cabinet but also as the
mid / high component of active and
passive satellite systems of superior
quality. The crossover is optimized
to achieve a long throw and a very
even sound pattern, permitting the
use of the D8 even in unfavorable
acoustic environments.
The loudspeaker components are
guarded by thermo-switches and
halogen protectors against thermal
overload.
The front is clad in black acoustic
foam with a robust, powder-coated
steel grille. The SPEAKON sockets
on the connection panel are re-
cessed. The enclosure is trapezoidal
in shape, making it suitable also
for monitoring applications.
