Bosch Praesideo system overview
Praesideo is a fully digital public address system that meets
all the requirements placed by professional users on a public
address/emergency system. The system brings highly innovative
and advanced digital technology to the public address market.
The processing and communication of both audio signals and
control data entirely in the digital domain makes the system
superior to other currently available public address and emergency
sound systems. Digital signal processing allows significant
improvements in audio quality to be achieved. The Praesideo
system is designed for configuration from a PC, which makes
installation and setting of operating parameters very simple
and user-friendly.

Digital
processing
All audio processing is performed in the digital domain. Communication
between the units is via plastic fiber or glass fiber cabling,
depending on the distance between the units. The cabling uses
the daisy chain principle. This makes the cabling and installation
very quick, simple and easy. The system cabling is a closed
loop, which allows redundancy to be achieved.
User-friendly Software
Control
The system is supplied with user-friendly software for system
configuration. This allows all system functions to be configured.
The software is based on web technology, which gives authorized
users full freedom of configuration in terms of time and location.
The software also provides clear indication of any parameters,
which have not been programmed before exiting from any stage
of the configuration process.
Network Approach
The system architecture is based on daisy-chaining of the units.
It is possible to add or remove equipment anywhere in the network
without affecting the performance of other units, provided that
the network connection is available. This makes the system easily
expandable, users can start with a small system in the initial
stage and expand the system later simply by adding new units
to the network. The system can be configured for redundant cabling
using a ring cabling structure.
High System Flexibility
The Praesideo system is a highly versatile system which gives
the user a high degree of flexibility in the number of zones,
call stations, audio inputs and outputs, control inputs and
outputs, etc.
Combination of
Functions
The Praesideo range of equipment has multiple functions combined
in a single unit. This feature drastically reduces the number
of different types of equipment used in the system. For example
functions like audio processing, audio delay, amplifier monitoring
including spare switching and speaker line
monitoring are provided in the power amplifier unit itself.
This makes the overall system highly cost-effective. The flexible
architecture of the Praesideo range of equipment allows the
customer to locate any type of equipment anywhere in the building.
The configuration software enables the user to configure all
the functional parameters. No programming is required at the
equipment end, which drastically reduces the installation and
commissioning time.
Distributed Control
The system is designed for distributed control of various system
functions. The external interfaces, which are control inputs
and outputs can be located anywhere in the network. The processing
of audio input and output signals is located in each unit. This
allows the network controller to concentrate on other activities
like routing of announcement taking actions on control inputs,
etc. As a result the response times are much shorter than for
systems with centralized processing of all signals.
IEC 60849 Certified
The Praesideo range of equipment complies with the various emergency
standards, which are applicable all over the world. In fact
Praesideo is the first system which is certified according to
the IEC 60849 standard. The network controller is capable of
monitoring all the units in the system, from the microphone
capsule of the call station to the loudspeaker line. A built-in
memory stores the last 200 fault messages. Any fault is reported
back to the network controller. The system also meets emergency
requirements for emergency call stations. The open system concept,
with the possibility for large numbers of control.
External Interfaces
The interfaces to the system can be audio, control input or
Ethernet. The ethernet open interface is provided at the network
controller. The audio and control inputs can be anywhere in
the system, for example at the power amplifier, audio expander
or network controller. The system accepts even low-level signals
via the control inputs. The configuration allows the user to
configure the input to initiate the desired actions in the system.
The flexibility to route any input from one system unit to another
makes it possible to use the Praesideo range of products for
a wide range of public address and emergency sound system applications.
Reduced Installation
Costs
The Praesideo architecture uses the daisy chain principle for
both data and audio signals. This makes the system wiring very
cost-effective, using 2 fiber cores for data and audio communication
and a copper wire pair to supply power to the units. Power supply
for the system units can be provided locally if the distances
are very long. Combining various functions in a single unit
also makes the equipment more cost-effective than systems in
which separate units have to be purchased for all the specific
functions. This combination of functions also saves lot of rack
space and further reduces installation costs. |
