datasheets and installation manual. See Related documentation, page 7
Introduction to PRAESENSA
With PRAESENSA, Bosch has set a new standard in Public Address and Voice Alarm systems.
With all system elements being IP‑connected and using state‑of‑the‑art technologies, this
system combines cost efficiency and audio quality with ease of installation, integration and
use. IP‑connectivity and amplifier power partitioning enable new levels of scalability and
adaptability, and combined with local backup power facilities this makes PRAESENSA equally
suited to both centralized and decentralized topologies. PRAESENSA uses only a few different
but very flexible system devices, each with unique capabilities, to create sound systems of all
sizes for an extremely wide range of applications. PRAESENSA fits to an office with
background music in the reception area and some occasional calls, as well as to an
international airport with many simultaneous (automated) announcements for flight
information, and carefully selected music programs in lounges, restaurants and bars. In all
cases, it can be installed to operate also as a certified voice alarm system for mass notification
and evacuation. System functions are defined and configured in software and system
capabilities can be enhanced via software upgrades. PRAESENSA: one system, endless
options.
Introduction to OMNEO
PRAESENSA uses OMNEO network technology. OMNEO is an architectural approach to
connecting devices that need to exchange information such as audio content or device
control. Built upon multiple technologies, including IP and open public standards, OMNEO
supports the technologies of today such as Audinate's Dante while adopting the standards of
tomorrow, such as AES67 and AES70. OMNEO offers a professional-grade media networking
solution that provides interoperability, unique features for easier installation, better
performance and greater scalability than any other IP offering on the market.
Using standard Ethernet networking, media products that integrate OMNEO can be assembled
into small, medium and large networks that exchange studio-quality synchronized
multichannel audio and share common control systems. OMNEO's media transport technology
is based on Audinate's Dante, a high performance standards-based, routable IP‑media
transport system. OMNEO's system control technology is AES70, also known as Open Control
Architecture (OCA), an open public standard for control and monitoring of professional media
network environments. OMNEO devices are fully compatible with AES67 and AES70, without
losing any functionality.

Security precautions
PRAESENSA is an IP‑connected, networked Public Address and Voice Alarm system. In order
to ensure that the intended functions of the system are not compromised, special attention
and measures are required during installation and operation to avoid tampering of the system.
Many of such measures are provided in the PRAESENSA configuration manual and installation
manual, related to the products and the activities described. This section provides an
overview of precautions to be taken, related to network security and access to the system.
