Philips Bosch Praesideo - Product Overview

Easy System Design

Unlike traditional PA systems, the Praesideo uses a network configuration rather than having all system elements connected to a central controller. This architecture gives real freedom in system design. The "daisy-chain" network topology means system elements can be connected (and added at a later date) to virtually any point.

The optical system cabling carries no signals, so no extra wiring is ever necessary. Smaller systems can easily be expanded to match changing requirements, for instance creating new zones. And the flexible system architecture allows any type of equipment to be located wherever is most suitable in the building (for example, power amplifiers closer to loudspeakers).

Reliability

What's more, by connecting the network ends together, a "redundant" loop is created so any break in the cable doesn't affect operation - an important consideration in an emergency system. Automatic switching to spare elements in the system is possible if equipment operation is disrupted.
