ProAnnounce Digital Routing System

Overview

This extraordinarily flexible and versatile system allows the configuration of either small or complex installations. Most functions are realized through software modules, which - when compared to conventional PA-systems – not only reduces the amount of cabling but also the costs. Next to extensive audio signal generating and distribution functions, the ProAnnounce system provides ample control functions. On one hand, these functions offer the possibility to register and rate external events, as well as to control different external components, on the other hand. Boolean operations and relations to the internal state of the system can be programmed as well.

The digital ProAnnounce manager DPM 4000 represents the central unit of the system. It is used to control and monitor all connected components via several serial interfaces.

The kind and amount of connected audio sound sources, amplifiers, and relay board assemblies are extremely variable. This allows configuring the system to basically match any requirement. The system is capable of managing up to 16 paging stations and up to 100 output lines. More than 150 control inputs and outputs are available for controlling and monitoring purposes providing the possibility to generate and manage logic levels and analog levels as well.

Configuration and documentation of a ProAnnounce system installation is established through the use of the ProAnnounce Designer software – a comfortable graphical user interface that runs on a PC under Windows. This allows changing the system’s setup at any time to meet new requirements, without the need to alter the actual installation. The PC has to be connected to the system only when loading or changing its configuration. During normal operation, PC-interaction is not necessary. Anyway, in most cases the permanent connection of a computer bears benefits, like displaying detailed status reports or the printing of protocols. It also offers the possibility for remote diagnosis and remote maintenance via modem.
