System Overview
1. About Network PA System
Network public address is a computer network technology based modular structured and highly integrated and
intelligent public address system.
The system realizes digital transmission and takes LAN as its transmission medium, and the transmission distance
may be over a dozen kilometers. The existing LAN architecture may be used so that projects adopting the device
can be constructed quickly and efficiently. It realizes fusion of multiple network and breaks the limitations that
traditional public address systems can only realize download and can be only controlled at the computer room, by
providing powerful interactive functions.
The network public address device is compatible with terminals with various functions, including player terminals,
VOD terminals, paging terminals and one-button emergency calling terminals etc. The device is composed of a
player, a zoning mechanism, a timer and an equalizer; in addition, it also provides powerful audio matrix function.
The network public address system is applicable to airports, wharves, college towns, schools, large gatherings
(such as the Expo Park), gymnasium, industrial parks, parks, rail transit and expressways, etc.
2. Features
A public address system with complete functions.
The system realizes digital transmission and takes LAN as its transmission medium, and the transmission
distance may be over a dozen kilometers.
The existing LAN architecture may be used so that projects adopting the device can be constructed quickly
and efficiently and fusion of multiple networks is realized.
It breaks the limitations that traditional PA systems can only realize download and be controlled by machine
room, with powerful interactive functions.
It supports infinite number of zones and such zones and groups can be organized and reorganized without
rewiring.
Audio can be scheduled and programmed and the system operates in accordance with preset programs in an
unattended manner. Various types of audio can be set as regular rings to be played manually or at a preset
time of each day. Zones also support separate schedule operations and playing different programs at a same
time and at various volume levels.
Programs on terminals: The controller may designate audios to be played on each terminal or the terminals
may play any audio available on the controller.
Override paging: The master controller may page any single or all zones and can accept phone paging.
Intercom Function: If the system set many zones, then there may be several groups of one-to-many terminal
paging between the zones. Two terminals can be intercom with each other.
Remote control: Any computer in LAN, on which the control software of the system has been installed, and it
may take control over or modify the operation of this system.
