WEP5501 Cloud Broadcast System

Features

● A fully-featured Cloud Broadcast System.
● Fully digital transmission with expandable network transmission capability, featuring approximately 200ms delay for public network broadcasts and 40ms delay for LAN broadcasts.
● Leverages existing network infrastructure for rapid deployment and cost efficiency, achieving multi-line transmission convergence.
● Breaks through the limitations of traditional public address systems that only support downstream transmission, single-network architecture, and centralized control from equipment rooms, offering robust interactive functionalities.
● Supports unlimited zoning with flexible partition and group combinations that can be reconfigured anytime without additional wiring.
● Enables scheduled programming playback, operating automatically per predefined schedules for unattended operation. Supports manual or timed playback of various audio source types for daily schedule bells. Independent timing per zone allows simultaneous playback of different programs at varying volume levels across partitions.
● Terminal playback options: Host can sequentially download scheduled audio sources to terminals, or terminals can independently request programs from the host.
● Priority interruption paging: Central control room can page individual or all partitions via host. Telephone paging becomes available with telephone module integration.
● Intercom functionality: In multi-zone systems, concurrent one-to-many terminal paging is possible across partitions, with direct terminal-to-terminal paging communication.
● Remote Control: Accessible via any LAN or public network-connected computer without software installation—full system operation and modifications available through web browsers.
● Includes fire control center interface for automatic alarm interruption, supporting both short-circuit alarms (alarm cards) and network signal alarms. Active alarms display fire icons on corresponding partition interfaces for clear status visibility.
● Automatic playback resumption upon terminal reconnection, with instant partition information updates after modifications.
● Features more intuitive, user-friendly operation with drawer-style full keyboard input for real-time partition/group name editing.

Introduction
Specification

Cloud Broadcast System is a highly integrated and intelligent public broadcasting system based on computer network technology, constructed in a modular and layered architecture.

The system employs fully digital transmission, primarily using wide area networks (WAN) as the transmission medium, while also supporting multi-network transmission in combination with local area networks (LAN). It adopts a distributed broadcasting approach, enabling multi-point control within LAN environments without being rigidly constrained by the host device. Under WAN conditions, the host serves as the core service unit. The system integrates multiple transmission methods, breaking the limitations of traditional public broadcasting systems that only support downstream transmission, single-network deployment, and centralized control from a control room. It boasts robust interactive capabilities.

The Cloud Broadcast Host is compatible with various functional terminals, including playback terminals, on-demand terminals, paging terminals, and one-touch emergency assistance terminals. The host itself integrates an audio source player, preamplifier, timer, equalizer, and can be expanded with fire alarm interfaces, zone controllers, 4G network modules, FM radio, and FM modulation functions. It also features powerful audio matrix capabilities.

The Cloud Broadcast System is suitable for diverse applications such as airports, ports, university campuses, schools, large-scale event venues (e.g., expo parks), sports stadiums, industrial parks, parks, rail transit systems, village broadcasting networks, emergency broadcasting, and highways, demonstrating exceptional performance characteristics.
