Simplified Analog Intelligent PA System for Kindergartens

System Overview

PA System for Kindergartens

The public address system for kindergartens is a device used to deliver information to students and faculty in a kindergarten. It is usually comprised of a central controller and multiple speakers to broadcast music, educational content, notifications, etc. The background music and content of the public address system should be consistent with the educational objectives and values of the kindergarten, and should be positive and meaningful. Meanwhile, the broadcasting system should provide good sound quality and volume control to ensure that the message can be clearly conveyed to every listener.

Requirements Analysis

Clear sound: The system should provide good sound quality and deliver clear and natural sound, so as to ensure that students and faculty can obtain the details and content of the message.

Adjustable volume: The system should feature adjustable volume to adapt to different scenarios and requirements. For example, turn up the volume for indoor activities, while turn down the volume for quiet teaching classes.

Zone control: The system should allow zone control, that is, the audio content can be selectively delivered to designated zones or speakers to address the needs of different zones.

Design Objectives

It is necessary to take safety into account and ensure that the equipment meets the relevant safety standards, as well as take appropriate measures to prevent accidents from occurring.

The system is easy to use and convenient for teachers and staff to operate and control, so that broadcast content can be delivered to the audience on time and accurately.

It is provided with versatility. For example, it can play different types of content such as music, stories, notifications, etc. to meet the diversified needs of kindergartens.

Solution Configuration

● The six-zone mixer amplifier provides six different speaker zones for different areas of the kindergarten, integrates a variety of line audio inputs, and has built-in Bluetooth, FM and USB playback functions.

● The front-end equipment, speakers and zones need to be set according to the site. The corridors are equipped with 6W ceiling speakers, with two speakers spaced 8-12m apart, the classrooms and teachers’ offices are arranged with 10W wall-mounted speakers, spaced 5m apart from both sides of the blackboard, the outdoor areas are provided with 30W wall-mounted column speakers, with two speakers spaced 25-35m apart, and the playground is set with 30W horn speakers, which are positioned at the top of the security room at the entrance of the school, facing the playground. The zones can be defined by a certain functional area or by floor.

● The remote paging station used with the six-zone mixer amplifier adopts touch key technology and glass panel technique, with anti-fingerprint coating on the surface for smooth touch, and high-gloss bevelled edge cutting for exquisite and beautiful shape, emphasizing the fashionable sense of aesthetics. It is easy to operate and provided with intuitive signal display and corresponding on/off switches for the 6 zones of the mixer amplifier, allowing for convenient and quick call switching. The paging station is characterized by strong stability and low failure rate.

● The amplifier can be connected to fire alarm short-circuit signals or fire audio signals, with priority over the microphones and background music.

System Advantages

● The system is easy to use and convenient for teachers and staff to operate and control, so that broadcast content can be delivered to the audience on time and accurately.

● The broadcast signal is relatively stable and not susceptible to interference, and can maintain good transmission quality even in bad weather or complex terrain.

● As the equipment is relatively simple with comparatively low technical costs, the simplified analog intelligent public address system is a more affordable and cost-effective option for some resource-constrained regions or developing countries.

Application Scenarios

The simplified analog intelligent public address system is suitable for schools, shopping malls, factories, supermarkets, bookstores and other public places.
