Professional School Sound System Consulting

In the modern educational environment, the public address system plays an indispensable role in transmitting information, managing class hours, playing background music and making emergency announcements. A properly designed sound system not only helps the sound to be clear and cover the entire campus, but also demonstrates professionalism, safety and efficiency in operation.

To select standard school announcement sound equipment, it is necessary to follow 4 main technical principles: choose speakers suitable for each area, choose a central amplifier with a capacity 20-30% larger than the total speaker capacity and support dividing the broadcasting area, choose a microphone suitable for the purpose of use, and add auxiliary equipment to ensure the system operates stably, neatly and safely.

With years of experience, Phuc Truong Audio specializes in providing complete school sound solutions from classrooms, schoolyards, hallways to auditoriums and multi-purpose stages. Professional processes, genuine products and dedicated service policies promise to bring the most satisfaction to schools.

Why Install School Public Address System?

Public address systems help schools operate more efficiently, safely and professionally. Here are five important reasons why installation has become a must for every educational institution today.

Convey information quickly and accurately

The public address system helps school administrators and staff communicate information instantly to all students and teachers in all areas: classrooms, hallways, schoolyards, administrative areas, canteens or dormitories.

When urgent announcements are needed (such as schedule changes, power outages, lost items, or urgent news), audio ensures information is conveyed immediately, saving time and minimizing risk compared to manual announcements.

Effective support for teaching and administration

A good sound system helps teachers teach more conveniently, especially in crowded classrooms.

Clear, stable sound helps students absorb better, while reducing pressure on the teacher's voice. In addition, schools can use this system to play soft background music during breaks, creating a more friendly and positive learning atmosphere.

Not only serving the classroom, sound also supports council meetings, flag-raising activities, opening and closing ceremonies, helping to convey content coherently and clearly even in large spaces.

Ensuring safety and effective emergency management

In emergency situations such as fire, power outage, natural disaster or evacuation, the school-wide loudspeaker system becomes the fastest and most accurate means of warning.

Thanks to the loudspeaker broadcasting throughout the area, administrators can guide students to move safely, maintain order and control the situation. This is a mandatory factor for schools that meet fire safety standards or ISO standards in education.

Support the organization of extracurricular activities and events

Not only serving teaching, the public address system also helps organize events more easily: from ceremonies, sports festivals, extracurricular activities to art and sports programs.

The evenly distributed sound helps students and teachers follow the program clearly, increasing the connection and excitement in group activities. When combined with wireless microphones, mixers and high-power speakers, this system can also be flexibly used as a small stage sound system for internal school use.

Increase professionalism and modernity for the school environment

A school equipped with a synchronized, aesthetic and stable public address system not only improves management efficiency but also presents a professional, modern and safe image.

This is a factor that helps parents and students appreciate the quality of facilities, and at the same time creates a distinct mark in enrollment, especially for international schools, private schools and skill training centers.

Principles for Choosing Standard School Announcement Sound Equipment

A standard school announcement sound system not only ensures that the volume covers the entire campus, but also helps the voice to be clear, not howling, not distorted and stable for a long time. To achieve that, choosing the right equipment plays a decisive role. According to Phuc Truong Audio's experience, below are 4 important technical principles that you need to know when choosing each item for the system.

Choosing Speakers – The Decisive Factor of Sound Quality

Speakers are the most important component in a public address system. When choosing speakers, consider the area, ambient noise level, and installation location:

• Outdoor area / school yard: You should choose a horn speaker (loudspeaker) with a capacity of 15W - 60W, wide sound coverage angle, IP65 waterproof material to ensure stable operation in rain and sun.
• Hallway, classroom: Suitable for wall-mounted speakers or ceiling speakers with capacity from 6W - 30W, soft sound, not harsh.
• Meeting room, office: You should use full range speakers or floor standing speakers to reproduce voices more clearly and elegantly.

Note: Choose speakers with high impedance (70V/100V) to flexibly connect many speakers at the same time, avoiding signal loss when pulling the wire far away.

Choose Amplifier - Sound Amplifier Center for the Whole System

The amplifier is the “heart” of the public address system, responsible for amplifying the signal and distributing power to the speakers.

• Amplifier capacity must be 20-30% larger than total speaker capacity to help operate stably, avoid distortion or overload.
• You should choose an amplifier with multiple outputs (zone output) to divide the broadcasting zone into separate areas such as classrooms, schoolyards, offices, and dormitories.
• Amplifier should integrate zone selection function, Bluetooth, USB, FM, AUX, Micro Priority (microphone priority) for easy operation in emergency situations.
• For large systems, you should use a high-power amplifier or a power amplifier combined with a pre-amplifier mixer for powerful, stable sound and easy expansion later.

Choose Microphone – Main Voice Recording Device

Microphones used in schools are usually of two types: fixed microphones and wireless microphones, depending on the purpose of use.

• Executive room / office: Use a desktop gooseneck microphone for clear sound, noise cancellation, suitable for making announcements.
• Stage, events, flag salute: Choose a UHF wireless microphone with long transmission distance, good anti-interference, and durable battery.
• Teachers/MCs move around a lot: Should use lapel microphone or headset microphone for hands-free operation.

Prioritize microphones with wind filter, anti-howling, high sensitivity (-50dB to -60dB) for natural, undistorted voice.

Select Other Equipment (Auxiliary Kit – Conductor – Anti-Howling Kit)

Besides the main equipment, the school announcement sound system also needs some important accessories to ensure stable and safe operation:

• Zone selector: used when it is necessary to broadcast announcements to separate areas.
• Feedback Suppressor: Helps eliminate hissing and keep sound clear when using multiple microphones.
• Audio rack: Protect central equipment, keep the system neat and aesthetic.
• Speaker wire and signal wire: You should choose pure copper wire with cross-section ≥1.5mm² to reduce loss, especially when pulling wires hundreds of meters long.
• Uninterruptible Power Supply (UPS): Helps keep the system running for a few minutes during a power outage – crucial in an emergency.

Suggested Configuration for Installing School Sound Systems by Area

Each area – from classrooms, hallways, schoolyards to multi-purpose halls – has different acoustic characteristics and purposes. Below are suggestions for three standard school sound configurations, Phuc Truong Audio Design based on implementation in many educational institutions nationwide.

Configuration for standard classroom

The classroom needs clear, pleasant sound, without howling, so that teachers can teach and students can hear clearly no matter where they sit. Phuc Truong Audio Suggested configuration is as follows:

• Wall-mounted or ceiling speakers 30-60W capacity, covers the whole room, realistic sound, easy to listen.
• Amplifier with integrated wireless microphone, support music playback, teaching, general announcements.
• Handheld or lapel wireless microphone for teachers, long battery life and stable signal within 20-30m range.
• Digital signal processing echo (if the room is larger than 60m²) to reduce feedback, filter noise and fine-tune the voice.

This configuration is suitable for general classrooms, foreign language centers or skill classes, ensuring clear, natural sound and energy saving.

Configure the schoolyard and hallway announcement sound system

The schoolyard and hallway announcement sound system is the center of information communication in the school - from rules, schedules to background music at the beginning of class. Due to the large space, the sound needs to be far-reaching, clear, and not distorted when operating outdoors. Suggested configuration:

• Horn speaker or loudspeaker 30–60W capacity for school yard area.
• Wall-mounted speakers or moisture-proof box speakers for hallways, dining areas, dormitories.
• High power central amplifier (≥500W), can divide zones to broadcast separately to each area.
• Desktop microphone or wireless microphone, easy to make quick announcements during class or recess.
• Background music player & automatic timer, allowing for music to be played at the beginning, middle, or for automatic announcements.

This system ensures sound coverage throughout the campus, suitable for elementary schools, middle schools, high schools, colleges - universities, or training centers with large campuses.

Multi-purpose hall and stage sound configuration

Multi-purpose halls or stages are places for meetings, performances, rallies, graduation ceremonies, seminars, teacher training, etc., so they require a powerful, clear and flexible sound system. Standard configuration includes:

• Pair of full power speakers 300–500W (depending on area 100-300m²), for vivid, clear sound.
• Subwoofer capacity 500–800W, helps enhance the bass range, giving depth and power to background music or performances.
• Power amplifier + digital mixer / digital mixer, helps control volume, prevent feedback, and balance voices and instruments.
• Wireless microphones (2–4 sets) for speaking, performing, hosting.
• Power processor and technical rack, helps manage all equipment safely, neatly and professionally.

This is the configuration Phuc Truong Audio Installed in many school halls, training centers, cultural houses and student living areas, ensuring clear, strong and undistorted sound even when operated for long periods of time.
