Complete Beginner’s Guide to Building a Sound System: Mixer, Amplifier, Speakers & Microphones Explained

Introduction

Building a sound system for the first time can feel overwhelming. With so many options—mixers, amplifiers, speakers, microphones, and portable PA systems—it’s easy to buy the wrong equipment or overspend on features you don’t actually need.

This guide is designed for beginners, event organisers, churches, musicians, and home users who want a clear explanation of how a sound system works and how to choose the right components. By the end of this article, you’ll understand:

  • What each part of a sound system does

  • The difference between powered and non-powered speakers

  • How to match mixers, amplifiers, and speakers correctly

  • Common mistakes to avoid when buying audio equipment

What Is a Sound System?

A sound system is a collection of audio equipment that captures sound, processes it, amplifies it, and plays it through speakers. Sound systems are used for:

  • Live performances

  • Churches and places of worship

  • Events and presentations

  • Band rehearsals

  • Portable outdoor activities

Every sound system—large or small—follows the same basic signal flow:
Microphone / Instrument → Mixer → Amplifier → Speaker

Main Components of a Sound System

1. Audio Mixers – The Control Centre

An audio mixer allows you to control volume levels, tone, and effects for microphones and instruments. It’s where all sound sources come together before being sent to speakers.

What a Mixer Does

  • Adjusts volume for each input

  • Shapes sound using EQ (bass, mid, treble)

  • Adds effects like reverb or delay

  • Sends clean audio to speakers or recording devices

Popular Mixer Options for Beginners

Compact mixers are ideal for small setups:

  • Yamaha MG-06X

  • Yamaha MG-10XU

Mid-size mixers for bands and events:

  • Yamaha MG-12XU

  • Yamaha MG-16XU

  • Yamaha MG-20XU

USB and effects-focused mixers:

  • Wharfedale SL1224USB

  • Wharfedale 1202FX/USB

  • Soundcraft EFX12

2. Amplifiers – Powering Passive Speakers

Amplifiers increase the audio signal from the mixer so it can drive non-powered (passive) speakers. Choosing the right amplifier is crucial to avoid distortion or speaker damage.

Key Things to Consider

  • Power output (watts)

  • Speaker impedance (ohms)

  • Headroom for clean sound

Amplifier Options

High-power professional amplifiers:

  • Wharfedale CPD1600

  • Wharfedale CPD2600

  • Wharfedale CPD3600

  • Wharfedale CPD4800

Lightweight digital amplifiers:

  • Yamaha PX3

  • Yamaha PX5

Multi-purpose amplification:

  • Laney AH-80

3. Speakers – Powered vs Non-Powered

Speakers are the final stage of your sound system. Choosing the right type affects portability, setup complexity, and sound quality.

 

Powered Speakers (Active Speakers)

Powered speakers have a built-in amplifier, making setup simpler—just connect the mixer and power.

Ideal for:

  • Small to medium events

  • Portable setups

  • Quick installation

Popular powered speaker options:

  • Yamaha DBR15

  • Wharfedale DVP-AX12

  • Wharfedale DVP-AX15

  • Wharfedale DVP-AX215

  • Wharfedale DVP-AX18B

  • Wharfedale DELTA-AXF15

  • Wharfedale DELTA-AX18B

👉  Shop powered speakers

 

Non-Powered Speakers (Passive Speakers)

Passive speakers require an external amplifier, offering flexibility and scalability for larger systems.

Ideal for:

  • Permanent installations

  • Large venues

  • Custom sound setups

Top non-powered speakers:

  • Wharfedale EVP-X12 MKII

  • Wharfedale EVP-X15 MKII

  • Wharfedale EVP-X215 MKII

  • Wharfedale DELTA X12

  • Wharfedale DELTA X15

  • Wharfedale DELTA X215

Subwoofers for deeper bass:

  • Wharfedale DELTA-X18B

  • Wharfedale DELTA-X218B

  • Wharfedale IMPACT-X18B

  • Wharfedale IMPACT-X218B

4. Microphones – Capturing the Sound

Microphones are the starting point of any sound system. The right microphone improves clarity, reduces feedback, and enhances performance.

Vocal Microphones

  • Wharfedale DM57

  • Wharfedale DM-57

  • Wharfedale DM5.0 PRO

  • Wharfedale DM5.0S (single & set)

  • Smart XLR vocal microphones

Wireless Microphones

  • Wharfedale AEROLINE Vocal Wireless

  • Smart SWM260HT Wireless

Instrument Microphones

  • Wharfedale KMD-7

5. Portable PA Systems – All-in-One Convenience

Portable PA systems combine speaker, amplifier, and mixer into a single unit. They are perfect for:

  • Small events

  • Outdoor use

  • Public speaking

Recommended portable PA systems:

  • Sekaku 25W Portable PA

  • Sekaku 40W Portable PA

  • Wharfedale EZ-12A

  • Yamaha 400BT

  • Yamaha 600BT
