What is a Live Sound Amplifier? 

A live sound amplifier increases the strength of an audio signal so it can power passive speakers. It’s a must-have for PA systems used in concerts, events, houses of worship, and public venues. Unlike powered speakers, passive speakers need an external amplifier to function. 

Live sound amplifiers are built for reliability and performance. They’re designed to handle high volumes, long hours of operation, and the demands of live environments. 

At Videopro, we carry models that suit everything from small venues to large-scale productions. You’ll find options with different power ratings, input types, and cooling systems to match your setup. 

Types of Live Sound Amplifiers 

Choosing the right type of amplifier depends on your setup and performance needs. Here are the most common types available at Videopro: 

Class D Amplifiers 

Class D amplifiers are known for their efficiency. They generate less heat and are lighter than traditional models. This makes them ideal for portable setups and long events. 

Benefits: 

• Lightweight and compact 
• Energy-efficient 
• Great for mobile DJs and touring bands 

Class AB Amplifiers 

Class AB amplifiers offer a balance between sound quality and efficiency. They’re often used in fixed installations where weight isn’t a concern. 

Benefits: 

• Smooth sound output 
• Reliable for permanent setups 
• Handles dynamic audio well 

Both types are available at Videopro, so you can choose based on your power needs and mobility. 

Key Features to Look For in Live Sound Amplifiers 

When shopping for a live sound amplifier, focus on features that match your performance needs. Here’s what to consider: 

Power Output 

Check the wattage per channel and match it to your speakers. Too little power can cause distortion. Too much can damage your gear. 

Impedance Matching 

Most amplifiers support 4-ohm or 8-ohm speakers. Make sure your amplifier and speakers are compatible to avoid performance issues. 

Input and Output Options 

Look for XLR, TRS, and RCA inputs. Balanced inputs reduce noise, which is important in live environments. 

DSP (Digital Signal Processing) 

Some amplifiers include built-in DSP for EQ, crossover, and limiter settings. This gives you more control over your sound without needing extra gear. 

Rack-Mount Design 

If you’re building a professional rack system, choose an amplifier with standard rack-mount dimensions. This keeps your setup clean and organised. 

Cooling System 

Live sound amplifiers generate heat. Models with fans or heat sinks help maintain performance during long sessions. 

Benefits of Using a Dedicated Live Sound Amplifier 

Using a dedicated amplifier gives you more control and flexibility than powered speakers. Here’s why many professionals prefer them: 

Scalability - Easily upgrade or replace components without changing the whole system. 

Customisation - Choose the exact amplifier and speaker combination you want. 

Durability - Built to handle the demands of live performance. 

At Videopro, we help you build a system that fits your venue, budget, and performance goals.

Here are some quick answers to common questions about live sound amplifiers: 

What does a live sound amplifier do? 

It boosts audio signals to power passive speakers in live sound systems. 

Can I use a home amplifier for live sound? 

No. Home amplifiers are not built for the power and durability needed in live environments. 

Do I need an amplifier if I have powered speakers? 

No. Powered speakers have built-in amplifiers and don’t need an external one. 

How do I know how much power I need? 

Check your speaker’s RMS rating and choose an amplifier that delivers 1.5 to 2 times that power. 

What’s the difference between Class D and Class AB amplifiers? 

Class D is more efficient and lightweight. Class AB offers smoother sound but is heavier.
