Best Generator for Live Sound Buyer’s Guide:

Now that you’re familiar with the best generators ideal for live sound, it’s time I get to tell you the few things to look at while making your selection. Here are the top factors to consider if you want to buy the right generator for your live sound systems.

Power output

You need to estimate the power the system requires to run concurrently. For you to do that, you need to list all your live sound systems, appliances, and electronics. Once you’ve done that, calculate the total power needed by adding up their wattage rating. If the appliance doesn’t have the watts rating, then you will have to calculate using this formula:

Watts = volts x amps

Remember to consider both starting and running wattage for the motor-driven appliances like the amplifier or fan. Once you have the total wattage, use that to size the generator. Pick a generator that gives you 20% extra power.

Run Time

A live sound is an event that doesn’t go well with power interruptions. That’s why you have to make sure you have bought a generator that can give you enough run time. It needs to provide reliable power during the entire performance without needing refilling.


A generator is an investment that you buy to provide you with power, not for a day buy for years to come. And to ensure you get this right, you need to consider a model that features high-quality materials. A generator with a frame, the frame needs to be of high-quality, rust-resistant metal. The engine should also have some protection to keep it rust and damage-free. If it’s an inverter generator, then you need to make sure that the casing is UV-resistant and also hard-break.


Noise is something we all don’t like. It happens that sound systems also need to be loud enough, and that can’t happen if they are fighting for the loudness with your generator. That’s why I advocate you buy a super-quiet model that gives you some peace of mind while you play your live sound system.


Live sound at times might be outdoors, and that will require you to move your generator here and there. That calls for an easy-to-move unit, which is lightweight and also compact. That way, it’ll be hassle-free to move it out of storage and back. Additionally, with a portable generator, it will be much easier to carry it with you when live sound event demands you move to a new place or city.

Best Generators for Live Sound (FAQs)

Do I need a transfer switch to connect my portable inverter generator to my live sound systems?

You don’t unless you will be using it as a backup. When you connect the systems directly to the generator, with no electric line involved, you do not need a transfer switch at all.

Why is an inverter generator the most recommended type for use with live sound?

An inverter generator is lighter, compact, quieter, and more efficient compared to conventional generators. It’s designed to produce more electrical energy per a single-engine rotation. It’s more reliable and lighter.


There you’ve it; everything you need to buy the ideal generator for use with your live sound. Everything I have provided here will help you settle on a robust, reliable, and efficient generator. It’s up to you now to use the guide to make the best decision. Good Luck!
