A power amplifier is a digital device that converts a low-power signal to a higher one.
They are crucial in signal augmentation applications such as audio systems, radio frequency (RF), and other domains.
In this all-encompassing exhibition, we will discuss the best power amplifiers, how to choose your power amplifier, and examine the top 8 power amplifiers.
How do I choose a power amplifier
It’s one of the most common questions when it comes to the best power amplifier for live sound. It’s critically important that you get the right one since you want a clean, rich sound. However, choosing the wrong amplifier might result in subpar sound or, worse, harm to your speaker or amplifier.
Nominal Impedance and Continuous Power
The first step in selecting the best power amplifier in the world is to read the specifications of your speaker. This way ensures compatibility between your speaker and power amplifier, and you can find these specs at the end of the product listing.
Before jumping into the two main factors of this step, lets define some common terminology here:
- Impedance: The electrical resistance that opposes the flow of electricity between the speaker and amplifier.
- Power: Power is the rate of the transferred energy, measured in watts, and there are two types of energy: dynamic and continuous.
It’s decisive to match the two impedances of the devices you want to synchronize, which are speaker and amplifier in this case. Mismatching the impedances can lead to overheating, or final breakdown of the amplifier.
It’s also important to match the continuous power rates of the two devices. This guarantees that the speaker gets the power it needs to deliver a clean, clear sound.
Number of Channels
Next, you have to define the number of channels required for your setup. There is a relationship between the number of channels and the number of distinct audio signals you want to distribute, as the first depends on the second.
For instance, You can connect several speakers in parallel to a single amplifier channel if they must all play the same audio signal at the same time. Nonetheless, every speaker should have its own amplifier channel if it needs to play audio from several sources or have a separate volume control.

Selecting the appropriate amplifier for your passive PA speaker is essential to getting the best possible sound quality and avoiding any damage.
An amplifier that can deliver sufficient power to match the nominal impedance rating of your speakers is what you should choose.
It is advised that you select an amplifier that provides roughly twice the speaker’s RMS, or continuous power rating, as was previously discussed.
This additional power, referred to as headroom, aids in preventing clipping and distortion, particularly while the audio signal is peaking.
To ensure a reasonable margin of power to manage abrupt surges, it is generally recommended to give 1.5–2 times the continuous power rating of your speaker.

FAQ
Which class of power amplifier is best?
- Class A comes with minimum efficiency, but has the highest sound fidelity.
- Class B is a little bit more efficient, but full of distortion.
- Class AB is good at sound and power.
- Class D gives you the highest efficiency with the smallest footprint.
How many watts is a good amplifier?
As we discussed earlier, you have to determine the impedance and continuous power of your amplifier and match these numbers with the speaker you use. Generally it depends on your specific needs.
