It’s about drive and power — power amplifiers, to be precise. These are essential to driving your speakers effectively, but with so many available power amp options, what one do you choose?
For those new to power amps, the most important factors to consider are how many channels you need, compatible wattage and ohms, what connections you need, and if you want extra features, like DSP, Ethernet, or power-saving capabilities. Power amps also come in different power classifications, like Class D or Class H. Rather than measuring the quality of the amp’s sound, these classifications denote different circuitry designs, and you may find that you prefer one over the other. At Sweetwater, we want you to have the best amplifier for your application. That’s why we compiled a list of some of the best power amplifiers for live sound right here! These powerful, popular, and high-quality power amps cater to various requirements and budgets, so we know you’ll find the perfect match.
