Power Amplifiers

What is a power amplifier used for?

A power amplifier boosts the voltage and current of a line-level signal in order to drive passive loudspeakers, stage wedges, or studio monitors.

How do power amplifiers work?

A power amplifier converts a weak input signal, like the low current coming from a mixing board or preamp, into a more powerful signal that’s capable of moving the drivers inside your loudspeakers.

What are the different classes of power amplifiers?

Power amps fall into different classes, each with its own strengths. Class D power amps, for example, are known for their efficiency and resistance to overheating, making them a popular choice for touring and live sound rigs.
