What does amplifier efficiency mean?

What does amplifier efficiency mean? All amplifiers have a certain predictable level of efficiency, and most class A/B amplifiers are between 20% to 60% efficient. That means that of all the power coming into the amplifier, 20% to 60% of that power is turned into sound and the other 80% to 40% is turned into heat. Simply put, the higher the efficiency rating of an amplifier, the more power the amp will make and the less heat it will generate overall. While having a 100% efficient amplifier would be great, it is physically impossible to make an amplifier that loses nothing when making power.

The efficiency rating on the Punch Verification Certificate we print for each amplifier we make simply shows how efficient our amplifier is at the test voltage, and what kind of power that amplifier will really make with that amount of voltage coming in.

If you're looking for the utmost in efficiency, our new Power "bd", Power "tm", and Punch "br" technologies have been known to be 75% to 80% efficient!
