Most audiophiles and enthusiasts have grown up with at least a basic understanding of what an amplifier does. It takes a tiny alternating electrical signal that represents the moment-to-moment ...

1. Is Amplifier Weight an Indicator of Robust Amplifier Design? You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before you can generalize about weight ...

2x 500W in 2 Ohm BTL at 50V or in 4 Ohm BTL at 70V, with 97% efficiency 1x 1000W in 1 Ohm PBTL at 50V or in 2 Ohm PBTL at 70V, with 98% efficiency Less than 3W of total idle losses for the GaN power ...

If you already know about class A, B, and AB, they are all linear amplifiers with constant gain where the audio is fed to the base of a transistor. The latest class D audio amplifier is switch type ...

A class-D puts out a pulse-width modulated (PWM) signal instead of the typical class-AB amplifiers linear signal The PWM signal contains the audio signal and the PWM switching frequency plus harmonics ...
