The literature on power amplifiers frequently discusses the importance of power-supply rejection in audio amplifiers, particularly in reference to its possible effects on distortion [4]! I have (I ...

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 ...

Samsung’s 2025 Q-series soundbars, including the HW-Q990F and HW-QS700F, feature AI Sound Optimisation, Dynamic Bass Control, and Active Voice Amplifier Pro for enhanced audio. They include a ...

A relatively new technology called the pure digital or Class-D amplifier has been introduced into the audio world. The Class-D architecture allows the input audio signal to stay in its digital format ...

We uncovered an audio myth on our YouTube channel I didn’t even know was being perpetuated by some esoteric amplifier companies. Apparently there is a belief that designing an amplifier to be too ...

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 ...

Join [Jørgen Kragh Jakobsen], Analog/digital Design Engineer at Merus-Audio, for this week’s Hack Chat. Every week, we find a few interesting people making the things that make the things that make ...
