Editor's note: this is the final installment in this series. Part one is available at http://www.audiodesignline.com/howto/199202502 At 15 dB to 12 dB even very dense ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...

The final amplifier is the power source of every audio installation. Its job is to convert a small alternating voltage into a powerful signal for driving loudspeakers with as little distortion as ...

Operating noise free, the NCP2991 1.35W class AB audio amplifier specifies a power-supply rejection ratio of -103 dB. Groomed for portable and wireless audio applications, the device guarantees zero ...

The most common audio power amplifier operates in the Class-AB mode. It provides the greatest amount of output power with the least amount of distortion. The downside is that it consumes quite a bit ...

Analog amplifiers are cataloged by how much current flows during each wave cycle. Measured in degrees, 360º means current flows 100% of the time. The more current, the more inefficient and the more ...

Meylan, France - February 4, 2008 - The pressure to lowering the power consumption leads system designers to investigate different architectures for audio amplifiers. They naturally investigate ...

The new Model 7220 Amplifier is a class AB, fully balanced design. It delivers 220W per channel into an 8-ohm load with all seven channels driven and 330 watts per channel into 4 ohms (assuming ...

[Dino Segovis] wrote in to tell us about his “hack”, making an AB Audio Amplifier. The advantage of this particular amp is that the transistors never turn off, which would cause distortion. A full ...
