Modular High End Audio Amplifier System

Modular audio amplifier system

Project road map and presentation of my year 2020 audio project: The modular high end audio amplifier system. A highly flexible audio amplifier that can be configured in many ways based on a variety of different modules.

High End Audio Amplifier System Modules

Collection of all modules that are available for the modular audio amplifier system, including pre-amplifiers, front-ends, driver stages, output stages, power supplies, control and protection modules.

Amplifier Input Protection

In this article I compare various options to protect audio amplifier inputs from ESD and excess voltage in general in order to find a circuit that offers very good protection, maintains excellent audio signal quality and is easy and safe to implement in various amplifier designs.

Current sources for audio amplifiers

I investigated different current sources to find out which one performs best in terms of PSRR, step response and thermal stability.

Amplifier output stage comparison

I compared the triple emitter follower with a variant of the Diamond buffer in order to find out which one performs better and why Diamond buffers are not used as power output stages more often.

3D CAD models

3D CAD models

I created some 3D CAD models that I share on 3DCONTENTCENTRAL. Most of those CAD models represent electronic components to be used for designing electronic assemblies. Since virtually every electronic assembly interfaces with mechanical parts, like enclosures, having a realistic physical representation of the electronic assembly ensures that everything fits together well and the project is successful. My projects profit from using shared models and this is why I like to share mine as well.
