We engineer audio systems, from silicon to firmware.
Audio Electrons is Protechgroup Engineering's division dedicated to the design of electronic audio systems. Sophisticated circuit solutions for signal conditioning and power amplification, paired with advanced DSP algorithms, for sound that's increasingly smart.
A Protechgroup division dedicated to sound
The Audio Electrons team has been designing and building electronics for audio signal processing and amplification for over twenty years, in both analog and digital technology, with close attention to sound fidelity. We combine hardware competence with firmware expertise, to build complete audio systems, from concept to production.

Hardware and firmware, under one roof
Two disciplines that usually live in separate teams, integrated into a single design process.
Audio electronics design
Analog amplification circuits, Class D power stages, power supply, protection and PCB layout optimised for noise, EMI and reliability.
- Sound measurement instruments and systems
- Linear amplifiers (Class A/AB)
- Switching amplification (Class D)
- Power supply and thermal management
- Custom circuit solutions
- PCB layout and EMC compliance
Firmware applications and audio algorithms
Embedded firmware and DSP algorithm development for real-time signal processing: filters, crossovers, limiters, tuning and digital audio protocols.
- Real-time DSP processing
- Embedded firmware (bare-metal / RTOS)
- Digital audio protocols (I2S, TDM, SPDIF)
- Research and development of custom processing algorithms
- FFT and frequency-domain processing
Where Audio Electrons works
Our hardware and firmware expertise applies across several professional and consumer audio sectors.
