CCIF and DIM30 measurements added to Engine-400 specification sheet

Measuring amplifier THD at 1kHz and 6,67kHz does not reveal all non linearities. Depending on how the structure has been designed there could be other artefacts that can only be revealed with more advanced test signals. CCIF is a twin tone measurement where the difference is measured, usually between 18kHz and 19kHz i.e. at 1kHz. […]

Datasheets released for Engine-400 and Motherboard-1

Finally, we have the pleasure to release datasheets for Engine-400 and Motherboard with AUX-plant coming very soon. We had to make some final changes to the design and it is now even better than before. The inductor is now what is called a helicoil or edge wound copper spiral which has decreased the idle losses […]

Motherboard-1

Check out the typical implementation for a two channel amplifier using Audio bricks Engine-400 and AUX-plant. It shows how to build start up control, supply voltage supervision and thermal protection. It also contains buffers for increasing the common mode impedance when using longer cables and electrolytic storage capacitors. If you want to build external control […]

What is the reason for classd?

What is the meaning of classd amplification? We all know the answer, it is the increased efficiency which allows us to make smaller amplifiers which consume less energy. The challenges when designing a switching amplifier are tremendous compared to designing a linear amplifier. A major distortion contributor is usually the transition time variation which causes […]
