Hi-fi stereo audio amplifier.
Twin circuit Class A/B audio amplifier: Two completely independent circuits, from power supply to the output stage, to ensure a responsive and truthful stereo amplification.
Key specs:
Output: 2 x 25 watts (RMS)
Gain = 50.
low distortion (less than 0.5%)
low noise (less than 0.5%)
Relevance
I built audio amplifiers with the manufacturing process of high-precision circuits, from design to manufacturing, with the challenge of delivering accuracy of industry standards for high-gain circuits: noise and distortion of less than 0.5%.
Some thoughts:
To reach high precision electronics is necessary to address multiple areas as: signal processing, interference, amplification, signal conditioning, noise control, quality manufacture. However , the importance of stable and clean power source to achieve repeatable results and trustworthy measurements, had a special role.
Modular design eases scalability and the quality control process (pinpoint where the noise or distortion is being generated).
