Hardware:
- MA12070 is an ultra-efficient audio power amplifier chip based on proprietary multi-level switching technology. With embedded digital power management scheme, the efficiency is as high as 92%. Use algorithms to dynamically adjust frequency and optimize power loss. At the same time, it can against direct current, short-circuit, overheating and under-voltage. Optimized the power consumption during music playing, so that it has lower power consumption. A compact, highly integrated solution that truly achieves high power and small size. High-definition sound quality and powerful audio performance-high dynamic range, low distortion, and low noise.
- ES9023 decoder chip: With architecture for Hyperstream and time-domain jitter canceller, 2Vrms 24bit chip with integrated operational amplifier can provide 112dB DNR jitter-free studio quality audio.
- NJW1194 volume control: 2-channel electronic volume controller. Thanks to resistance ladder-shaped electronic potentiometers, it has the characteristics of low offset and low output noise.
- Audio dedicated capacitor series. The sound bottom is clean and neat, the level is good, the low frequency is compact, and the high frequency is penetrating.
- Bluetooth module. Mature Bluetooth receiving solution, support for Bluetooth 5.0, apt-X.
