Description
Prometheus Audio Decoder HiFi Lossless Digital Analog Converter Streaming Digital Audio Player with 3.12-inch OLED
Features:
- ES9038Q2M decoding chip: The dynamic range of ES9038Q2M can reach 129dB, and the frequency response range is wide (20Hz-20kHz).
- Support up to 32-bit/768kHz PCM and DSD512, compatible with high-resolution audio files on the market.
- Imported surface mounted active crystal oscillators provide highly accurate clock signals, greatly improving system stability and performance. With low noise characteristics, they can effectively reduce clock noise interference, ensure high fidelity transmission of audio signals, and enhance sound quality performance.
- Self-developed programmable gate array architecture for FPGA, proprietary logic function digital integrated circuit, clock management, 2nd PLL digital shaping DOP demodulation, PCM/DSD depop switch and other exclusive technologies.
- Super parallel processing, flash kill delay, multitasking simultaneously, greatly improving audio decoding speed.
- Unique hardware acceleration makes audio processing more precise and fast, presenting richer and more delicate sound quality details.
- Ultra precise clock synchronization technology seamlessly connects multi-channel audio data, avoiding clock errors and enhancing the natural reproduction and layering of audio.
- Imported large capacitor matrix, effectively smoothing power output, reducing voltage fluctuations and noise.
- It can greatly reduce high-frequency noise and pulse interference in the power supply, and improve the overall working environment of the equipment.
- Our self-developed audio dedicated ring transformer power supply features low-noise design and optimized electromagnetic interference (EMI) protection to reduce power supply noise and interference, providing clearer and purer current output.
- The STM32F446 adopts for ARM Cortex-M4 core, which has ultra-high computing power to efficiently process complex audio encoding and decoding algorithms. It integrates proprietary USB audio protocol and can interface with various audio devices, supporting multiple audio sampling rates and different audio formats.
