Feiteng Cloud XMOS USB HiFi Sound Card Solution

Nowadays, more and more consumers are dissatisfied with the quality of built-in audio output of old computers or mobile devices, and hope to get a higher quality audio experience through external devices. At the same time, with the popularity of high-resolution audio formats such as PCM up to 32-bit/384kHz and DSD, audio accessories with high-performance DAC and corresponding processing capabilities are needed to support the decoding and playback of these formats. In professional audio fields such as music editing, music production and professional recording, high-fidelity audio output is also a must. When people are running or traveling, they also hope to be able to listen to high-end audio quality anytime and anywhere. Feitengyun XMOS USB HiFi sound card came into being.

Feitengyun XMOS USB HiFi sound card solution is a product designed to improve the audio output quality of computers or mobile devices. It connects to a computer or other digital audio source via a USB interface, providing higher audio resolution and sound quality than built-in audio processors. The following are the main features and working principles of Feitengyun XMOS USB HiFi sound card solution:

Key Features:

1. High-resolution audio support: Supports high-resolution audio formats such as PCM up to 32-bit/384kHz and DSD audio formats to restore more music details.

2. Low Noise and Distortion: Built-in high-performance digital-to-analog converter (DAC) and low-noise amplifier (AMP) provide clear, low-distortion audio output.

3. Flexible interfaces: Includes multiple input and output interfaces, such as 3.5mm headphone jack, RCA line output, optical or coaxial digital input, etc., to meet the needs of different devices and scenarios.

Working principle:

• Digital audio transmission: The USB interface serves as a channel for data transmission and receives digital audio signals from a computer or other digital audio sources.

• Audio Processing: The received digital audio signal is decoded and processed, including decoding PCM or DSD format, performing necessary sampling rate conversion and digital signal processing.

• Analog Output: The processed audio signal is converted to an analog signal through the built-in DAC and then amplified by the built-in amplifier to a level sufficient to drive headphones or speakers.

• Output Interface: Final audio output is sent through various interfaces on the device to connect headphones, speakers or other audio devices.

Technical Specifications:

• Supports PCM sampling rates up to 768KHz

• DSD 512 audio decoding

• USB UAC2.0 protocol asynchronous transmission of high-definition bit rate audio
