Product features:

1. Use the popular asynchronous USB audio decoding scheme - XMOS xu208 chip

2. With the DSD special interpretation chip dsd1796 of Ti of the United States, 384k PCM and dsd64-dsd256 format signals are directly decoded in hardware, and the master band audio is enjoyed

3. Built in high fidelity earphone, large thrust, good low-frequency response, and the actual feeling of low-frequency surging!

4. USB interface supports OTG Android phones, set-top boxes, Apple computers, iPads and iPhones

5. The sound card supports windows system (you need to install drivers to use), MAC, Linux (these two operating systems do not need drivers), mobile devices, mobile phones and tablets

6. Add coaxial, optical fiber and Bluetooth input decoding functions, which can be connected to TV, DVD, set-top box, mobile phone, etc., which is convenient for external audio and can significantly improve the sound effect!

7. Multi stage precision ultra-low ripple voltage stabilizing chip, plus components for fever level sound (Sanyo solid state, tantalum capacitor filter, Japan Elna red audio capacitor), is the guarantee of good sound.

8. The built-in high-capacity polymer battery is convenient for carrying or vehicle use. The life of Bluetooth mode is 15 hours, and that of coaxial and optical fiber decoding is 40 hours!

9. The new model supports the replacement of operational amplifiers, which can be replaced freely (Note: all three operational amplifiers are dual operational amplifiers), and the default is ne5532
