BU2 conducts targeted tuning according to the characteristics of Bluetooth, so that Bluetooth can be so beautiful. After the desktop computer or MacBook is connected to BU2 through USB, it can directly reach the 32bit/768k DSD512 master band decoding ability, so that the computer can show the live hd music.
Dual core decoding chip,four independent Headphone Amplifiers
BU2 adopts the low ripple positive and negative power supply circuit of the classic Bi pump power supply to provide continuous power for the earphone. ES918*2 decode in parallel and add four independent headphone amplifiers
Clock synchronization technology
The BU2 uses two low jitter 45M/49M crystals and is synchronized to the two decoding chips through USB chips. The sound is natural, delicate and durable.
R2R dynamic volume technology
Bu2 innovatively adopts the dynamic volume control technology composed of electronic switch and R2R resistor. The R2R resistor array intervenes at low volume to control the fine volume with accurately matched resistance. The SNR Is excellent, the sound source is dynamic and the details are not smeared
Low Noise, Low Distortion
Carefully designed and optimized for many times, the bottom noise of bu2 is as low as 3.l6uv and thd + n Is as low as 0.000145%. It is a balanced decoding earphone with excellent indicators.
