OLED screen display to reach music information. CSR8675 Bluetooth chip support SBC, AAC, aptX HD, LDAC, and other audio formats. Utilizes high-performance CS8406 as digital output conversion chip to get high output signals in Coaxial/Optical. Up-frequency function, up to 24Bit/192kHz, which makes the sound more delicate. ES9038Q2M decoding chip, for clear and high-resolution analog signals. With high-quality digital/analog output, it can be connected to any power amplifier/speaker. The customized EI transformer is used as the power supply system, which has more stable performance and lower noise. Use the NICHICON capacitor at a high level as the main filter capacitor, which sounds compliant and transparent. The outer shell is made of CNC. The Bluetooth antenna with external high gain can transmit a longer distance and a stable signal.
