About this item:
- Warm tips: powered by DC 5V (micro-USB), equipped with USB cable but no power adapter, you can use your phone charger.
- [Fully upgrade version in 2021] As a stereo audio receiver, Bluetooth input with strong compatibility, and with digital (coaxial & fiber optical) and analog (stereo L/R RCA) output, very suitable to work with the digital amplifiers, active speakers and other audio devices only with coaxial and optical inputs.
- Adopting CSR8675 Bluetooth chip, supports APTX-HD to achieve faster and more stable transmission, adopts I2S signal output and decoded by TI's DAC chip PCM5102A with multi-level LDO voltage stabilization, the sound quality is much better and more natural with lower distortion and lower noise.
- High-quality components are used to get better performance, such as tantalum capacitors, WIMA capacitors, American DALE non-inductive resistors, digital shaping chip, digital transformer, gold-plated RCA terminals etc. Powered by DC 5V and filtered by CLC circuit, with lower power ripple and more delicate music.
