[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 succeed in 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 far better and more natural with lower distortion and lower noise.
Top of the range components are used to recuperate performance, such as tantalum capacitors, WIMA capacitors, American DALE non-inductive resistors, digital shaping chip, digital transformer, gold-plated RCA terminals and so on. Powered by DC 5V and filtered by CLC circuit, with lower power ripple and more delicate music.
Mini size with attractive design, aluminum alloy shell for better shielding performance. With power and digital/analog output switch, even can save output selection after shutdown, red/green/blue colorful indicators can clearly show the working status, very convenient to make use of.
Warm tips: powered by DC 5V (micro-USB), equipped with USB cable but no power adapter, you’ll use your phone charger.
