Model No: WHFBR-A4490HD
This is a Bluetooth decoder with Bluetooth 5.0 CSR8675 and DAC AK4490. The Bluetooth 5.0 version CSR8675 implemented digital signal transmission thought wireless function, the digital to analog conversion of audio output used a professional decoder chip AK4490 to play that the digital signal is decoded into an analog audio signal, and finally OP amplified the analog audio signal and output it.
Currently, the sound quality of CSR8675 is one of the most stable, best Bluetooth chip, supports APT-X, APTX-HD, APTX-LL transmission.
AK4490 is a new generation Premium 32-bit 2ch DAC with new technologies, achieving industry’s leading level low distortion characteristics and wide dynamic range. The AK4490 integrates a newly developed switched capacitor filter “OSR Doubler”, making it capable of supporting wide range signals and achieving low out-of-band noise while realizing low power consumption. Moreover, the AK4490 has five types of 32-bit digital filters, realizing simple and flexible sound tuning in wide range of applications.
