CSR8675 Bluetooth 5.0 APTX HD hifi amplifier Decoder Module
CSR8675 bluetooth 5.0 aptx HD DAC bluetooth receiver supports analog input output, supports not only aptx, but also APTX-HD.
Many people need to add Bluetooth function for the amplifier, but a Bluetooth board can not solve the problem, because the amplifier itself has analog input. The board is a good solution to the problem. Added the analog input port, when the mobile phone Bluetooth connected, the amplifier output the Bluetooth audio of the phone. mobile phone Bluetooth disconnect, automatic connection will be the original analog input.
PCB Size: 64x63mm
Voltage input range: AC 6-12V, or DC 7-15V
- Bluetooth receiver based on CSR most * * High-end solution CSR8675, Real 5.0 module, support APTX HD transmission distance, signal lossless

Bluetooth "guardian angel"--aptx® Technology was born! It decodes the audio to be transmitted, significantly reducing the bit rate, without affecting the sound quality, also does not bring the transmission delay problem, so that the Bluetooth stereo listening experience. With Aptx, you can enjoy the pure wireless sound effects of CD-level quality anytime and anywhere.
At the same time through ES9023 (or PCM5102) decoding further improve the sound quality and analytical power.
The advantage of ATPX HD aptx is that it can play 16-bit/44.1khz audio in the way it transmits music. But because Aptx uses the compression method to reduce the audio coding delay, it can only bring "CD-like Quality".
The advent of Aptx HD is related to the popularity of high-definition audio, which can support up to 24-bit audio, which means we will be able to use wireless devices to hear better quality music. Compared to the traditional aptx 352kbps ratio, the aptx HD increase to 576kbps bit rate is undoubtedly more advantageous.
