CSR64215 Bluetooth 4.2 Decode Board DAC ES9023 I2S Decoding HIFI AD823 APTX for Earphone Amplifer active Speaker DIY

Specification:
- Brand:GHXAMP    
- This is the finished board, power supply can be used mobile phone charger or computer USB cable, very convenient
 
Highlights:
1 Bluetooth receiver based on CSR ** ** high-end program CSR64215, the real 4.2 module, support APTX, transmission distance, signal loss, the use of active crystal to provide more sophisticated clock signal
2 ES9023 independent decoding, take the I2S protocol transmission, no decoding output than the Bluetooth playback board sound better, the decoder level details are very good, dynamic large, not the general level of Bluetooth audio output comparable distortion: THD + N : <0.006%
3 In order to have a lower output impedance and good matching output using HIFI op amp AD823, this IC is used on the Rainbow C4, showing its excellent quality
4 with resistance is very good, N'ikon FW audio capacitors, P'anasonic FC high-speed filtering, the German red W'IMA, the board using dual active independent crystal, F'oxconn headphone jack and so on.
 
PCB Size: 61X60MM
 
Power supply :5V (phone mobile or PC usb power,)
 
Decoding part :
1.Decoding part of the latest US ESS9023 top decoding core, ES9023 is ESS's 24bit stereo audio digital-to-analog converter chip (DAC),
2.using the industry's advanced SABRE digital-analog conversion technology, this chip set the best sound quality, cost-effective In one, making it an ideal choice for digital-to-analog conversion. ES9023 internal use of patented technology Hyper-flow (Hyperstream) architecture and time-domain jitter elimination technology, so that it can achieve jitter-free recording level of sound quality, dynamic range of 112dB.
