Feature

1 Bluetooth receiver based on CSR64215, the real 4.2 module, support APTX, transmission distance, signal loss.
2 ES9023 independent decoding, Take the I2S protocol transmission,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 WIMA, the board with dual active independent crystal, Foxconn headphone jack and so on.
3.5 stereo output can connect headphones, can also connect active speakers and power amplifier.
