The system uses a pure, extremely low ripple (full load ripple less than 100ppm) high-efficiency switching power supply, under the premise of ensuring ample power reserve and almost zero interference to the audio, it meets the European energy consumption requirements (standby power consumption is less than 0.5 W)
The system is equipped with two sets of analog inputs, one of which is professionally used for balanced input interfaces, and the other is for cable RCA interfaces. The balanced input signal enters the digital system through the high-quality analog-to-digital conversion chip PCM1804 with differential input. The chip has a dynamic range of up to 112dB and a signal-to-noise ratio of 111dB. The maximum working sampling rate reaches 192kHz, ensuring that the auxiliary input signal is undamaged.
The system is equipped with two digital inputs, one is Toslink optical interface, the other is coaxial interface. The digital interface front end uses Texas Instruments PCM9211, which supports input signal sampling rates up to 216kHz.
A200 uses the CSR8645 chipset and built-in APT-X decoder to optimize the audio signal damage caused by the encoding and decoding of BT music transmission, so that BT audio is no longer of low quality. Use rail-to-rail low-noise operational amplifier to ensure that there is no loss of output signal
