Functional introduction:

1. Volume control via I2C interface is a great feature to keep the great audio quality with various audio output volume.
2. The output ports include gold-plated stereo RCA terminals
3. An ultra-low noise dropout regulator is populated for the power supply, significantly reducing power supply noise and greatly increasing the signal to noise ratio.

The I2S interface allows for direct decoding of the digital input to analog output using master clock synchronization


5. The PCB surface is comprised of gold-plating on top of 2 oz. of copper, ensuring signal continuity and reducing signal reflection and refraction.
6. Balanced(differential signal) audio output soldering pads are available.

The dedicated S/PDIF interface is newly added which supports up to 192kHz/24bit resolution via new Optical (Toslink) output.
