Advantages:
- PCM1794A chip: It boasts a sampling rate of 24bit192K, a high resolution, a sense of speed and transparency, and the tri-band is very commendable, especially the human voice, which is round and sweet. It is a cost-effective chip. After 2pcs PCM1794A are connected in parallel, the dynamic range and signal-to-noise ratio are greatly improved to 132dB. After the parallel connection, the output current is doubled, the sound density is enhanced, the human voice is obviously thick, the whole sound section is relatively balanced and friendly to ears, and the low frequency is also enhanced. The signal-to-noise ratio is improved, so the background looks cleaner
- Parallel enhancement: After PCM1794A is connected in parallel, the dynamic range and signal-to-noise ratio are greatly improved. The sound is more pleasant and the sound density is also enhanced
- Balanced line: One PCM1794A chip is only responsible for one channel, and the independent lines are truly balanced. The two channels do not interfere with each other, the sound is crisp and warm, clean and transparent, with good resolution

Parameters:
- PCB Size: 10.4 x 8.25mm (LxW)
- Digital power supply: 5V DC
- Analog power supply: ±12V DC
- Input type: I2S
- Sampling rate: 24Bit, 192kHz
- Output type: balanced output, single-ended output
