Product introduction:

The main chip uses BB's HIFI -level PCM2704 USB decoding chip. Its performance is better than the most commonly used low -end chip CM102S series in the market. The power supply uses USB power supply.The higher -level DAC decoder provides SPDIF digital signals to get better sound quality. Because it is an external sound card, it avoids the severe electromagnetic interference in the chassis, and the signal -to -noise ratio and sound quality can be improved.
PCM2704 is a single -chip digital mold conversion chip.It has two digital modular conversion output channels and an integrated USB interface controller.The interface meets the USB1.1 standard.PCM2704 can receive 16 -bit stereo or monocular audio data of 48kHz, 44kHz, and 32kHz sampling rates. The internal integrated software volume and mute function of the chip can be synchronized to adjust the volume and mute of the computer.
