Description:
This decoder board adopts HIFI level PCM2704 USB decoder chip, its performance is better than the CM102S series, which is the most popular chip on the market. The USB power output can be connected directly to the headset, but the pre-digital output for more advanced DAC decoder also provides SPDIF digital signal to improve sound quality. Because this is an external sound card, the chassis can avoid serious electromagnetic interference, which can improve SNR and sound quality.
PCM2704 is a single chip digital analog converter chip. It has two DAC output channels and integrated USB interface controller. The interface complies with the USB 1.1 standard. PCM2704 can receive 48KHz, 44KHz, 32KHz sampling rate, 16-bit stereo or mono audio data. Sync volume and mute function on internal software chip, adjust volume and mute computer.
