Description: -The main chip uses HIFI grade PCM2704 USB decoder chip, its performance is better than the market commonly used low-end chip CM102S series, power supply using USB power supply, the output can be directly connected to the headset, but also to do the forefront of digital output can be more DAC decoder to provide SPDIF digital signal to get better sound quality. -As a result of external sound card, to avoid the chassis of the serious electromagnetic interference, signal to noise ratio and sound quality can be improved. -PCM2704 is a monolithic analog-to-digital converter chip. It has two digital-to-analog output channels and an integrated USB interface controller. The interface conforms to the USB 1.1 standard. PCM2704 can receive 48KHz, 44KHz and 32KHz sampling rate of 16-bit stereo or mono audio data, chip integrated software volume and mute function, you can adjust the computer's volume and mute.
