USB DAC USB To SPDIF Sound Card Analog Output Decoder Board

Feature:

The USB input, coaxial, optical fiber and analog output. The board comes with volume and mute control. The main chip is uses BB company HIFI level PCM2704 USB decoding chip, its performance is superior to the most commonly used on the market of low-end microchip CM102S series. Power is supplied by USB, the output can be directly connected to headphones, also can do the front-end. In order to get a better sound quality, digital output provide SPDIF digital signal for more advanced DAC decoder. Because it is a external sound card, to avoid the serious electromagnetic interference inside the case, the signal-to-noise ratio and quality has improved. PCM2704 is a monolithic analog-to-digital conversion chip. It has two analog conversion output channel and one integrated USB interface controller. The interface is in conformity with USB1.1 standards. PCM2704 can receive 44 KHZ and 48 KHZ, 32 KHZ sampling rate of 16 bit stereo or mono audio data, volume and mute function of internal integration chip, and can adjust the volume of the computer and synchronous mute.
