SMAKN® Mini PCM2704 USB Sound Card DAC Decoder Board
PCM2704 USB sound card/DAC, The USB input, coaxial, optical fiber, analog output. BB company is used in the main chip level HIFI PCM2704 USB decoding chip, its performance is superior to the most commonly used on the market of low-end microchip CM102S series, power supply, power is supplied by USB output can be directly connect headphones, also can do the front-end. Digital output to provide more advanced DAC decoder SPDIF digital signal, in order to get a better sound quality. Because it is the external sound card, to avoid the serious electromagnetic interference inside the case, the signal-to-noise ratio and quality 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.
USB support sampling rate: 16 bit / 32-48 KHZ USB support system: WINXP/Windows 7 / doing, apple’s MAC OS 9 / OS X, the android 4.1 + system model (need to support OTG) Photos are for reference only, the terminal color in kind prevail.
