["Feature:\r\nSupports coaxial SPDIF output\r\nCan be connected to the phone OTG\r\nSupport I2S output can be external decoder\r\nThe internal includes the ES9023 independently decode audio output\r\nUsing CM6631A, more cost than the CM6631 chip, better performance\r\nCompatible more stable. By the professional PCB full post, precision parts design. All using posts active low temperature\r\nCM6631 support playback feedback endpoint to control the accuracy of data transmission, that is, asynchronous USB. Details and analysis,are beyond reproach\r\nCmedia CM6631 is the world's first USB2.0 real high-speed audio processor,can support the latest USB audio device class definition V2.0 and high-definition audio processing capacity up to 192KHz / 32bit,maximum support 32BIT\r\nWith USB to coaxial output interface,support asynchronous 24BIT192K only output,can be used to upgrade the external DAC.for WINXP WIN7 WIN8 32BIT and 64BIT system.Support DTS and other source output\r\n\r\nSpecifications:\r\nVoltage:5V\r\nOutput 1:audio input,with ES9023 high-precision decoding IC,with internal drive circuit thrust\r\nOutput 2:I2S output, can be connected to other DA equipment\r\nOutput 3:SPDIF output! That is, coaxial output\r\nSize:10.6x7x2.5cm/4.17x2.76x0.98inch\r\nNote:\r\nPlease allow 1-3mm error due to manual measurement.pls make sure you do not mind before you bid.\r\nDue to the difference between different monitors,the picture may not reflect the actual color of the item.Thank you!\r\n\r\nPackage Includes:\r\n1x CM6631A Board"]
