This machine uses Wolfson Microelectronics that enjoyed a high reputation in the audio industry high performance:top decoding chip WM8741.This chip has high signal to noise ratio and isolation, so that the music details such as silk smooth, fine finish now.
DAC_M has three input choices：
Optical input uses a 3.5mm interface, using the random distribution of optical fiber line Unicom source fiber output.
In the playing ,please don't pull the fiber line, so as to avoid the loss of synchronization of digital audio signal generated noise.
This machine adopts the coaxial Mini socket, use rationing coaxial and audio RCA coaxial base connection.Coaxial input support 192Khz 24Bit sampling rate ( fiber and USB are not supported).
Use USB cable and PC butt joint, if the PC is WIN 7 can automatically identify switch; if XP system will close the sound card, select "USB AUDIO " equipment.
