<b> SMSL M500 DAC Headphone Amplifier DSD512 HiFi USB/Coaxial/Optical Audio Decoder Analog-to-Digital Converters</b> <br><br><b>SMSL M500 DAC Product Features:</b> <br> Combined with ES9311,it reduces the power supply noise to 1uVrms. <br> XMOS XU-216+DSD512+PCM768kHz <br> All input support DSD transmission. Coaxial and optical supports DoP64. <br> The volume design of independent headphones does not interfere with the volume of preamp. <br>Tempered glass display panel brings higher light transmittance and longer service life. <br>Built-in shielding, low noise power supply processing, at the same time improving the efficiency of power supply, lower power consumption. <br><br><b>Product parameters:</b> <br><br>Input: USB/Optical x 2 / Coaxial <br>Output: RCA Headphone Amplifier/RCA/XLR <br>THD+N: 0.0002 % <br>Dynamic range: XLR 125dB; RCA 120dB <br>SNR: 120dB <br>USB transmission: Asynchroniazation <br>USB compatibility: Windows 7/8/8.1/10, MAC OSX10.6 or Later、Linux <br><br>Bit depth: <br>USB: 1bit, 16~24bit <br>Optical / Coaxial: 1bit, 16~24bit <br><br>Sampling rate <br>USB PCM 44.1~768kHz <br>DSD 2.8224~22.5792MHz <br>Optical / Coaxial PCM 44.1~192kHz <br>DSD : DSD64(DoP) <br>Headphone amplifier output power: 570mW (32Ω）; 290mW (64Ω）; 125mW (150Ω）; 65mW (300Ω） <br>Power Consumption: 5W <br>Standby power: 0.6W <br>Size: 85 x 88x 197mm( W x H x D) <br>Weight: 0.91KG
