Linux, delphi system are no need for driverbut requires external power supply and switch the panel switch to USB. External power connector: DC3.5-1.3MM/5V. (The voltage must be 5V, if over it the deivce will be burned).
Coaxial, Optical working current: 60mA. USB input working current: 200mA. Headphone power: 130MW / 32? Audio output THD: 0.008%.
USB support: PCM44.1K-384K/32Bit, DSD64-DSD256. Automatic identification decoding and n. USB support system: OTG Andriod Mobile.Apple PC, Linux, system don't need the driver. Size: 1109825mm (Not include the connector part). 1× USB to 3.5mm power cable.
Note: When DAC Only with Optical input (Opt), no matter the switch at Coaxial or optical place the signal is optical signal, Once plug the coaxial cable then you can select the matching decoding way. If the DAC only with Optical input signal, no matter the selector switch at Coaxial or optical position it just the optical signal, once insert the coaxial cable then have to select the matching input signal, that not the device quality problem, it is just the DAC preferred signal mode. DAC not support DXD format. USB Port to Mobile, need add the external power supply.
If the device has a fast forward and no sound problem , that caused by the USB Contact or power supply , just inert the cable or change USB port is fine. This device Line Out output signal is a little weak, so when connecting it to amplifier should adjust the volume higher. When using the headphone output, please don't keep close to the mobile or router, it will get the interference and cause noise, if connect the device to mobile we recommend that download the music and set the mobile as Flight Mode (Don't entangled with this problem, the thousands dollars SONY series of PHA has this same kind of situation).USB sound card can't be identified, after connecting but the indicator not glow, the problem may be caused by USB Poor contact or external power not enough, please check the USB cable or make sure your power supply voltage is 5V. The device can't be connected to the PC front USB port , it easy cause the papapa noise. Telephone number, correct address, input voltage, color, etc..
