This is our Douk Audio Studio Upgraded version Mini USB DAC & HiFi Headphone Amplifier, with coaxial, optical digital input, which is very convenient to connect speakers to improve the sound effects. 
This sound card with USB connector ,very convinent to PC/Notebook,super mini and portable design.

Using TI’S high-performance DSD1796 as the decoding chip(DSD Professional decoding chip,The lowest distortion is 0.0005% ) XMOS U208 as the USB part,with MCU control, automatically decoding DSD/PCM ,automatically transfer indicator light (DSD/PCM indicator) 3Set input decoding ,with coaxial 、headphone、linear output. It can play PCM、DSD64、DSD128、(native DSD256 ) Format music.


1.Sound effect and the Low frequency dynamic beyond previous XMOS Edition

2.Convinent to switch the input mode

3.Decreasing the DSD, PCM playing convert impact sound

4.Headphone amplifier add the Volum control function

5.When decoding via USB it Support DSD Native mode,Details and sound field much more better

6.The latest breakthrough in USB audio decoding technology: XMOS XU208 asynchronous transmission, brings the signal transfer fidelity to a new height.

7.Texas Instrument top-performing DSD1796 decoding chip support both 384K PCM and DSD64-DSD256 formats, which allows you to enjoy mastering quality sound conversion.
8.Built-in high-fidelity headphone ,Strong power source, low frequency response
9.Support External power supply ,it can be powered by power bank or other USB Device like the TV BOX ,TV
10.USB Support OTG Android mobile /Android TV box /linux don’t need the driver (need the external power and set the input mode as USB ),We recommend mobile install the APP “haibyMusic”to support DSD format

  • 1× USB Cable
  • 1× USB to 3.5mm power cable
  • 1× Driver CD

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.

Details Show:

1. Power supply select switch,to EXT is External power supply ,to USB is powered by USB

2. Decoding input select switch,3 option

3. 3.5mm headphone ouput (Suit 16-250Ω)

4. Headphone output volume control

5. Linear output, connect to amplifier or headphone amplifier or other device

6. Optical IN: Optical digital signal input port ,Sampling rate :44.1-96k ,16-24bit

7. SPDIF IN: coaxial digital input port ,standard level 0.5v,Sampling rate :44.1-192k(16-24bit)

8. USB IN: Using the USB2.0 digital cable to computer USB Port, Pls using the Double magnetic ring cable to avoid the noise.

9. DC IN: Connect the External power ,it must be 5V Current >0.5A ,PLS note the power polarity.

Precautions for use:

1. 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 coacial cable then have to select the matching input signal ,that not the device quality problem ,it is just the DAC Preferred signal mode issue.

2. DAC not support DXD format

3. USB Port to Mobile ,need add the external power supply

4. 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 .

5. This device Line Out output signal is a little weak,so when connecting it to amplifier should adjust the volume higher

6. When using the headphone ,pls don’t keep close to the mobile or router ,it will got the interference and cause noise ,if connect the deivce 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)

7. USB sound card can’t be identified,After connecting the indicator not glow ,the problem caused by USB Poor contact or external power not enough,pls exclude the USB cable problem or power supply voltage is 5V

8. The device can’t be connected to the PC front USB port ,it easy cause the papapa noise
