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.

BT setting:

1. Pls Put the selector switch at the “BT ”position,then the CNCT indicator will flash quickly

Using Mobilephone as example :enter Mobile “setting “-BT ,Click :search device ,then you will search out “Douk Audio” click “Douk Audio ”match the device with douk audio ,

After matching well the CNCT indicator will flash slowly

We recommend using the mobile with ATPX function ,the sound quality it best


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 again 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. USB sound card can’t be identified,If 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

7. The device can’t be connected to the PC front USB port ,it easy cause the papapa noise 
 
8. Under BT mode the Effective linear distance is near 10 meter ,the best distance is within 5 meter (without the wall or obstacles )
 
9.If you find the BT can’t match,pls power off the device 1 minute later then power it on and match it again
