Frequently Asked Questions

1: All the cables are connected, but no sound output?

• Check whether the display screen is bright or not. If the display screen is still not bright after starting up, you can find an output of the same voltage (must be 12V) in the test to determine the machine failure or power failure.If the display screen is bright, check whether the corresponding input signal is correctly selected.
• If the indicator light is on, check whether the VOL knob is in the minimum position. If so, turn clockwise to normal Volume
• If both of the above are normal, check the input device if it is paused, mute, or the volume is minimized.

2: Why does the sound is cracking ?

This product is for the DAC decoder, but also can be used as preamp, If post equipment is max volume & preamp too, it’s easy to distortion, you just need to turn down the volume of the equipment, then ok.

3: Why do loudspeakers make a lot of electric noise?
if you are not using the original factory standard power supply, please replace the power supply before testing.Many power supply in the market have large interference coefficient, which will cause a lot of current sound.

4: Why the speaker has drone when I just plug in the input cable but don’t connect the sound sources?
If you use unshielded signal lines, there will be interference signals entering the power amplifier. If you hate the sound, you are advised to use the shielded signal lines or unplug the signal lines.

5: Can the 6.35mm headphone output port connect to the microphone?
no, the headphone interface is the signal output interface, not the input interface.

6: Why does the volume of the machine stay the same, while the sound of different audio sources (such as CDS and mobile phones) is different?
The output range of different types of audio source devices is different, the mobile phone is usually 0.35mV, and the CD is 1V.The signal output amplitude of the sound source will directly influence the volume.

7: Why there is no sound when PC-USB connects to PC?
First press the PC-USB operation to confirm whether the digital playback output has been selected. If still no sound, you can restart the computer and repeat the operation again.

8: Why is it that all my wires are plugged in, but the RCA analog output is silent?
At this point, you should check to see if the headphone output is plugged into the headphone or headphone adapter.If so, you should unplug the headset or headphone converter to simulate RCA output.

9: Why can’t I find the bluetooth pairing name
the machine is designed to be energy efficient and environmental friendly. To use bluetooth, you must switch to bluetooth input mode to search for pairing.

10: Why not support DSD files and the sound is salsa?
playing DSD file does not support PC tuning volume, only the default maximum volume.

11: Does a driver need to be installed on a MAC?
no, the MAC system is driveless and can be used directly.
