Common problem:
Q: All the lines are connected, but there is no sound output?
Answer: 1. Check if the POWER indicator is on. After the power button is pressed, the indicator still does not light. At this time, you can find an equivalent voltage output (must be 5V) in the test to judge the machine failure or power failure. If the POWER indicator is on, check if the corresponding input signal is selected correctly.
2. If the above two points are checked or no sound, check if the VOL knob is in the minimum state, such as clockwise rotation in the minimum state;
3. If both of the above are normal, check if the playback device of the input source is paused, muted, or the volume is at its minimum.
Q: Why is the sound broken?
A: Although this product is a DAC decoder, it can also be used as a pre-stage product. It has amplifying effect. If the volume of the rear-end device is adjusted to the maximum and the pre-stage is also adjusted to the maximum, it is easy to be distorted. You only need to turn down the volume of the front or back level.
Q: Why does the speaker have a large current sound?
A: If you are not using the original standard power supply, please replace the power supply before testing. A lot of power supply in the market has a large interference coefficient, which will cause a large current sound.
Q: Why do I not play the sound source after I plug in the input cable, and the speaker will have a loud beep?
Answer: When the unshielded signal line is used, the interference signal will enter the amplifier for amplification. If you hate this sound, you are advised to replace the shielded signal line or unplug the signal line.
Q: Can the headphone output connector be connected to a microphone?
A: No, the headphone jack is a signal output interface, not an input interface.
Q: Why is the volume of the machine unchanged, and the sound source is different when accessing different audio sources (such as connecting the CD first and then changing to the mobile phone)?
A: The amplitude of the output signal of different playback devices is different. For example, the mobile phone is usually 0.35MV, and the CD is 1V. The natural sound size is different.
Q: Why is there no sound after the PC-USB is connected to the PC?
A: First press the PC-USB operation to confirm whether the digital playback output is selected. If there is still no sound after selecting it, you can restart the computer and repeat the operation.
Q: Why are lines plugged in, but there is no sound in the RCA analog output?
A: At this time, you should check whether the headphone output is plugged into the earphone, or plug in the earphone adapter. If you plug it in, you need to unplug the earphone or adapter to simulate the RCA output.
