Q&A
Q: Why is it noise?
A:
1.One situation, the USB interface on the device (computer, TV, etc.) may be used to supply power to the mixer, but this type of USB interface power supply contains many interference.It is amplified and output when you enter the mixer.
2. Also, when multiple devices use different power sources, the ground signal is uneven (fluctuation) and when these devices are connected through the mixer, the fluctuation may be amplified and outputed.
Q: How to remove noise?
A:
1: For noise generated by the power supply, we recommend you try to change the power and use a separate power adapter to power the mixer.
2: For noise caused by ground noise, please change the power of the output device. Usually, using ground noise isolator, the problem is solved.
Q: Does this product support microphone?
A: Since this product does not have microphone bias or amplification function, the microphone cannot be connected directly to the input. The microphone must be connected via an external mic preamp.
