Q: All my wires are connected. Why is there no sound?
A: 1. Check whether the machine is started, whether the indicator light is on, and whether it is
switched to the corresponding input channel.
2. Check whether the rear stage is connected correctly and whether the volume is at the
minimum.
3. If the above is normal, check whether the input playback device is muted, paused, or the
volume is at the minimum.
Q: Why is the sound distorted?
A: The input level may be too large. If the volume of the input device is turned on to the
maximum and the volume of the machine is turned on to the maximum, it is easy to distort.
Just turn down the volume of the sound source input device or machine.
Q: Can I use the 3.5 microphone to connect to the machine to sing?
A: Yes, type-C data input is connected to a computer or mobile phone, and 3.5 microphone
input supports recording and Call function.
Q: When I connect my mobile phone, can I answer the phone directly when there is a call?
A: Yes, the prerequisites must be 3.5mm, 4-segment plug and earphone with microphone.
Q: Why do I connect this device to my mobile phone with a mobile phone charging cable,
but the mobile phone cannot find the device and cannot realize the OTG function?
A: the ordinary mobile phone charging cable only has the normal data transmission and
charging function, and does not have the full function of type-c. if you need to use the
OTG function, please use the full function type-C cable.
Q: When the 3.5 microphone, microphone and listening 2-in-1 headset are plugged in at
the same time,Why does the microphone of the two in one headset have no sound?
A: 3.5 microphone is the first choice (if you need to use a two in one headset, not plug in 3.5
microphone or unplug 3.5 microphone plug).
Q: Why is the 96KHz sampling rate selected for both the speaker and microphone, but the
microphone has no sound?
A: The USB sound card of this device is drive free mode because the bandwidth limitation does
not support bidirectional 96KHz mode. It is recommended to reduce the sampling rate of
the microphone.
