There is noise, disconnection or howling when using the wireless microphone. How to solve it?

These problems are usually caused by three reasons: 1. Incorrect wiring or poor contact; 2. Frequency interference (such as being close to other wireless devices); 3. Improper gain adjustment. You can contact our technical customer service, and we will provide one-on-one remote troubleshooting and solve the problem within 24 hours.
