Troubleshoot the KTV wireless microphone system Even though the KTV wireless microphone system seems to be selected and installed properly, problems may occur in actual use. Although it is impossible to propose a comprehensive solution for all possible situations here, we will propose some general guidelines.
Although the problems with KTV wireless microphone systems ultimately manifest themselves as sound effects, these sound effects may also be symptoms of audio and/or radio problems. In either case, the purpose of troubleshooting is to find the root cause of the problem first, and then reduce or eliminate the problem.
The following abbreviations will be used below:
AF = audio
RF = radio frequency
RFI = radio frequency interference
TX = transmitter
RCV = receiver
A common symptom in multi-system operation is the explicit activation of two receivers by one transmitter. The reasons can be attributed to the following: the operating frequency is the same or too close, the crystal harmonics, the image frequency of the transmitter is the same as the second receiver, and the intermodulation distortion with unknown sources, etc. If activating the second transmitter makes the two systems work properly, the effect can be ignored. The recommended operating procedure is to turn on the receiver only when the transmitter is active. If you need to support turning on the receiver without using the transmitter, you can readjust the squelch setting. Otherwise, the operating frequency may need to be changed.
