How to prevent and avoid the interference of external signals on the wireless microphone Before purchasing a wireless microphone, you should find out the transmitting frequency of the local TV station, and you should stagger it when purchasing. If it is a newly built site, if conditions permit, add high-density wire mesh or iron sheet to the top and surrounding of the building to shield and isolate the interference of external wireless signals.
How to use antennas correctly to ensure signal stability When using multiple sets of wireless microphone systems of the same series, it is best to use an antenna splitter if possible to minimize the mutual interference between the antennas on the original receiver; or to receive wireless microphones Keep the appropriate horizontal distance between the receivers, so that the receivers have better receiving conditions, avoid mutual interference between frequencies, and obtain better wireless signals.
How to identify the wireless microphone in use When using two or more handheld wireless microphones of the same model at the same time, in order to prevent misoperation, the bottom of each wireless microphone (the place that is not easy to block when holding the microphone) should be marked with a different color , At the same time, the channel corresponding to the microphone on the mixer should also be marked or marked with the same color as the microphone. In this way, even if the wrong wireless microphone is taken, the operator can correct it in time. In addition, you can also use the color microphone dust cover as a mark, which not only improves the sound quality, but also serves as a microphone mark, achieving two goals. In order to prevent the wrong use of the lavalier wireless microphone, you can first set the number or color of each microphone transmitter. Before the performance, the person and the machine should be ordered. When the exchange is used, a dedicated person should arrange it.
How to prevent the silent phenomenon that may appear in the performance? During the performance, the singers always use the handheld wireless microphone alternately. Some actors will unconsciously turn off the power of the wireless transmitter or turn on the microphone mute switch to make the microphone in a mute state. In this way, when an actor uses the wireless microphone, there will be an embarrassing scene of no sound from the wireless microphone, which will catch the operator by surprise. Under normal circumstances, when the power of the wireless microphone transmitter is turned off, the transmitter working indicator light on the wireless microphone receiver will go out. If the operator can frequently check the indicator light of the wireless receiver when switching microphones, the problem will be discovered in time. However, if the mute switch of the wireless microphone is turned on, it is only up to the operator to monitor with headphones when the program is alternated. In order to prevent the wireless microphone from being silent, usually the mute switch should be fixed with tape.
The receiver and transmitter can only be successfully matched when they are in the same channel. The 48 channels can be switched in normal operation, and the anti-interference ability is strong. 40 sets can be used at the same place at the same location, the signal is stable, and the penetration is strong;
