With the popularization and extensive use of wireless microphones, how can they play their superior role better, the following issues should be paid attention to in the operation and use:

In order to ensure that the system does not suffer from signal distortion and frequency interference during normal use, it is necessary to use a battery that is sufficient. When purchasing, if you have a sufficient budget, it is best to use an alkaline 9V battery.

Before purchasing a Non-frequency-converting wireless microphone, you should first understand the transmission frequency of the local TV station. When purchasing, you should stagger the transmission frequency of the TV station to avoid interference. When purchasing multiple wireless microphone systems, you should also pay attention to the frequency of each system to avoid mutual interference when the frequencies overlap.

When using more than two handheld wireless microphones of the same model at the same time, each wireless microphone should be marked with a different color to prevent misoperation. Moreover, the mark should generally be placed at the bottom of the handheld wireless microphone so that it is not easily blocked when the microphone is held. At the same time, the same color as the microphone should be marked or marked on the channel corresponding to the microphone on the mixer. In this way, even if the actor mistakenly takes the wireless microphone, the operator can correct it in time when the presenter introduces the actor or plays the song. In addition, you can also use the color microphone dust cover to mark, which not only eliminates the "gasp" sound and the "puff" sound but also can be used as a microphone mark, which is really good for both. Especially when antiphonal or Ensemble singing, it is more important to adjust the volume and tone of each microphone in time according to the color code.

Non-frequency-converting diversity wireless microphone system is subject to external interference (refers to when the transmitter power is off, the RF radio, AF audio or diversity signal still show on the receiver display, which indicates that the receiver is in the interference of external radio waves) The SQUEICH silencer can be tuned to improve reception and reduce interference. The specific method is to adjust the antenna position, the transmitter is still off, the receiver volume output gain is turned off, and finally the SQUEICH static device is adjusted clockwise until all the interference signals disappear (the receiver except the power display) There is no signal display outside), then turn clockwise a little, be sure to use a non-inductive screwdriver when debugging.

When using multiple sets of wireless microphone systems, if the same series of products, if possible, the use of antennas distributor can minimize the mutual interference between the antennas. If there is no antenna splitter, the antenna of the wireless microphone receiver should be adjusted to the optimal position, and then the receivers should be arranged in a row, and each wireless microphone receiver should maintain an appropriate distance (the antennas on each receiver cannot collision), so that each receiver has better receiving conditions to improve the directivity of the wireless receiver, avoid mutual interference between frequencies, to obtain better wireless signals. In addition, the best occasions for large-scale occasions install an extended antenna or an active amplifying antenna to improve reception.
