Compared to wired microphones, wireless microphones are more convenient to use, they are free to move and easy to operate. But if you don't have the right way to use it, you will have various problems.
First, the impact of frequency If two microphones work on the same frequency, it will cause interference, can not be used, and two transmitters can not use one receiver at the same time. The receiver must have one or two external antennas, and there should be an open transmission space between these antennas and the transmitter.
Increasing the squelch parameter at the receiver can effectively avoid interference, but it will reduce the range of use. Computers and other digital devices are common sources of wireless interference. When using a microphone, try to turn off these unnecessary electronic devices. If necessary, make sure that the electronic device is at least 3 feet away from the receiver and antenna.
Second, the wireless microphone operation should be correct when using the wireless microphone, do not put the transmitter in the pocket, because if you unconsciously put your hand into the pocket, you may touch the switch or pull the line, and if there is something else in the pocket, It also has an effect on the transmitter, preferably on the belt or belt of the host.
Although the wireless microphone can move freely, it sometimes moves too much and accidentally approaches the speaker, which is easy to generate feedback. If the user has to go everywhere, then it is necessary to know what to do once the signal is lost, sometimes a step on the side, or even a little offset, may solve the problem.
Third, the wireless microphone battery Before using the wireless microphone, be sure to ensure that the battery is fully charged. If the microphone is low or dead, it can lead to a variety of problems such as no signal, reduced working range, and distortion and interference. If there is a problem with the battery, replace it in time. Do not mix old and new batteries. Also, use a new high quality alkaline battery.
How to prevent and avoid the interference of external signals on the wireless microphone Before purchasing the wireless microphone, you should first clear the transmission frequency of the local TV station. It should be staggered when purchasing. If it is a new construction site, if there are conditions, high-density wire mesh or iron sheet should be added to the top and the surrounding of the building to shield and isolate the interference of external wireless signals.
How to use the antenna correctly to ensure signal stability When using multiple sets of the same series of wireless microphone systems, it is best to use the antenna splitter if possible, to minimize mutual interference between the antennas on the original receiver; or to receive wireless microphones The machine maintains an appropriate horizontal spacing so that each receiver has better reception conditions to avoid mutual interference between frequencies to obtain a better wireless signal.
How to identify the wireless microphone in use while using more than 2 handheld wireless microphones of the same model at the same time, in order to prevent misoperation, mark the bottom of each wireless microphone (where the microphone is not easily blocked) with different colors. 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 wrong wireless microphone is taken, the operator corrects it in time. In addition, you can use the color microphone dust cover to mark, which not only improves the sound quality, but also can be used as a microphone mark. In order to prevent the wrong clip-on wireless microphone, you can set the number or color of each microphone transmitter first. Before the performance, you can make a fixed, fixed, and exchanged use.
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 the next actor uses the wireless microphone, there will be a scene in which the wireless microphone has no sound, which will make the operator unprepared. In general, when the wireless microphone transmitter power is turned off, the transmitter work indicator light on the wireless microphone receiver will go out. If the operator can frequently check the wireless receiver indicator while exchanging the microphone, the problem will be discovered in time. However, if the mute switch of the wireless microphone is turned on, only the operator listens with the headphones while the program is alternated. In order to prevent the wireless microphone from being silent, the mute switch should usually be fixed with a tape.
The receiver and the transmitter can only be successfully matched in the same channel. The normal operation of 48 channels can be switched, and the anti-interference ability is strong. At the same place, 40 sets can be used at the same time, the signal is stable, and the penetrating power is strong;
The transmitter of the wireless microphone is the input interface of the microphone: LINEIN port, which is mainly used for connecting the audio signal output recording of an external device such as an electric guitar synthesizer. Since these devices have large output power, they need to be connected to the LINE IN port;
The receiver is mainly a stereo audio output interface: mainly includes a power switch, a power supply slot, an antenna, an antenna A LED indicator, an antenna B LED indicator, a power LED indicator power LED indicating a blue light, working; a power LED indicating a red light, The battery is too low, in fact, this is similar to the phone, then the channel indicator, battery indicator, headphone port, volume button, setting button, etc.;
When using a wireless microphone, Xiaobian should remind everyone here that the transmitter and receiver are successfully synchronized on the same channel. When the recording is not clear and the signal is unstable, try to adjust to other channels for frequency. Recording, when the device emits a red indicator light, please pay attention to replace the battery to continue working. Please ensure that the electromagnetic is installed with the correct polarity when using it, otherwise it will not work properly.
