3、w can you know as soon as possible transmitter battery power is eno ugh in a variety of bra nds and models of wireless microphone systems, most of the receiver does not have the transmitter battery power display function although there are low battery pressure on some wireless transmitters, users ar

4、e less likely to notice the problem in use in the normal use of the wireless microphone, the occurrence of a battery shortage can cause an audio signal distortion or frequency interference to prevent this kind of phenomenon, the operator can be in the normal use of wireless microphones, timely use m

5、ixer pfl (persistent functional language) function of pre-listening, use headphones wireless microphone signal, if the voice clarity is slightly reduce or noise increases slightly, you should replace the battery right now, as much as possible so as to avoidbecause of a shortage of battery power for

6、the operator to bring the psychological pressurethree, how to change the battery during the performance to replace the battery during the performance should be convenient, quick, simple is the best way to open the mixer channel retuned switch, retuned to make wireless microphone, such as the mixer o

7、f the without this feature can be wireless microphone receiver output volume of close to death, and then turn off the transmitter power, replace the battery after open the power of the transmitter, then the gain of the receiver output volume restoration to the original, such as receiver without outp

8、ut volume switch, can shut down mixer or using line/mic input gain selector switch, after waiting for replacement battery boot to reset the mixer input gain or selectorwhy not switch off the wireless microphone passageway and replace the battery? there needs to be clear, if the method of using close

9、d channel pusher replacement battery is cumbersome, general microphone is effect is added processing in singing sound, if a receiver, when using a wireless microphone need to replace the battery, if close the channel pusher at this moment, at the same time should also be closed for corresponding rev

10、erberation, the auxiliary channel potentiometer, if forget to close the auxiliary channel potentiometer, replacing battery shape wireless microphone sound transmitter power impact from the auxiliary channel via effect instrument output to mixing, directly affect the acoustics; in addition, if the ba

11、ttery is replaced, the auxiliary potentiometer will also appear without the sound effect and affect the sound effect special remind everybody here cause attaches great importance to is that every time after the show be sure to get into the habit of take out the transmitter power (especially the use

12、of alkaline batteries), or sometimes because there is no take out the battery, and forgot to close the transmitter power shape, caused by the battery run out of energy and transmitter system causing damage of battery leakage accident, cause needless loss.fourth, how to prevent and avoid the interfer

13、ence of outside of wireless microphone should be taken before the choose and buy the infinite frequency receiver to understand local television transmission frequency, when the choose and buy should be staggered television transmitting frequency from interference, multiple wireless microphone system

14、 should also pay attention to the choose and buy, the frequency of each system can，t repeat, in order to avoid the interference of frequency overlapfive, how to eliminate the wireless microphone by the interference of frequency diversity in wireless microphone system is outside interference (refers

15、to the transmitter power is closed, there is still a rf radio frequency on receiver monitors, audio af or m diversity to a and b in either or both of the led display have the signal display, indicates the receiver radio interference) is in the outside world, can be set-up by squeich mania to improve

16、 receiving and reduce interference the idea is to tune the antenna and the transmitter is still off.volume output gain close to death, the final adjustment clockwise squeich static mania, until all the jamming signal disappears (receiver at this time in addition to the power supply shows no signs),

17、clockwise turn a little again, must use when debugging without induction with a screwdriversix, how to properly use the antenna to ensure stable signals when using multiple sets of wireless microphone system, so the same series products, conditional word can use the best antenna distributor, as far

18、as possible, reduce the interference among antennas, such as no antenna distributor, should first dispatch of wireless microphone receiver antenna to best position, then parallel a spread eagle, keep a proper distance between each wireless microphone receiver (and not touching the table on the recei

19、ver antenna), make each between receiver has good conditions, to improve the directivity of the wireless receiver, avoid mutual interference between the frequency, in order to obtain better wireless signals in addition, the big occasions performance best installation extension of active antenna or a

20、ntenna to enlarge, to improve the reception.seven, how to correctly identify are using the wireless microphone performance than using 2 same handheld wireless microphone at the same time, in order to prevent wrong operation should be wireless microphone for all of them marked in different colors, an

21、d mark should be affixed to the handheld wireless microphone commonly the bottom, not easy to block, when holding a microphone in tuning stage with the receiver at the same time the corresponding channel should also be labeled with the same color of the phone tag or make the mark in this way, even i

22、f the actor is using the wireless microphone incorrectly, the operator can correct the performance of the actor，s time or in the front of the show in addition, still can use color microphone dust cap marking, such not only can eliminate the "breath" and poof sound, but also can do phone ta

23、g, it is kill two birds with one stone really. in particular, it is more important to adjust the volume and tone of each microphone in a timely manner when singing or resingfor wireless microphone to prevent mistakes and pocket type, one for each receiver transmitter to set number or color, before t

24、he performance of a person, machine, such as several programs to be used interchangeably, in one thousand, but after each alternate registration for man, machine, and inform the operator the registration problem, in order to avoid erroreight, how to prevent the performance of silent phenomenon that

25、may occur in the singing actors always alternate use of handheld wireless microphone, after some actors use, may unconsciously closed wireless transmitter power or turn on the receiver retuned switches, make the microphone in the retuned state (such as wireless microphone transmitter power switch an

26、d retuned microphone switch installed in the position of the finger to touch, so that the moment an actor can appear when use the wireless microphone wireless microphone no sound awkward scene, not only affects the performance of the actors mood at this moment, can also affect the audience watching

27、appetite, maybe still can make operators unprepared, therefore must attach great importance to. in fact, when the wireless microphone transmitter power was shut down, the wireless microphone receiver，m transmitter display led will put out in the work, when use the wireless microphone, if the operato

28、r is able to show alternate frequently to check the working condition of wireless receiver is to be able to find thisphenomenon. however, if the wireless microphone retuned the switch is opened, is the vast majority of wireless microphone receiver cannot be displayed unless the operator when show al

29、ternating with headphones (generally unlikely)in order to prevent the wireless microphone no sound, the operator should be in before the performance of this kind of switch is exposed wireless microphone transmitter power switch and retuned microphone switch, fixed by adhesive, such as have the micro
