Weak current College】 【how to use wireless microphone.
<br> <br> As the popularity of wireless microphones and widely used, and how to better play the role of their superior, in operational use of the following issues: <br> <br> 1, optional wireless transmitter for battery: guarantee .system normal use is not to appear signal distortion and frequency interference, must use can battery is sufficient, in the choose when the conditional preferably alkaline 9V battery, for example, the United States "Duracell". If you choose non-alkaline batteries should be .around 1.2-1.6A, 0.8A following cannot be used. In addition, each time before the performance, it is best to measure once, do to have a pretty good idea. <br> <br> How can 2> as possible transmitter .battery energy is abundant in various brands and models of wireless microphone systems, most of the receiver does not have the transmitter battery power display. In spite of a wireless transmitter battery voltage display, but users in the use of General rarely pay attention to this issue .. The normal use of the wireless microphone, a low battery signal distortion caused by audio or frequency interference is almost unheard of. To prevent this phenomenon, the operator can be used in wireless microphone normal use, in a timely manner using a mixer PFL preview .feature and use the headphones wireless microphone signal, if slightly reduces the clarity of the sound or noise slightly increases, it should immediately replace the battery, so as to avoid as far as possible due to insufficient battery power to the operator brings the psychological pressure. .<br> <br> 3 How to show half-way "to replace the battery in the performance of the replacement battery should be easy, fast and simple. The best way is to open the mixer channel's" mute sound "switch to enable wireless .microphone is mute sound State, in the absence of this feature of the mixer can be wireless microphone receiver output volume dies, and then switch off the transmitter power, replace the battery after open the transmitter power and receiver output volume restoration to the original gain, .such as the receiver does not have output volume switch, you can close the sound mixer input gain or use the Line / MIC selector switch to replace the battery after power-on and then a mixer input gain or selector reset. <br> Why not .add a wireless microphone channel faders dies and then replace the battery? here is that if you use close channel faders approach is more cumbersome to replace the battery, in singing microphone plus a general effect processes sound, if using a microphone, a wireless microphone in .need of replacement battery, if you close the channel faders, you should also be appropriate to close for reverb, delay of auxiliary channel potentiometer, if you forget to close the auxiliary channel potentiometer, replace the battery when the shape wireless microphone transmitter power impact sound .from the auxiliary channel after effects output to mixing, direct impact acoustics; Furthermore, if a replacement battery leakage on secondary potentiometer will also appear without the influence of sound effects and sound effects. Here reminds everyone attention is that after each show must cultivate the habit .of removing transmitter power supply (in particular the use of non-alkaline batteries), or sometimes because there is no battery, but forgot to close the shape, the transmitter power from the battery runs out of energy, resulting in battery leakage damage transmitter system .of accident, resulting in unnecessary loss. <br> <br> 4> how to prevent and avoid outside interference for wireless microphone in and purchase non-frequency unlimited microphone before figuring out the local TV station's transmitting frequency, when selects and purchases should .be staggered television transmitting frequency from interference, and purchase multiple wireless microphone system you should be aware of when, how often the system cannot be duplicated in order to avoid overlapping frequency of mutual interference. Where is the new place, conditional upon the top of the .building construction and surrounded by barbed wire or metal to high density for masking, cut off from outside world wireless signal interference. <br> <br> 5 How to eliminate wireless microphone> from outside interference by non-frequency diversity wireless microphone system at .the external interference (transmitter power is off, the receiver monitor still have RF, AF audio or DIVERSITY diversity to A, B in either or both of the LED display monitor signal, the receiver is in the outside world radio interference), TuneUp SQUEICH static .impatient to improve reception, reduce interference. It is, good antenna position transmitter is still off the receiver volume output gain dies, the last tuned SQUEICH clockwise, static bath until all interference signal disappear (display receiver, except the power at this time, there .is no signal), and then clockwise slightly, be sure to use when debugging without induction screwdriver. <br> <br> 6 How to correctly use> antenna signal stability ensured when using multiple wireless microphone systems, such as are of the same .series, conditional preferably use the antenna splitter and minimize the interference between the antenna, in the absence of the antenna splitter, it should first be wireless microphone receiver antenna tuned to the best location, and then had a parallel Word, each wireless microphone receiver to .maintain appropriate distances between (each receiver on the antenna cannot touch), between the receiver has a good reception conditions, to improve the wireless receiver frequency directivity, avoid interference between to get a good wireless signal. Furthermore, the best performance of large applications install .extended antenna or active amplified antenna to improve reception. <br> <br> 1> how to correctly identify is in use during the performance of wireless microphone while using 2 or more same model handheld wireless microphone, to prevent mistaken operation should give each .wireless microphone is not the same color mark or mark. Thus, even if the actor wrong get wireless microphone, the operator may also introduce the presenters and performers or play chip (play) songs when timely corrections before the hash. In addition, you can .use color handset dust cover marking, this not only eliminates the "breathing" and "poof" sound, but also can do phone tag, killed two birds with one stone. Especially when singing the Duet or can stop when, in a timely manner to .adjust the volume level of each speaker and the timbre becomes more important. <br> <br> For collar-clip to prevent wrong wireless microphone, you can first on each microphone transmitter number or color settings to set before the performance, setting machine, .If there are several programs need to alternate, just in case, after each time alternating for by hand, machine registration, and registration to inform operators so as to avoid the mistake. <br> <br> 2> how to prevent the performance .the silent might occur in the performance of singing actors always alternating the use of handheld wireless microphone, actor after use, you may unintentionally disable the wireless transmitter power or open microphone mute sound switch so that the microphone is mute sound State (this class wireless microphone .transmitter power switch and microphone mute sound switch is installed in the fingers easy touch location such as SHURE-T series handheld wireless transmitters, etc), then an actor using the wireless microphone appears wireless microphone no sound of embarrassment, not only affects the actor's performance ., also affect the audience watching the mood, perhaps also will make the operational staff by surprise, as this must pay great attention. In fact, when the wireless microphone transmitter power is turned off, wireless microphone receiver DIVERSITY on the transmitter monitor LED will go .off, if the operations staff in the use of the wireless microphone, you can turn the program frequently viewed wireless receivers work status is to be able to find this phenomenon. However, if the wireless microphone mute sound switch is switched on, the vast majority .of wireless microphone receiver cannot be displayed. Unless the operational staff in programs when you are using headphones, turn to listen (generally not very realistic). <br> <br> In order to prevent a wireless microphone sound occurs, the operator should be .performed prior to such switches are exposed wireless microphone transmitter power switch and microphone mute sound switch, taped for fixed, such as a microphone switch protection set, then each should be used (SHURE LX series handheld wireless microphone is equipped with a microphone switch sheathed) ., so the wireless transmitter and receiver is always working to ensure that performing normally. <br> <br> 3> how to operate the good lumbar hanging wireless microphone lumbar hanging wireless microphone generally using miniature electret capacitor microphone, the microphone sensitivity is high .and, in the use of all links to easily produce acoustic feedback, especially on the stage and return to listening to the speaker used the Forum to do this type of microphone to Opera and essays show, such as the stage is the floor, the floor .here and a cavity, to prevent the low frequency resonance, it should be on the road a mixer Channel Bass gain as appropriate, will return to the attenuation of the sound system of signal output gain also make the necessary attenuation, General decay rate in case .of 6DB above sketch show on passion can also return to the auditory system for signal output to prevent acoustic feedback. <br> <br> 4 how to correctly use radio> musical instrument system radio musical instrument system, mainly used in electric guitar, .electric organ, double Division, as well as PC drum synthesizers and other audio sources. And wireless microphone systems mainly pickup in different ways. Microphone pickup is low impedance output and electro-acoustic musical instrument pickup is a high-impedance output (microphone to 0DB .output, electro-acoustic musical instrument output for-20DB), the use of electro-acoustic musical instrument should be a wireless transmitter on LINE / MIC (line / MIC) switch, set in LINE (line) of the location; at the same .time, the appropriate adjustment of the transmitter's gain, to adjust and control the excessive level of distortion. Wireless microphone receiver should be LINE / MIC (line / MIC) switch, set in LINE (line) of the location; then, will the wireless .microphone receiver LINE (line) output access mixer on the LINE (line) input connector. This not only makes the electro-acoustic instruments and devices that are truly impedance matching, level combined with properly, but also to make the best electro-acoustic musical .instrument performance. If you set LINE / MIC (line / MIC) switch set in the MIC / Mic position, access the MIC / microphone mixer faucets will cause distortion. Serious damage to the device will be. This is due to the electro-acoustic .musical instrument high-impedance output access microphone low impedance input impedance mismatch, after level mismatch, so operation is carefully. <br> <br> 5> how to make wireless handset to play the best results for wireless microphone for best results, you .must handle the transmitter output level gain, receiver output gain and mixer input gain among relationship, if handled improperly, you may receive the voice repressed, without penetrating or distorted sound, even radical. <br> <br> The correct action is to connect .wireless microphone receiver and sound system and the audio system-level (0DB / + 4DB) set, power release to maximum output, while the mixer main output volume set at 0DB, open wireless microphone transmitter power and wireless microphone transmitter audio output gain set at .70% -75%, and mixer on wireless microphone input channel channel potentiometer at 0DB; last fine-tune the sound mixer input gain, if necessary, can also be slightly adjusted transmitter audio output gain until the microphone effect is satisfied. <br> .<br> <br> <br> <br>.
