Henan where to sell wireless microphone store

For bodypack wireless microphone in order to prevent wrong to take, can be carried out number or color set for each microphone transmitter, carried out before the show will be people, machines, if there are several programs for an alternate use, just in case, you can After each person alternately by hand, machine registration, the operator will announce the registration, in order to avoid operational errors. Song Sen 132 * 1308 * 8890 69 * 139 * 139 www.69139139.com qq: 269 * 291 * 1508 Hanam technology market in Milan sun, Building 5, Unit 2, 208 VIII show how to prevent silent phenomenon that may appear in the show singers have always used interchangeably handheld wireless microphone, some actors use, you may unconsciously turn off the wireless transmitter power, or open microphone mute switch, so the microphone is in mute state (such wireless microphone transmitter power switch and microphone mute switch is mounted on the fingers easily touched position, there will be no sound wireless microphone embarrassment at this moment an actor using the wireless microphone, then not only affects the actors emotions, but also affect the viewing audience interest and perhaps allow the operator surprise, this must pay close attention. In fact, when the wireless microphone transmitter is turned off, DIVERSITY transmitters operating display LED on the wireless microphone receiver goes out, if the operator to use When the wireless microphone, when the program can always check the working conditions of alternating radio receiver is able to discover this phenomenon. However, if the wireless microphone mute switch is turned on, the vast majority of wireless microphone receiver can not be displayed. unless the operator when the program alternates are listening with headphones (usually unrealistic) Song Sen 132 * 1308 * 8890 69 * 139 * 139 www.69139139.com qq:. 269 * 291 * 1508 Hanam sun technology market in Milan 5 wireless microphone transmitter power switch and microphone mute switch Unit 2, Building 208 wireless microphone in order to prevent the occurrence of the phenomenon without sound, the operator shall, prior to the performance of this type of switch is relatively exposed fixed with tape, if the microphone switch protection set, then each should be used to make a wireless transmitter and a microphone is always active, in order to ensure normal performance. Nine, how to operate a good bodypack wireless microphone bodypack wireless microphone commonly used miniature electret condenser microphone Such high-sensitivity microphone is omnidirectional, it is easy to generate when using the acoustic feedback, use back to listen to the speaker of the occasion in particular on the stage, for this type of microphone is used when drama and comedy performances, such as the stage is the floor, floor below is a cavity, then, to prevent low-frequency resonance, the gain of the bass should mixer channels make appropriate attenuation, while the back to listen to the signal output gain of the system is also necessary attenuation, attenuation range of general 6DB above, such as the case of passion sketch show resectable return signal output to listen to the system in order to avoid acoustic feedback Song Sen 132 * 1308 * 8890 69 * 139 * 139 www.69139139.com qq:. 269 * 291 * 1508 Henan City technology market in Milan sun, Building 5, Unit 2, 208 ten, how to properly use the radio system radio acoustic instruments musical instrument system, is mainly applied to the electric guitar, electric fold Division, organ, synthesizer and drum computer and other sources. And wireless microphone systems are different pickup different major way. Microphone pickup is low impedance output and electro-acoustic instrument pickup, compared with a high-impedance output (microphone is 0DB output, electro-acoustic musical instruments - 20DB output), so should be used with acoustic instruments in the LINE / MIC on the wireless transmitter (line / microphone) switch is set to LINE (line) position; a corresponding gain to suitably adjust the transmitter to adjust and control the excesses of distortion level. Wireless microphone receiver should also be LINE / MIC (line / microphone) switch is set to LINE (line) position. Thus, not only between acoustic instruments and truly impedance matching device, with the proper level, and also enable electronic musical instruments to play the best performance. If the LINE / MIC (line / microphone) switch is set to MIC / microphone position, access to the mixer / MIC microphone jack can cause distortion after. But also serious damage to the device. XI, how to make a wireless microphone to play the best results to enable wireless microphone to play the best results, it must deal with the transmitter output level gain, relationship receiver output gain and mixer input gain among the three, as improper handling may occur if the sound depressing, no penetration or sound distortion, even radical.
