wireless microphone

　　1. Avoid using the microphone in humid environment. If the environment can not be changed, wipe the microphone with a soft cloth after use to prevent the internal circuit wires from short-circuiting. 　　2. Use the bracket when using the microphone in summer or indoor temperature is very high, to prevent the sweat from corrosion caused by holding the microphone for a long time, which will affect the microphone. 　　3. Some people used to stick to the microphone on the mouth, saliva or Kazakhstan gas can affect performance, you can use the spray-proof net / spray cover, spray is not only to prevent the jet sound Oh. 　　 BY-SM80 Stereo Condenser Microphone 　　The BOYA BY-SM80 is a stereo X/Y condenser microphone that delivers broadcast quality stereo sound to your DSLR camera, video camera, or audio recorder. This microphone provides greater control of your audio than the internal mics on DSLR camera, video cameras, or digital recorders. Condenser microphone Routine main...

　　According to the internal structure of the microphone can be divided into two kinds of dynamic microphone and condenser microphone , the former principle is to use sound waves to promote the diaphragm, and then shock film driven coil, the use of changes in magnetic lines have a weak voltage. This microphone is the most common microphone on the market, the general arena or hand-held microphone is the majority of this, it does not need external power supply can be inserted directly into the speaker system pronunciation, because this microphone is more portable , The frequency response is not bad, so the popularity is high; 　　 Condenser microphone outperforms moving-coil microphones in terms of sensitivity and extended high-frequency (and sometimes low-frequency) response. 　　This is related to the working principle that the condenser microphone needs to convert a sound signal into a current first. In general, condenser microphone  are very thin and easily vibrated by ...

　　 Condenser microphone is no stranger to us, it will inevitably produce some wear and tear during use, but also need maintenance. Then the question came, condenser microphone how to maintain? Here to share some condenser condenser microphone maintenance guide, hoping to help everyone to maintain their own condenser microphone. 　　There are many translations of microphones: microphones, microphones, microphones, or microphones, or microphones. This article is generally referred to as a microphone. 　　A microphone is a transducer that changes information from one form to another. The sound message was originally a change in air pressure, which was converted by the microphone into a change in current. Recording engineers are particularly concerned about the accuracy of conversion, which is commonly referred to as fidelity. 　　There are a variety of mechanical techniques used to make microphones, the result of the elimination is now the most common dynamic microphone and Conde...

　　In today's era of entertainment and cultural life is extremely active, many business units and other groups will have a lot of entertainment, group activities, these activities, I believe always unwilling wireless microphone . However, the performance of wireless microphone is often affected by frequency interference, user error operation and other factors and a variety of failures. 　　 Wireless microphone from the sound into electrical signals, and then become high-frequency radio waves withered launch, and then receive back demodulation, amplification, reduction into sound this entire process, there are many links. A link did not notice, maybe it can work, but its stability, the scope of work will be reduced a little, did not notice another link, it will reduce the use of narrowing the point, so cumulative, multiple links at the same time A loophole, wireless microphone is not disturbed, is "running frequency", even if the distance is not close to normal...

　　The performance of the Wireless microphone is often affected by the interference of the frequency of peripheral equipment, improper operation by users and other factors and a variety of failures, the next, Xiaobian will teach you how to avoid and prevent the most common Wireless microphone problem. 　　There is a different degree of compatibility between frequencies, and if you are well aware of your system's condition, you can use more systems more aggressively, but the point is how to weigh the compatibility of your entire system. 　　Most frequency-compatible software have an important assumption at design time that all receivers are always on or not mute (even if some transmitters are turned off occasionally) so that all receivers do not pick up To the possible noise intermodulation signal. 　　When the transmitter is located very close to the receiving antenna, or high-power transmitter is running, the interference will be more serious. That's why it is far mor...

　　The most commonly used wireless microphone and IEM operate in the UHF band from 450MHz to 698MHz, the 1.9GHz DECT band and the 2.4GHz band, but different regions may have specific restrictions on the parts of these ranges that can be legally used. There are also some VHF or UHF spectral ranges that can be used, such as 902MHz to 928MHz, but the legitimacy to operate these frequencies also varies by region. 　　Each range of operations faces unique challenges. The 450MHz to 698MHz range is generally suitable for high-channel-count systems or systems that require operating ranges over about 30 meters. The challenge is that this range is also typically used for terrestrial mobile wireless communications, public safety and television broadcasting, and their transmit power usually far exceeds wireless microphone and IEM systems. As a result, wireless microphone  and IEM systems must circumvent these existing services, which is a challenge in areas where the available spect...

　　Each wireless transmitting device occupies a frequency bandwidth while it is in operation, as if each car took up a lane, where frequency is like an expressway and bandwidth is like an infinite number of lanes on a highway, The microphone receiver is like a waiting car on this driveway. When the wireless device is working, if your device uses your frequency band. It's like taking up your driveway. So waiting for the car is often not waiting for their own car. 　　This and your use of genuine or imitation goods, manufacturers or small factory W ireless microphone has nothing to do, all the world's microphone manufacturers have no way to completely solve this microphone receiver is the same frequency signal interference problems. Of course, best-of-breed manufacturers use technology to minimize this possibility. Transmitters minimize spurious emissions such as parasitics, intermodulation, harmonics, etc., while receivers use SQ (squelch threshold) or narrow Frequenc...
