　　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...

　　In the past, the object of the microphone was only a singer. This part of the crowd who is in charge of the microphone will pay attention. Nowadays, many microphones are also used by those who work in the anchor industry. Therefore, many brand microphones are also more common people. 　　Microphones look similar, but in practice, different types of microphones, in different environments, the effect is very different, in general, the microphone can be divided into seven categories. 　　First, dynamic microphone 　　In the microphone, the so-called "moving coil" refers to the wire coil is closely connected with the diaphragm, according to changes in sound pressure, continuous movement in the magnetic field generated in proportion to the amplitude of the sound wave current, so that the acoustic signal into electric signal. 　　Since dynamic microphone  can generate electric current by coil cutting magnetic field, dynamic microphones do not need to be powered, which is th...

　　Microphone in the entire sound reinforcement system on the role of sound is very crucial! 　　However, most people focus on what kind of microphone they choose and how they rely on the tuner's adjustment. 　　Even if the use of high-quality microphones, if you use the wrong method, tuition fees half a day Jin tune, the final may not be able to make themselves satisfied, the effect is also not much better where to go. 　　To make the best use of a hand-held microphone , you first need to understand the pickup characteristics of the microphone, which can directly affect the final result. 　　This feature is the most direct, near large and small. Close to the sound, the location of the front. Far from the sound is small, the location behind. In addition, hand-held microphone are generally heart-type or super-heart-type point, with speaking effect. From the near, the bass aggravate the sound full; farther away, the sound of the bass weakened. 　　What is the "heart-type...

　　 Cardioid Microphone pickup type is directional pickup type, which can be very good isolation of unnecessary sound. While you may see some LAV lavalier microphones that are high Cardioid Microphone pickup types, most of them are typically type pickups for video gun microphones. While each brand is different, the difference between Hypercardioid and Supercardioid is not obvious, but usually the difference between the two is that the higher the heart-shaped microphone picks up more sound behind the microphone and the longer the Cardioid Microphone is Short, also called a mini-gun, is usually used for pick-up of musical instruments. 　　High The Cardioid Microphone mode is a more directional type based on the Cardioid Microphone , with the main difference being the reduction of more side sounds, but also the picking up of the sound behind, which is sometimes referred to as Mini-shotgun microphones, but not all shotgun microphones are high-profile mics. 　　 BY-MM1 Cardioid Mi...

　　 Shotgun microphone choice.
