How to Decide Between a Wired and Wireless Microphone ?

　　A perfect wireless microphone, will bring great convenience to people's use, at the same time to the sound engineer on-site pickup provided the space for artistic creation. Therefore, when constituting one sound system, a wireless microphone is provided more or less.
　　There are many kinds of wireless microphone called: wireless microphone, wireless microphone, wireless handheld, wireless headset, wireless chest, wireless microphone system, generally will not cause any misunderstanding.
　　Relatively speaking, Wireless microphone are more expensive than wired microphones, which are more technically complicated and more delicate in use. Therefore, this article is about how to choose and use wireless microphone for an introduction.
　　Wireless microphone from the initial simple one wireless FM transmitter and wireless FM receiver to the current use of a dedicated PLL (Frequency Locked Loop) technology, has gone through about three stages.

　　BY-WHM8 UHF Wireless Handheld Transmitter
　　The BOYA BY-WHM8 is a Wireless handheld transmitter with a dynamic, cardioid capsule, suitable for BOYA BY-WM6 and BY-WM8 wireless receiver. The BOYA BY-WHM8 provides professional, portable wireless operation in the 24MHz band, is easy to operate and affordable. It features an easy to read LCD display, easy one-touch channel search and lightweight plastic housing.
UHF Wireless microphone
1: Simple FM transmitter and receiver
　　At that time, in order to get rid of the fetters of the microphone cable, people came up with the principle of transmitting and receiving similar to FM radio. Through the microphone's transduction principle and audio → modulation → amplification → transmitting process, and then through the FM radio or special receiver ) Receive, playback. Can be imagined, its sound quality, stability, anti-interference ability, etc. can not meet the actual needs.
　　2: Quartz oscillation FM transmitter and receiver

　　Due to the RC or LC oscillation generated by the electronic circuit, the stability of the oscillation frequency is greatly affected by the environment and its frequency can not be very high. Generally, the oscillation frequency is generally lower than two or three hundred megahertz. In such a frequency band, Very susceptible to interference from other signals, this time there has been the use of quartz oscillator transmitting and receiving circuits. As we all know, quartz crystal oscillation frequency is very stable, composed of Wireless microphone transmitter and receiver, work more stable, at the same time, its working frequency can be V (30MHZ-250MHZ), U (200 -1000MHZ), the external interference signal is not serious, to the use of wireless microphone brought better results.

What does a shotgun microphone do

　　There has always been a saying: shotgun microphone is not suitable for use in indoor recording. So I recently started to study this problem, trying to find the exact answer, to do some testing for this. 　　 Shotgun microphone wind, the purpose of using these devices, mainly to enhance the axial pickup capacity, while reducing the side of the interference noise. In other words, let the microphone play its directivity as much as possible, in order to avoid unwanted noise and ambient sounds. 　　This is another mode, we can see the reaction of ordinary shotgun microphone wind. Uneven sides, and the effect of the posterior leaf under the influence of an intervening tube. 　　In an echoed space there will be diffuse, especially early reflections, the color of the signal part. Ideally, the microphone depends on the angle of the transform, if the sound is a correlated signal or just a noise. When both the signal and the noise are reflected on the nearby surface, it is an "unn...

How to connect wireless microphone to pc ?

　　 Wireless microphone 's history is not long, also a decade or two of history, but the development is extremely rapid. Eighties, we seldom see. Products nothing more than Newman, Siya and other international few microphone manufacturers; in the application, only to see large-scale concerts in foreign countries. With the passage of time, brands such as Audio-Technica, Sennheiser and Shure gradually entered the domestic high-end sound system. 　　Understand the Wireless microphone technology, we can according to their own financial resources to buy a suitable wireless microphone. 　　In general use, such as not far from (twenty meters within), used in meeting rooms, function rooms and other occasions, the case of small movements, you can choose quartz oscillating class, single receiver Wireless microphone , Microphone optional moving coil, electret and other types, conditions permit, but also choose PLL type wireless microphone. 　　In the performing arts clubs and theaters...

Top 10 Best steadicam for DSLR camera Video Work

图片
　　 The best steadicam for DSLR cameras cannot simply be measured in terms of its price. There are a number of parameters that you have to consider before making that buying decision. It has to check at least 3 to 4 boxes before it even becomes a potentially great buy. Here are a list of the few best steadicam for DSLR camera systems that we could find. 　　It is capable of supporting a camera system up to 3.9 lb. Additionally, this is one of the rare few handheld stabilizers that come with support for long lenses. The system comes with 3 32-bit MCU’s which run parallel. 　　At the bottom of the stabilizer there is a ¼” – 20 threaded mounting hole. This mounting hole allows you to optional use the stabilizer with monopods and other support systems. Mini Action Stabilizer SK-W08        　 Mini Action Camera Stabilizer SK-W08 　　 Sevenoak Mini Action camera Stabilizer SK-W08 is a compact, ultra-light Camera stabilizer that uses counterweights and gimbal to h...
