How to make a wireless microphone at home

　　In theatrical performances, large gatherings or TV programs, I often find that many users feel sorry for the incorrect posture and improper use of the wireless microphone. Because of the mistakes in using it, not only can an expensive microphone not play the original Of the superior features, and buried the original sound quality, the result than using a cheap microphone show the sound even worse.

　　The performance of Wireless microphone is often affected by frequency interference, user error operation and other factors and a variety of failures. How To Avoid And Prevent The Most Common Wireless Microphone Problems:
　　When using wireless microphone, there is always interference between the system itself. Although each system has frequencies or intervals of several megahertz, Intermodulation Distortion (IMD) can still cause interference between microphones. If there is not enough space between the intermodulation signal and the device's operating frequency, it is difficult for the receiver to pick up the signal from the transmitter. Typical phenomena are crosstalk between systems, frequent signal loss or excessive noise and distortion.

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.


　　As a result, the software needs to be designed with enough room for intermodulation signals and wireless microphone. If you assume that the sound system operator is to play a more active role in the activity, then the system needs a wider range of compatibility.
　　Wireless microphone are also subject to interference from other sources on the same spectrum. The most common is usually television stations, FCC rules require wireless microphone users in the same geographical area to avoid the frequency of use of radio and television stations.

　　Workaround: Avoid interference in the 40-50 miles of television channels indoors. When working outdoors, maintain a 50-60 mile radius for normal use.

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...
