wireless microphone

　　The Wireless Microphone gives us great convenience, freedom to move, and ease of use. But they are not without drawbacks, the following will discuss how to properly use the Wireless Microphone , so as to maximize avoid weaknesses. 　　About frequency: A complete wireless system consists of a transmitter and a receiver, which must be set to the same frequency. 　　Because of this wireless frequency sharing, others in the same area may be using the same frequency as you. 　　Tips for new users 　　1, tell the host, recording engineer how to control the microphone switch. Affix the switch on the transmitter so they will not touch it. 　　2. Consider in advance which moderator's head is most likely to turn when facing someone on stage or in the auditorium. If you can not place the microphone in the middle of your tie or shirt, do not be on the side where he / she is most likely to be heading. 　　 BOYA BY-WM5 wireless microphone is for use with DSLR cameras, camcorders. The 2.4...

The operator should carefully check the wireless microphone before performing or using it, connect the system correctly, and set up the antenna reasonably to ensure that the microphone is in normal working condition, so as to avoid the silence of the wireless microphone during the performance or use. The main points to note are as follows: 1, check the battery box is in good contact, the battery is energized. 2, the boot should first open the receiver, check the RF header to determine this channel without RF interference, and then open the emitter. 3, check the microphone mute switch to ensure that the wireless transmitter and microphone is always in working condition. 4, do not pile up the receiver, so as not to interfere with each other between receivers. 5, after the end of the power to take out, because individual microphones are tactile switch, are in standby mode, or live work, do not remove the battery power will run out. Use should pay attention to the problem (1) Dur...

　　 Wireless microphone , also called wireless microphone, consists of transmitting and receiving. Among them, the launch part of the battery-powered microphone to convert sound to audio signals, after the internal circuit processing, audio information can be radio waves emitted to the surrounding space. 　　The receiving part is usually powered by the power supply, the receiving antenna receives the radio wave transmitted by the transmitting part first, then processes the internal circuit to extract the audio signal and then transmits it to the sound amplification system through the output signal line to complete the wireless transmission. 　　Understand the working principle of wireless microphone , here to talk about the wireless microphone when you need to pay attention to what issues. 　　First, pay attention to impedance matching 　　The output impedance of the wireless microphone , which is the same as the input impedance of the amplifier, is the best match. If the mismatch...

　　Nine high-quality wireless microphone prerequisites 　　Advances in radio communication technology have promoted the improvement of the quality and functionality of wireless microphone products. With the increasing number of manufacturers in the industry and the declining prices, consumers have become more and more interested in this product. I provide the current product innovation design and technical essentials, to help judge, buy value products. 　　(1) Design Appearance Ergonomic and aesthetic hand-held wireless microphone tube body must have a palm-sized handle and the size of the beautiful shape, the general traditional tube were bamboo or conical, not only without beauty, nor Too fit palm grip, easy to sweat who hold easier to slide. The most suitable shape for the hand is the middle double than the two ends of the curve shape. 　　(2) The use of advanced antenna hidden antenna design of the early wireless microphone rear external antenna, and advanced wireless micr...

　　We first understand the strengths of wireless microphone : 　　 Wireless microphone eliminates the need for transmission cables, making pickups simple and convenient. Taobao used to move the sound source, which ensures that the sound source and microphone spacing consistency. In the same period of film and television recording, you can rule out the microphone or its shadow on the screen image interference, improve visual effects. 　　Although there are so many advantages of wireless microphone , but it also has some disadvantages, because more transmitting equipment and receiving equipment, an increase of the cost of the microphone. The wireless microphone is a radio frequency transmission, anti-interference ability is poor, but also interfere with other electronic devices. Another reduction by modulation, transmission, reception, demodulation and other more complex process. Sound quality will also be affected. 　　 BY-WM8 Dual Channel UHF Wireless Microphone System 　　The ...

　　 Wireless microphone , also known as wireless microphone , consists of two parts, transmitter and receiver, usually called wireless microphone system. The transmitter is battery powered and the microphone transforms the sound into an audio electrical signal that, after being processed by internal circuitry, emits radio waves containing audio information into the surrounding space. The receiver is generally powered by the mains. The receiving antenna receives the radio waves from the transmitter. After being processed by the internal circuit, the receiver extracts the audio signal and sends it to the sound reinforcement system through the output signal line to complete the wireless transmission of the audio signal. A receiver usually can contain 1 set, 2 sets or 4 sets of receiving circuits, respectively, to receive 1, 2 or 4 wireless microphone signal, of which two are the most common. 　　 BY-WHM8 UHF Wireless Handheld Transmitter 　　The BOYA BY-WHM8 is a Wireless hand...
