Matters needing attention in practical application of wireless microphone

In today's era of extremely rich material products and extremely active cultural life, many enterprises and institutions have many entertainment or group activities. In the media and entertainment circle, there are TV program production, large-scale singing and dancing performances, concerts, major events and other activities. In these activities, I believe that wireless microphones are always indispensable. Wireless microphones have gradually replaced due to their superiority and convenience. Wired microphone.

The wireless microphone is transformed from sound to electrical signal, and then transformed into high-frequency radio waves, and then received back to demodulate, amplify, and restore to sound. The whole process has many and many links, one link did not notice, may It can still work, but its stability and working range will be reduced a little. If it is not noticed in another link, it will be reduced a bit, and the scope of use will be reduced. So accumulated, there are loopholes in multiple links at the same time, and the wireless microphone is not Interference is "running frequency", and it cannot be used normally even at a close distance. On the contrary, every link has noticed that the anti-interference ability of the wireless microphone will be greatly strengthened and the stability will be greatly improved. Even if the use distance is very far, even beyond the use range specified by the manufacturer, it can be used normally.

The following are some issues that should be noted in the selection, operation and use of wireless microphones.

1. Selection of wireless microphone

If the requirements for sound quality are not high, the budget is limited, the distance of use is not more than 30m, the movement range is not large, and the number of microphones is not much. Generally, wireless microphones of quartz oscillation type and single reception can be selected. Polar body and other types.

In small theaters, theaters, multi-functional conference halls, etc., due to the large movement range, complex reception conditions, and high requirements, it is recommended to use PLL frequency synthesis type wireless microphone. The microphone head can be selected from the capacitive or dynamic coil type. For special requirements, other types of microphones can be selected.

In large theaters, stadiums, studios and other places with high requirements, it is recommended to choose a diversity wireless system with PLL frequency synthesis receiving technology. Due to the large number of microphones in these occasions, the complicated receiving environment, and the wide range of use, auxiliary equipment such as antenna amplifiers, distributors, and antennas should also be configured to improve the use effect and obtain better wireless signals.


Aluminum circuit boards is a metal-based copper clad plate with good heat dissipation function. Generally, the single layer is composed of three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Also used for high tech use is designed as double layers, the structure is circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. A very small number of applications are multi-layer boards, which can be made of ordinary multi-layer boards combined with an insulating layer and an aluminum base.

Aluminum PCB characteristics
● Surface Mount Technology (SMT);
● Extremely efficient treatment of thermal diffusion in circuit design;
● Reduce product operating temperature, increase product power density and reliability, and extend product life;
● Reduce product size and reduce hardware and assembly costs;
● Replace the fragile ceramic substrate for better mechanical durability.

Aluminum PCB use:
● Audio equipment
   Input, output amplifiers, balanced amplifiers, audio amplifiers, preamplifiers, power amplifiers, etc.
● Power supply equipment
   Switching regulator, DC/AC converter, SW regulator, etc.
● Communication electronic equipment
   High frequency amplifier, filtering appliance, reporting circuit, etc.
● Office automation equipment
   Motor drive, etc.
● Automotive
   Electronic regulator, ligniter, power controller, etc.
● Computer
   CPU board, floppy disk drive, power supply unit, etc.
● Power module
   Inverter, solid relay, rectifier bridge and so on.
● LED lighting
   With the promotion of energy-saving lamps, various energy-saving and beautiful LED lamps have been well received by the market, and aluminum PCB used for LED lamps have also begun to be applied on a large scale.
