The wireless microphone is composed of a number of pocket transmitters (which can be installed in a pocket, the output power is about 0.01W) and a gathering receiver. Each pocket transmitter has a different working frequency. The gathering receiver It can receive voice signals of different working frequencies from various pocket transmitters together. It is suitable for occasions such as stage podium.
The basic concept is to choose the model that suits your needs. The types of wireless microphones can be distinguished into many different types according to different definitions. Wireless microphones: commonly known as FM refers to the FM 88-108MHz international frequency modulation broadcasting frequency band. Early consumer wireless microphones were received using FM radios. The system was simple and cost-effective, but because of the application.
Unable to meet the requirements of professional quality, the 21st century can only become a toy for children or students. Wireless microphones are divided into two types: low frequency and high frequency. The former uses the VHF50MHz frequency band. Due to the low frequency, the antenna length is too long, and the most Easy to be disturbed by various electrical clutter, so this type of product.
In the 21st century, it has been replaced by high frequency bands and gradually disappeared from the market. The latter uses the VHF200MHz frequency band. Due to the higher frequency and shorter antenna, it can even be planned as a hidden antenna, which is convenient, safe and beautiful. The clutter of the receiver is greatly reduced, the circuit planning is extremely mature, and the parts are available in price. It is cheap, so it has become a popular model in the market today.
