How to buy wireless microphones and ktv microphones?

Author:admin   AddTime:2021-11-09

Before purchasing wireless microphones and KTV microphone products, you must first have a basic concept of the product category, so that you can choose a model that suits your needs. According to the definition, the categories of wireless microphones can be divided into multiple types.

A. FM wireless microphone 3360 is usually called FM, which refers to the FM 88-108MHz international frequency broadcasting band. Early consumer wireless microphones used FM radios to receive them. The system is simple and the cost is low, but because the use effect cannot meet the professional quality requirements, the 21st century can only become a toy for children or students.

B.VHF wireless microphones are divided into low frequency and high frequency bands using the VHF50MHz frequency band. Due to the low frequency and the long antenna length, it is susceptible to various electrical noises. Therefore, this type of product was replaced by the high frequency band in the 21st century and gradually disappeared from the market. The latter uses the VHF200MHz frequency band with high frequency and short antenna. Therefore, it is designed as a hidden antenna, which is convenient, safe and beautiful, and greatly reduces clutter interference in electrical appliances. The circuit design is very mature and the parts are popular and cheap, so it has become popular in the market today. The models can be used for KTV microphones.

C. UHF wireless microphones use wireless microphones with a frequency of 300-3000 meters. It is the mainstream of microphone applications in the 21st century. The stability has been greatly improved because of avoiding interference such as v-zone radio.

Method distinction

A. Quartz locking model: It uses a quartz oscillator to generate an accurate and stable fixed frequency. The circuit is simple and the cost is low. It is the standard circuit design of today's wireless microphones. This type of microphone can only be fixed in a single frequency pair, and the frequency of use cannot be changed or adjusted.

B. PLL Synthesized models use the circuit design of PLL to meet the requirements of these functions, because wireless microphones cannot be used to avoid interference from other signals during use, or they need to be easily and quickly changed at any time. Use multiple microphones at the same time.

According to A. The single-channel model only has a non-automatic or automatic selection of only one channel assembled in one chassis. Electronics has almost no market in Taiwan, but the export market is low in price, so it is a (bulk commodity). The latter is simple to use and has stable characteristics. It can use multiple channels at the same time in professional places and is a good model to prevent signal interference. b. The dual-channel model 3360 assembles non-automatic or automatic selection of two channels in one chassis to maximize the use of chassis space and reduce costs. Electronic is the so-called "Asian fighter" model. Because of its simple design, it has become the main model of low-cost manufacturers in Taiwan. The latter can only be used by a small number of companies that produce professional models due to the complexity of the mechanism and circuit, and the difficulty of internal interference processing and antenna mixing. C. Multi-channel models assemble more than 4 in one chassis, and most of them adopt the mechanism design of modular receiving module. Mainly suitable for the use of professional rack models.

According to the way of use, KTV microphones are still relatively common. Many entertainment venues and business promotion will use KTV microphones. So KTV microphones are quite common.

The above are the types of wireless microphones and KTV microphones. If you need them, you can contact us.
