Classical guitar is a very beautiful instrument, however, the sound transmission problem of the classical guitar performance scene has always restricted the live performance of this instrument, so that it can only be performed and appreciated in the form of a salon concert on a smaller occasion, of course, this does not hinder her beauty and charm.
The traditional way of receiving, no matter how good the condenser microphone, is in a passive way, to receive the sound of the classical guitar, in addition to the electric box pickup, or patch pickup, always have the taste of electro-acoustic, can not achieve a complete sound restoration, if the sound of the classical guitar, spread out of the sound becomes electro-acoustic, everyone will feel that the classical guitar has lost her most charming original taste.
Also, the ensemble of classical guitar orchestras, ensembles with other instruments, a large number of people, it is particularly troublesome, when a mixer, connected to several condenser microphones, the pickup interference between the condenser microphones, as well as the microphone line full of stage, is enough for the tuner to scramble.
In view of the difference between the classical guitar and the modern popular guitar audio curve, many so-called high-end expensive microphones, but the dynamics of the sound is higher, these high-end microphones, the expansion of technology is to show a lower sound and a higher sound dynamic range, and the classical guitar range and frequency sound curve, does not need this can receive such a high dynamic range of full-frequency sound range equipment, this equipment for classical guitar pickup transmission, is really unable to open hands.
The most professional way to use the equipment used in classical guitars is to simply point to the design of the frequency response curve of classical guitars, which is professional and feasible.
Teacher Liu Jun, who has been committed to the popularization, popularization and stage education concept of classical guitar for many years, usually has a hobby of studying audio and video, and this hobby of classical guitar audio and video recording has made him have ideas, making him a classical guitar professional who rarely pays attention to classical guitar microphones and sound reinforcement equipment in China.
In 2019, rather than a rare chance encounter, it is better to say that it is a rare opportunity for Teacher Liu Jun to develop a special microphone designed specifically for classical guitars, so that In The efforts of Teacher Liu Jun, but also with the appeal and persuasiveness of his own personality, and Aishangda Electronic Audio Equipment Co., Ltd., reached an agreement to launch a wireless transmission and reception system specifically for classical guitar audio curves, named AT5 Classical Guitar Dedicated Wireless Transmission and Reception System.
Teacher Liu Jun's first idea of this finished product is completely correct: AT5 classical guitar special radio microphone, is an active condenser microphone, rather than like most of the microphones seen, is the kind of passive reception of sound, the advantage of this active microphone, is low cost, do not need to pick up from the passive like, in order to be good so little, it will increase a lot of cost, and also need to invest a lot of technical research and development, active microphone does not pick sound reinforcement sound equipment, It also avoids the problem of sound whistling to a greater extent.

AT5 classical guitar special radio microphone after the launch, Liu Jun teacher is still very cautious and careful, for Liu Jun teacher, a product that has not been widely used verification, immediately launched on a large scale, this is very irresponsible to classical guitar lovers and players, this product must be evaluated in practice, withstand various situations, in line with his original intention. Therefore, the first batch of only 100 microphones were produced, through Teacher Liu Jun, to the hands of senior classical guitar educators and performers and guitar teachers, such as Zhao Changgui, Wu Zibiao, Chen Xi, Tang Keyong, Li Mingbo, etc. After their testing, the actual experience of this microphone is still relatively satisfied, especially valuable is that these friends of Teacher Liu Jun sent the live video of the use of this microphone to Teacher Liu Jun through WeChat, so that Teacher Liu Jun's evaluation of this microphone can get a real and specific evaluation.
As a new product, THE5 classical guitar microphone is not perfect, after 100 tests and evaluations of 100 people, it also raises a lot of small problems, so, in the use and pickiness of many experts, this AT5 classical guitar microphone has been improved by three generations, basically becoming a more mature product.
In 2021, Liu Jun and the manufacturer after meticulous and cumbersome communication, based on the maturity of AT5 technology, developed a special AT6 classical guitar microphone specifically for the classical guitar mobile phone recording live broadcast system. This small microphone poured out almost all of Liu Jun's ideas and all the technical capabilities of the manufacturer.
In view of the more professional needs, on the basis of AT6, a more high-end AT8 classical guitar microphone was specially created, which achieved a perfect match between medium and high.
