PA Speaker shift occurs Bluetooth device frequency hopping spread spectrum communication technology, digital transmission technologies such as voice encryption 2.4G digital wireless microphone successful solution to the traditional wireless microphone frequency channeling problem of poor anti-interference ability and mini- and so we have done an innovative attempt. Let's look at 2.4G digital microphone is how to meet the special needs of the education sector. The use of intensive study and education to meet the requirements of: a microphone to work on 2.4GHz (ISM) radio frequency band, modulation / demodulation process is fully digital. Encrypted transmission technology, has strong anti-interference, versatility and good. Each device has a unique ID code to hide ceiling conference speakers, ID coding up to 100 million units, the complete elimination of the traditional analog wireless microphone frequency channeling phenomenon. Green: The figure is a drop-type and T-type wireless microphone microphone, using low-power transmitters (1 mW), is an international standard of 1/10. Just so that the radio signal covers the entire range of conference speakers classroom to avoid a long time in strong electromagnetic radiation environment on human health. The use of reusable rechargeable lithium battery authentic original conference speakers, reducing damage to the environment after use disposable batteries, is a true 'green wireless microphone'. Weird, in short, the school and the outside is not the same. It determines a band, and it must be considered rehearsal equipment, apparently a speaker simulator is not enough, at least more than a 1500 speakers. Devaluation cube30. Because of this nothing is enough. If you can meet other hand fender or marshal l What must seize the opportunity of the conference speakers wall mounting, 2000 to 4000 blocks can buy the box. (Our bass box is so bought) if more bands, preferably with a speaker simulator, particularly convenient. Into the mixer can be used. To talk about it on a single block, the simulator and then cattle, it is impossible to issue a really good spot to hear that sound. That sound can only get by real tube amp Conference Speaker pray for the earthquake, Wuhan Jiuhua video (certified), conference speakers are provided by Wuhan Engineering Co., Ltd. Jiuhua video.
