Technical analyze of 2.4G v.s VHF/ UHF
1) Interference and channeling
Yuepu 2.4G is based on principle of one transmit and one receive. 2.4G will automatically choose the tube which is able to pair up like hand in hand.
2) How to use
The transmitter is small and less than 30g which is easy to carry when it is used. Either clip on the shirt or hang on the neck, the user can use it with more freedom. The transmitter without long microphone cable can greatly avoid unconscious traction damage. However, the traditional transmitter is less convenient since it is heavier, bigger size and has to be clipped on belt with long microphone cable.
3) Effect of voice pick up
Digital wireless technique has been used other product for years. Transmission is very steady. Audio process has been reached simulation technique level. Microphone can choose to use long distance or short distance. The product can reach 60m voice pick up if it is installed properly and surround by nice environment. At the same time, the product has put in Yuepu's 20 years core technique that can make the audio louder and clearer. This is the unique technique that other factories couldn't exceed.
4) Management
We will give every teacher a transmitter in school in order to truly overcome "class to class audio teaching system". The teachers can bright their own transmitter to pair up any receiver easily. It saves lots of expense on technical management. However, with traditional wireless technology, every classroom needs to set a fix frequency and only pair specific one transmitter. Due to the more than one teacher use one classroom, using only one transmitter cause more inconvenience.
5)Consumption
The advantages of battery of 2.4 G overweight the battery of traditional transmitter.
2.4G transmitter uses 3.7V Li battery. It can use up to 7-10 hours like the battery of cellphone. And also it is rechargeable. However, the power supply of VHF and UHF is usually 9V dry battery or rechargeable battery which increase the consumption of battery in long term.
6) Market Demand
The teaching amplifying business has experienced wired microphone, simulation wireless PA, frequency shift PA, ect. But those technologies haven't been able to solve the teaching problems, such as the wired microphone constraint teachers and lessen the freedom during in class. And same problems happen in using the simulation wireless PA. The disadvantages of frequency shift PA is more expensive, disappointed effect, small volume, big distortion, and difficult to fix. When we use frequency shift PA, we need adjust parameters according to different environment, which takes lots of work. The schools haven't found a good- match PA system until the 2.4G series comes up. 2.4G series is trendy product as the multi- media classrooms are getting more and more popular. There is a great potential for 2.4 G product to put in practice in order to overcome " class to class"!
