What is 2.4GHz frequency?
The 2.4GHz frequency range is 2400—2483MHz for Industrial, Scientific and Medical band.
What is sampling ratio?
Cause our products adopt digital transmission, we need put the audio to be digital signal on transmitter. Then the receiver sampling the digital signal and put it back to audio signal.
Normally, we have 16kHz,44kHz,48kHz and 64kHz sampling ratio.
The higher sampling ratio is, the better sound quality is, the shorter transmitting distance is.
What is the advantage of 2.4GHz compared to other frequency?
The advantage of 2.4GHz audio systems.
- Anti-interference, digital signal transmitting.
- HDCD sound quality.
- Free frequency range band.
- Matching code on channels . The transmitter and receiver produced by differenct factory, they can not work each other.
What is the application of 2.4GHz wireless products system?
The 2.4GHz audio system is the newest technology for short distance transmitting. The feature are top sound quality (HDCD), high sampling ratio, short transmission distance (it’s about 150 meter without obstacle), the singal can not thead the brick wall and turn the corner , digial singal transmitting to avoid interference. Cause these features your transmitter’s signal can not be sent to others room, also other’s singal can not get in your room. So this is the best choice for education classroom, conference and meeting room, church, tour and factory visiting, simultaneous interpretation and home theatre system on TV etc
Then you could use this products to achieve induction loop system and assistive listening system function.
How to get induction loop system function?
Firstly, assembling a transmitter to the lecturer. Then the lecturer could use a lapel microphone to connect the transmitter. The audience will be assembled a receiver and headphone or earphone. When the lecturer begain to speak, the audience could receive the voice.
Cause the 2.4GHz signal distance is short ,can not thread the brick wall and turn the corner, only the person in the room can receive the signal. Also other’s 2.4GHz signal can not reach your room.
How to get simultanous interpretation function?
The interpreter of language one use the channel No. 1 to transmitting.
The interpreter of language two use the channel No. 2 to transmitting.
Then the audience could choose one of these channel language which you could undertand to listen.
How to select the channel on receivers?
The receiver have two option on channel selection.
1.) Manual selection mode.
For this mode, When you change the channel on transmitter, you need change the receiver to the same channel too.
2.) Automatic selection mode.
For this mode, when you change the channel on transmitter, the receiver could skip to the same channel as transmitter automatically.
However, for this mode, you just could set one transmitter in the same area because the receiver just could follow only one transmitter’s signal.
When you want to set more than two pcs transmitter at the same area, you need use the manual selection mode. You could set one transmitter on channel #1 ,another on channel #2…, then the user adjust to receivers to channel #1,#2,#3….. to listen the channel which you want.
