2.4G Wireless Microphone in the Wireless Era

Before getting into the main topic,let's talk about what is 2.4G wireless technology?Note that the following is the official professional explanation given by Google:

What we call 2.4G wireless technology,its frequency band is between 2.405GHz-2.485GHz(science,medicine,agriculture).So it is called 2.4G wireless technology for short.This band is a free band under international regulations,and there is no need to pay any fees to international organizations.This provides the necessary favorable conditions for the development of 2.4G wireless technology.Moreover,2.4G wireless technology is different from the previous 27MHz wireless technology,it works in full-duplex mode transmission,which has an absolute advantage over 27MHz in anti-interference performance.This advantage determines its strong anti-interference and maximum transmission distance of up to 10 meters.In addition,2.4G wireless technology also has a theoretical 2M data transmission rate,double the 1M theoretical transmission rate of Bluetooth.This improves the reliable guarantee for the future application layer.Comprehensive 2.4G,Bluetooth and 27MHz these three commonly used wireless transmission technology,2.4G has its own unique advantages.Compared to Bluetooth,it is cheaper to manufacture and offers higher data transmission rates.Compared to 27MHz wireless technology,which is also free of charge,its anti-interference,maximum transmission distance and power consumption are far beyond.

Simply put.

1.2.4G wireless technology is a wireless transmission technology whose operating frequency is between 2.405-2.485GHZ.

2.Stronger than the traditional FM wireless anti-interference,faster than Bluetooth transmission speed.

3.Therefore,2.4G wireless technology in the transmission distance,anti-interference,power consumption and transmission speed are very~excellent performance!

Since 2.4G wireless technology is so excellent,then the next to say 2.4G wireless microphone must also be very good!

Relative to the traditional wired microphone,the biggest advantage of wireless microphone is"wireless"!Through the wireless carrier connected to the sound source,the use of more convenient,the user does not have to stick to the wire amount of bondage,within a certain range of free movement.(Can't help but want to sing a song here:Forgive me for this life of unruly indulgence love freedom......)

Compared to FM wireless microphone(commonly known as U-band and V-band wireless microphone),2.4G wireless microphone battery power consumption is very small,a charge can be used continuously for 4-6 hours,power shortage?There is no such thing!

At the same time,two-way 2.4G short-wave frequency hopping technology,radio automatic scanning,address to code matching,you can easily realize any match,truly realize"a teacher a wheat",simple operation,no longer cumbersome,and more importantly,no crosstalk!

Next,let's talk about a few important parameters of 2.4G wireless microphone:

1.Sampling rate:48KHZ

Commonly known as the sampling frequency refers to how many sound signal samples per second collected by the computer,at this time it is describing the sound quality of the sound file,tone,measure the sound card,the quality standard of the sound file.

8KHZ is the sampling frequency of the phone,for people to speak has been enough.And we use 48KHZ,is miniDV,digital TV,DVD,DAT,movies and professional audio used in the digital sound used in the sampling rate,the audio reproduction is very good,the sound quality is not distorted,to achieve the sound quality lossless transmission.

2.Frequency hopping mechanism

This 2.4G wireless microphone has 26 channels that automatically skip to avoid interference.Simply put,as we usually say,4 lanes,8 lanes,maximum diversion and prevent traffic jams.26 lanes of automatic skipping,you can perfectly avoid interference!The same site,the simultaneous use of multiple devices do not crosstalk!

3.Delay:12.5ms

That is,the sound from the launch to the reception of the time difference.2.4G wireless microphone has a transmitter and receiver supporting the use.Subtle to 20ms delay,the human ear is almost imperceptible,professional level!Easy to achieve voice synchronization.

4.Transmission distance

Barrier-free straight line distance of 20-50 meters,i.e.,ideal conditions(without any interference).

Effective distance of 15-20 meters,that is,the existence of wireless devices such as cell phones,routers,Bluetooth devices and other wireless equipment interference,while including walls,obstacles and other interference conditions.

Large conference room,large classroom,outdoor speech,no pressure!

5.Automatic pairing

Turn on the transmitter and receiver at the same time,it can be paired automatically,no need to set up manually,after successful pairing,the indicator light will change from blinking to always on,say goodbye to cumbersome!

At the same time,this 2.4G wireless microphone has applied for the appearance of the patent,the original factory genuine,patent guarantee!Please recognize comtang 2.4G wireless microphone!
