How to choose the wireless gooseneck anchor microphone and handheld microphone scheme

2022-04-23 16:37:00 Tianhui Micro Technology

When choosing wireless gooseneck, anchor and other handheld microphones, anti whistling is an important consideration for users , In fact, it's just that the voice is not clear enough , Distortion when loud . Of course , For wireless microphones , Endurance is also an issue to consider . For the above problems , Tian Huiwei Technology has launched a program suitable for gooseneck anchor wheat U Segment microphone scheme . The scheme adopts Kunteng KT06X series . Its functional features are as follows :

 Gooseneck wheat

ALC+ACG function

Automatic level control (ALC) You can dynamically adjust the effective value of the output voltage when playing audio , It can increase the volume of the whole signal without clipping distortion of wave crest . Audio AGC Is the audio automatic gain control algorithm , It is a mechanism that automatically and dynamically adjusts the gain according to the level of the input audio signal .ALC and ACG Can effectively improve ADC The dynamic range of , Optimize small signal manic low , Avoid large signal distortion . For gooseneck at the meeting 、 Anchor microphone when the anchor speaks with other handheld microphones , It can effectively solve the problems that it is not easy to speak in a low voice and it is easy to be distorted in a loud voice .
 The signal

Audio detection function

Built in audio detection function , Reduce complex peripheral detection circuits . This not only effectively saves the cost, but also ensures the power consumption and controllability of the module . Automatic mute control can be carried out according to RF signal , With automatic mute function 、 Auto off PA、 Automatic shutdown function .
 Auto mute

Squeal suppression function

The howling caused by the positive feedback of microphone and horn is objective , The scheme integrates howling printing . Automatically detect the howling frequency point , Squeal suppression notch frequency point 16 individual , The depth of squeal suppression trap is adjustable , Adjustable width .
 Anti howling

Equalizer (EQ)

Equalizer is a tool that can divide and adjust various frequency components and amplify a large number of audio signals , Through the adjustment of audio signals with different frequencies, the defects of loudspeaker and sound field can be compensated , Compensation and modification of various sound sources .EQ Each filter in the module can be enabled independently 、 Set the center frequency 、 gain 、Q Value and filter type . Optional 15 paragraph , Each paragraph ±12db Adjustable .

The functional features described above are suitable for gooseneck wheat , Work under the characteristic environment such as anchor wheat . In fact, in addition to the above functions , The scheme also has true diversity wireless reception, which is suitable for mobile applications , Such as teaching microphone . For the environment requiring full duplex intercom , It can be used to meet the full duplex mode KT1605 To achieve .
