The directivity of KTV wireless microphone!
Directional description The sensitivity of KTV wireless microphones to sounds from different angles is often represented by polar patterns in specifications. In each diagram, the upper part of the dotted circle represents the front of the KTV wireless microphone, and the lower part represents the back of the KTV wireless microphone. Omnidirectional
Omnidirectional has the same sensitivity for sounds from different angles. It is commonly used in recording projects that need to record the entire environment sound; or when the sound source is moving, and it is hoped to maintain a good sound reception; the lavalier KTV wireless microphone that the speaker wears when giving a speech also belongs to this category. The disadvantage of the omnidirectional type is that it is easy to receive the noise of the surrounding environment, and it is relatively cheap in terms of price. Single point
The common single-pointing type is Cardioid or Hypercardioid, which has the best reception effect for the sound from the front of the KTV wireless microphone, while the sound from other directions will be attenuated, which is common in handhelds.
For microphones and karaoke occasions, the extreme of this type is Shotgun. Bidirectional
Bi-directional (Bi-directional or Figure-of-8) can accept the sound from the front and back of the KTV wireless microphone, and there are not many practical applications.
