How to provide power to a lavalier microphone?
Many users see TV programs that use the Lavalier Microphone to sound very well and have also used the microphone to amplify the sound in the field with less than satisfactory results. This is not the Lavalier Microphone itself quality problems, but because the microphone is worn too far away from the mouth, the microphone in the field when the microphone with the speaker system speakers produce feedback sound physics, can not arbitrarily increase the volume, so the PA not effectively.
Reduce the distance between the microphone and your mouth to improve the sound amplification of the microphone:
As the Lavalier Microphone worn on the chest, away from the mouth, the output volume will be greatly reduced, if the amplifier volume is large, it is easy to produce audible feedback, which is generally the microphone user often encountered problems. If you want to enhance the microphone volume, but also produce no feedback, the only way is to use the "microphone volume and the source inverse square inverse distance" principle, the microphone and the mouth of the distance closer to the microphone can be greatly louder The promotion.
BY-LM400 Dual-Lavalier Microphone
The BOYA BY-LM400 is a dual-lavalier microphone is designed for recording interviews. With 3.5mm(1/8") TRRS connector, it works for iPhone, Ipad and most of Android devices.
It uses a TRRS connector to connect into your smartphone or tablet's headphone input
And With 4m (13') Cable, the BOYA BY-LM300 can be used for presentations, podcasts, webcasts, or any situation where more than one subject needs to be recorded.
Adjusting the position of wearing the microphone and adjusting the sound head at the position of "near both the left and right of the mouth" can reduce the noise of the gas explosion and obtain the desired sound volume and normal sound quality.
Headphones used in the headset are: omnidirectional and unidirectional two, the former, because the first non-directional head, when worn as long as the "tune the sound on both sides of the mouth, from the mouth about a finger distance, And close to the mouth perpendicular to the direction of ", you can obviously avoid gas explosion noise, to achieve the clearest sound.
After the actual test, "the microphone head and mouth to keep the front of a finger about the distance between the mouth and keep a 45-degree horizontal direction" is the ideal position to wear, to avoid the destruction of gas explosions, but also to show Optimum sensitivity and sound quality, if the sound head position than the front corner of the mouth, by the impact of the sound of the explosion will be greater, although the use of windshields such as sponge, you can slightly reduce the impact of air noise and wind noise, but how much Will also undermine the face of view and attenuation of the high-frequency response of the microphone.
