1.The types of traditional microphones mainly include condenser microphones and dynamic microphones.
The condenser microphone is characterized by high sensitivity, a very wide frequency band, low nonlinear harmonic distortion, and high maximum sound pressure level. Disadvantages are poor mechanical strength, poor moisture resistance, polarization voltage, and troublesome use.
The dynamic microphone is characterized by reliable and convenient to use, no external power supply, good mechanical performance, long life and low price. The disadvantage is that the sensitivity is slightly lower and the frequency response is poor. If a microphone is installed on the microphone head, it becomes a wireless microphone. Flexible and convenient for mobile use
Recording conversations indoors, generally using a
dynamic microphone, because the frequency band of the conversation is narrow,
using a dynamic microphone can avoid unnecessary noise. For music recording,
you should choose a condenser microphone with good performance to meet the
needs of wide frequency band, large dynamic and high fidelity.
Live performances outdoors, because of the high ambient noise, super-directional microphones can be used to increase selectivity.
When using a microphone, be careful to keep a distance of about 0.3 meters from the sound source to prevent distortion, except for the microphone. For recording in motion, use a wireless microphone. If you need hand-free, you can choose a headset microphone or a lavalier microphone.
When using a wireless microphone, be careful to prevent interference and “no signal zone.” This can be solved by changing the radio frequency, adjusting the transmit and receive antennas, and adding an antenna amplifier.
