Microphone, also known as microphone, is an indispensable radio tool in recording studio equipment. The microphones commonly used in recording studios are electric (moving coil type, aluminum belt type), capacitive (DC polarization type), piezoelectric (crystal type, ceramic type). It can be divided into measuring microphone, voice microphone, musical instrument microphone, recording microphone and so on. According to directivity, it can be divided into heart type, heart type, super-heart type, bidirectional (8-shaped), non-directional (omnidirectional) and so on. Each directivity has a radio characteristic. The editor will discuss with you how to choose a recording microphone.
In addition to directional selection, our microphone usually has two functional switches, low cut and attenuation, which are briefly introduced to you. Low-cut: Usually refers to the filtering of audio below 100 hz. Generally, the audio below 100 Hz mostly comes from ambient noise. The filtering of audio below 100 Hz may also lose some details and affect the overall sound effect. Therefore, the low-cut function has switch selection. The users decorate the acoustic ring according to the studio. The situation is decided freely. Microphone attenuation function is generally 10 dB attenuation, according to the unit can understand, this is a sound amplification power intensity switch, its function is to reduce the overall input volume, but also reduce the microphone to absorb audio range. Sometimes the surrounding environment is too noisy, leading to the main voice facing the microphone can not hear clearly, or the voice of the recording object is too loud, leading to the production of explosion, so when the attenuation switch is turned on, the volume intake of the microphone will be reduced, the environmental noise is relatively smaller, and the main voice can be more clearly displayed. Simply put, low cut means turning off the volume below 100 hz, and attenuation means lowering all the volume a little. These small details should be manually adjusted according to our practical acoustic environment.
