Microphones

Microphone Types

There are two main types of microphone structures. It is important to choose the microphone best suited for the recording situation. For example, a bass drum produces high sound pressure levels, so it’s best recorded using a dynamic microphones.

Microphone Directivity

Different microphones can capture sounds in different directions.

You should try changing the directivity of the microphone according to the recording.

Type Characteristic

Microphones that have no directivity. Convenient when recording the atmosphere in Omindirectional concert halls.

→The built-in microphones of the R-44

Microphones that have good sensitivity toward sound from the front of the microphone.

Unidirectional Convenient to record only a specific sound.

→CS-50 (Stereo), CS-15R (Stereo), DR-80C, DR-50, DR-30

These microphones have the highest sensitivity toward their front and rear.

Bi-directional They can also be used together with a unidirectional microphone in an MS configuration to produce a stereo signal.
