Line microphone

Types of Line Microphones

A line microphone is useful for recording audio from instruments like guitars or other sources such as a line-out from a mixer. It is also called a direct injection (DI) box. This mic transfers the signal to a different format (electronically), so it can run through a typical microphone cable to the mixing console. This kind of mic can be categorized into two types: the dynamic microphone and the ribbon microphone.

• Dynamic microphone: The dynamic line microphone is robust and versatile, making it an excellent choice for various recording environments, whether studio-based or live performances. It works by converting sound waves produced by the speaker's voice into electrical impulses using a diaphragm attached to a coil of wire, all within a magnetic field.
• Ribbon microphone: The ribbon line microphone has a vintage appeal that many audio enthusiasts adore. It uses a thin metallic ribbon, usually made of aluminum or steel, to convert sound waves into electrical impulses. When sound waves hit the ribbon, it moves within a magnetic field, and the resulting electrical signal is transformed through a connector.

Functions and Features of Line Microphone

Below are some of the common features of a line microphone, which may vary depending on model and manufacturer.

Features

• Sensitivity

  The line microphone is highly sensitive and can pick soft sounds. This mic can amplify even the slightest sound, making it ideal for professional and studio recordings, musical performances, and sound design.
