Which microphone for which purpose?

Different microphone types

Anyone who wants to begin recording instruments will ask themselves which microphone(s) they should buy. The overwhelming choice doesn’t help, either. We’d like to help you through the labyrinth with a short description of the different kinds of microphones, with their applications and directional properties.

Types of microphones

Dynamic microphone:

In a dynamic microphone a coil is moved within a magnetic field, inducing a current. This converts sound pressure into an electrical signal. There are two types of dynamic microphone..

  • Moving coil microphone: Its name comes from the technical arrangement of its elements, where the magnet coil “moves” within the magnetic field.
  • Ribbon microphone: The ribbon microphone uses a diaphragm of thin, corrugated aluminum placed between two magnets.

Condenser microphone:

In a condenser microphone the capacitor comprises a diaphragm and a metal plate. Vibrations change the distance between the diaphragm and the plate, creating a capacity which is converted into an electrical signal. There are two types of condenser microphone.

  • Large diaphragm condenser: Has a diaphragm diameter that is larger than the standard 2.54 cm.
  • Small diaphragm condenser: Has a diaphragm diameter that is smaller than the standard 2.54 cm.

Applications + advantages and disadvantages

Dynamic microphones are robustly designed (apart form ribbon microphones) and thus are particularly suitable for live performances. They can sustain impacts and falls, but aren’t designed for low and soft signals because of their restricted sensitivity. They’re great for live vocals, guitar, snare, bass drum and brass. No external power supply is needed when using a dynamic microphone.

Large diaphragm condenser microphones are more sensitive and therefore ideal for studio use. They’re high-resolution and are used for vocals, guitar, flute and room sound. A power source known as phantom power is required for using this microphone.

Small diaphragm condenser microphones have a more neutral sound as a result of their smaller diaphragm and respond better to higher sound pressure. However, they have higher self-noise. These microphones are often used for strings, flute, acoustic guitar and as an overhead microphone for drums. They require phantom power.

Ribbon microphones belong to the dynamic microphone family, but are used less frequently in production, because they are very expensive and are very delicate because of their design, as described above. Fans of ribbon microphones enjoy using them for their soft, warm sound, ascribing a certain magic to their sound. Strings, wind instruments and guitar amps sound full and round. For the majority of recordings, these microphones don’t require phantom power.

Directional properties

Every microphone has its own directional properties. This describes the microphone’s sensitivity to sound depending on the direction it’s coming from. As this is an important criteria for use, it’s good to be informed about this before buying. The standard properties are briefly described here:

Omnidirectional: Picks up sound evenly from all directions. Microphones with this property are not suitable for live performance because there is a high risk of feedback. Clip-type mics like those on talk shows are omnidirectional.

Visualisation omnidirectional

Cardioid: Sound is picked up mostly from the front, and from the back to a much lesser extent. Because they’re less susceptible to feedback, they’re ideal for live applications.

Visualisation cardioid

Supercardioid: Sound is picked up even more precisely from the front. However, a supercardioid microphone also picks up sound from the rear, so take care to position the monitors in the right place.

Visualisation supercardioid

Bidirectional: Sound is picked up in equal measure from the front and back, but only minimally from the sides. Ribbon and large diaphragm condensers in particular have this sound pick-up pattern and can be used when two singers are facing each other or between two toms.

Visualisation bidirectional
