Microphone Types and Their Uses for Broadcasting

Microphone Types and Their Uses for Broadcasting

One of the best inventions of modern science is the microphone. There are many different types of these little wonders, each crafted for a specific purpose. Some are designed for musical instruments, others for vocals and others are multi-purpose.

Broadcasting microphone features

Broadcasting microphones are used in radio studios and are ideal for announcing and voiceovers. Virtually all broadcast mics have some similar features that they share:

  • Cardioids pickup pattern – this rejects noise off axis, and the microphone will only pick up the sounds desired
  • Shock-mounted capsule – it prevents noise resulting from vibration or handling of the microphone
  • Integrated pop filter – it protects the capsule from sibilance when one speaks close to the microphone

Types of microphones

Electro-Voice RE20

This microphone has been in use for over 40 years, and there is no sign of it slowing down. It is popular for its rich low-end response, making it ideal for vocals. Its directional pickup is effective and the response of the frequency is close to being independent of an angular orientation of the mouth of the speaker.

This means one can move around with it without any significant change to the vocal tone. If the buzz or low-frequency rumble begins to get out of control, a switchable high-pass filter will compensate.

There is an external pop filter to offer protection against plosives. It also has a shock mount that is unique and dedicated to the mic. You can buy the Electro-Voice RE20 as a convenient kit that includes;

  • XLR cable
  • Articulating boom arm
  • Raiser and shock mount

Rode Broadcaster and Procaster

These two mics are similar in features and designs. The difference is that the Broadcaster has large diaphragm condenser whereas that of the Procaster is dynamic. Due to its wider frequency response, the Broadcaster can be used for applications that go beyond the pickup of voices. Also, it comes with a built-in “On Air” light to show when it is active.

The Procaster and Broadcaster are excellent vocal mics used for broadcasting. The broadcaster can be bought as a kit and includes an XLR cable and an external pop filter.

Neumann BCM-104 and BCM-705

These two mics are similar with the BCM-705 being dynamic and the BCM-104 being the condenser. Their frequency response is 20Hz – 20 kHz. The pickup pattern of the BCM-705 is hypercardioid, and that of BCM-104 is cardioids.

Thanks to the sensitive design of the

 BCM-104 capsule, you will be able to get more vocal clarity when using this mic. A useful feature of both mics is the capability to change the head grille. This means you can switch them between users or remove the grilles to clean them.

Shure SM7B

The Shure SM7B is one of the most popular dynamic condenser mics and has been designed specifically for vocal broadcasts. The large diaphragm delivers frequency response that is flat so you can get a true reproduction of the vocals.

You can tailor the sound to meet your needs using the switches for midrange enhancement or bass roll off. Additionally, the Shure SM7B is highly resistant to the electromagnetic hum caused by bad grounding or electronics. For close-up and normal use, the SM7B includes A7WS and RK345 windscreens.
