Dynamic Microphones

When you are rocking out on stage or delivering any type of active, high energy performance you need a microphone that can withstand the pitfalls of live music and still put out quality sound. Dynamic microphones are built sturdy enough to weather the more chaotic aspects of live performance while still capturing your amazing sound.

What is a dynamic microphone?

A dynamic microphone converts sound into an electronic signal through electromagnetism. The most common type of dynamic microphones feature a moving coil that slides back and forth on a membrane when hit with sound waves. This movement in conjunction with a stationary magnetic gap induces voltage in the coil, this creating an electric signal.

Unlike condenser microphones, dynamic microphones do not contain components that require electricity, and therefore do not require an external power source in order to operate.

Best uses for dynamic mics

The rugged design and durability of dynamic microphones make them perfectly suited for live performance. The components inside a dynamic microphone are typically sturdy and able to weather the sort of abuse inherent to frequent stage setups and break downs. They are also resistant to moisture and therefore ideal for high energy vocal performances that may deliver—well—a bit more than just vocals! Overall dynamic microphones can simply take a large amount of rough use and still deliver the same quality of sound as they did right out of the package.

Dynamic microphones may not be as accurate or provide the same range of frequency as other microphones, but this tends to make them even more ideal for live performances. While studio recordings are meant to be scrutinized and carefully crafted for the best possible result, live performance is raw and experienced in the moment. Extremely accurate sound is somewhat irrelevant when you consider that the true heart of live music is energy and authenticity.

The lack of sensitivity in dynamic microphones means they are much better at capturing the loudest aspects of live music, such as noisy guitar amplifiers, drums, and live vocals.

Dynamic mics vs. condenser mics

While dynamic microphones are built to be sturdy and forgiving, condenser mics are more fragile—but also better suited to delivering studio-quality sound. Condenser mics feature a more delicate diaphragm mechanism that can capture wider frequencies for accurate results but are also more susceptible to loud noises. They are great in controlled studio environments, but typically just don’t hold up to the more chaotic aspects of a live stage. Dynamic microphones can also withstand significantly more physical abuse than condenser mics.

Dynamic microphones are also preferred on stage due to the fact that they don’t require any external power. Most stage technicians would much rather deal with non-powered dynamic microphones than worry about whether a condenser microphone is currently receiving the appropriate power required to operate.

Condenser mics are also generally more expensive than dynamic microphones. This is another reason why they are more suited the studio as opposed to the stage, where their strengths become less relevant.
