Condenser microphones are much more fragile than dynamic microphones, but usually have a wider frequency response which gives a more accurate sound reproduction. They use a small electronic capacitor to convert the sound waves into a signal. They are also much more sensitive than dynamic mics and can therefore be used at a greater distance from the sound source; for example, where a discreet microphone is needed at the edge of the stage to boost an actor’s voice.

They are usually directional, so still must be facing the sound source. They are usually recognised by being longer and thinner than a dynamic mic, and are sometimes known as ‘rifle mics’ due to their appearance. However, condensers can also include hand-held condenser mics, similar to dynamic vocal mics, or miniature clip-on presenter’s mics.

Condenser microphones require a power source to operate - in a professional environment this is generally provided via Phantom Power, although some microphones may be able to utilise batteries in order to operate with an unpowered source.
