What is true about the lavalier microphone?

The lavalier microphone is designed for hands-free operation, making it an ideal choice for situations where the speaker needs to move freely without carrying or holding a microphone. It is typically clipped to the clothing of the speaker, allowing for a discreet and unobtrusive way to capture audio. This feature is particularly beneficial in stage productions, interviews, or presentations where the speaker engages with an audience or moves around the performance area.

The other options present misunderstandings about the lavalier microphone's characteristics. Instead of being bulky and visible, lavalier microphones are often compact and designed to blend in with the wearer's attire. They also do not require a complex setup; in fact, they are often user-friendly and can be quickly attached to an outfit. Lavalier microphones can be dynamic or condenser types, but they are not static in functionality. Thus, the emphasis on the hands-free capability accurately highlights the primary advantage of using a lavalier microphone in various audio and performance settings.
