Boundary Microphones

Similar to other microphones, the boundary microphone is commonly used to record wider audio past a single user, typically beneficial to capture larger rooms full of music or sporting events.

How do they work?
A small omnidirectional mic capsule is placed near the surface of the microphones boundary. This allows it to pick up directional signals of audio much better than a typical microphone.

Features and benefits:
• Can capture sounds from multiple sources
• Inexpensive
• Small and compact, easy to store
• Can record great distances

Where might I use one?
• To capture key moments within sporting events like football, hockey etc.
• Churches
• Large auditoriums
• Theatres
• Movie production
• Home use
