Hey, and welcome to HowToAV.tv, my name is Tom Coleman and I’m a senior applications engineer at Shure UK. We’re
gonna look today at some boundary microphones. Boundary microphones are
designed for spoken word applications in AV and conferencing based environments.
Firstly, they’re designed to be placed straight on the table about two feet in
front of the talker. They vary firstly in all sorts of shapes and sizes; from big
ones to small ones, ones that sit flat on the surface, and also these ones that can
be flush mounted within the desk, as you can see just here. They vary in polar
pattern, which means the direction they pick up sound from. The typical polar
pattern will be a cardioid, which looks a bit like that, so they’ll pick up sound
from these directions here. Super cardioid is a little narrower, and
omnidirectional is much much wider and picks up sound from all over the room.
The cardioid boundary mic should be used one per person, but an
omnidirectional boundary mic can be used in the middle of perhaps a small,
circular table. Boundary mics available as wired, or Wireless options too. The wired options make sure the audio gets straight back to the mixer straight away
so can be processed. Whereas the wireless option allows for much more flexible use
in multi-purpose rooms
