BOUNDARY MICROPHONES

 

SAMSON CM11B
Acoustic Boundary Microphone, Omnidirectional

 

This surface mount CM11B condenser mic has an omnidirectional pickup pattern that captures sound in a 180 degree pattern. Its ideal application would be to place one (for up to 6 people) or two (for up to 12 people) on a boardroom or conference table to pick up the meeting. The microphone's low-profile design assures minimum visibility. It has an internal high-pass filter to control low frequencies (that annoying rumble you get when someone in the meeting bangs the table, for instance!) and it comes with a 30-foot cable terminated with a mini-XLR at the microphone end and a standard male XLR at the recorder end. It requires 9-52V Phantom Power from the recorder. Whilst the CM11B is not as capable as the Beyer Dynamic MPC66 above it delivers a pretty presentable performance at the price - certainly more than good enough for transcription purposes.

SAMSON CM10B
Acoustic Boundary Microphone, Unidirectional

 

This surface mount CM10B condenser mic has an unidirectional (half-cardioid) pickup pattern making it perfect for more focussed applications where an omnidirectional mic may be too open (e.g. in noisy environments). It is therefore perfect for oral history or similar interviews when a conventional stick microphone on a table stand might inhibit the interviewee. The microphone's low-profile design assures minimum visibility. It has an internal high-pass filter to control low frequencies and it comes with a 30-foot cable terminated with a mini-XLR at the microphone end and a standard male XLR at the recorder end. It requires 9-52V Phantom Power from the recorder.
