Olympus ME-33

Boundary Microphone. The ME33 is a powerful, omni-directional microphone that is purpose-built to record voices from a distance - even in the largest conference rooms. Combined with an Olympus professional voice recorder /not included/, it consistently produces audio files in crystal-clear sound quality by automatically cutting extremely high- and low-frequency sounds. It also gives you scalable recording power: By connecting up multiple ME33 microphones using the bundled connector, it is also possible to produce a stereo sound version (with six units) or a monoaural version (with three units) of whatever you wish to record.
