The Sony ECM-CR120 is a miniature omni-directional lavalier microphone designed for capturing audio in meetings, lectures, conferences and more. The microphone features a control box which houses the AA battery used to power the microphone. The box also serves as a mount for the microphone, allowing placement on desk surfaces for conference style audio capturing. The omni-directional polar pattern captures audio evenly at the direct and off-axis sections of the microphone. Advanced noise reduction technology effectively rejects ambiance and noise. A sensitivity switch enhances the microphones signal response.
