The ME33 is a powerful omni-directional microphone designed specifically for recording voices from greater distances. In combination with a professional Olympus dictation machine, the automatic processing of very high and low frequencies produces audio files in crystal clear sound quality. In addition, it offers scalable recording performance: If you connect multiple ME33 microphones using the supplied connector, you can record your recordings as a stereo sound version (with six units) or as a monaural version (with three units).
