Omni-directional microphones typically capture sound from all directions, including unwanted background noise. In contrast, the MD 46 cardioid interview microphone is tailored to concentrate on the subject, enhancing clarity and minimizing background distractions. It's specifically engineered to produce low handling and wind noise, and to prevent vocal popping. This makes it an excellent tool for Electronic News Gathering (ENG) teams looking for clear and focused audio in their interviews.
