The Model SM94 is a unidirectional, electret condenser microphone tailored to the instrument miking needs of professional musicians and sound engineers in both live performance and sound recording. Its smooth, flat frequency response is free of either a “presence peak” or a low-frequency rolloff, making it a perfect choice for all types of musical instruments. The SM94 is equally at home in sound reinforcement systems or in sound studios and motion picture/TV scoring stages. When used with the optional windscreen, the SM94 can be used by vocalists and speechmakers who desire a wide, flat response with minimum coloration. The SM94 can be powered by any phantom power source, or by an internal 1.5-volt AA battery. The battery, which serves as a backup power source in the event of phantom power failure, can provide up to 5,000 hours of continuous operation. The SM94 is supplied with a swivel adapter for use on a microphone stand, boom or gooseneck, and a zippered vinyl storage bag. Model SM94-LC is supplied without a cable. Accessories include a foam windscreen (A3WS), two-channel phantom power supply (PS1A), and 7.6 m (25 ft.) microphone cable (C25J).
