MODEL SM94
UNIDIRECTIONAL CONDENSER MICROPHONE
The Model SM94 is a unidirectional electret condenser mi-
crophone tailored to the instrument miking needs of profes-
sional musicians and sound engineers in both live perfor-
mance and sound recording. Its smooth, flat frequency
response is free of either a "presence peak" or a low-fre-
quency rolloff, making it a perfect choice for all types of musi-
cal instruments. The SM94 is equally at home in sound rein-
forcement 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 speech-
makers who desire a wide, flat response with minimum col-
oration.
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-chan-
nel phantom power supply (PS1A), and 7.6 m (25 ft.) micro-
phone cable (C25J).
