SGM-12 — Shotgun Condenser Microphone
Congratulations on purchasing the Nady SGM-12 Shotgun Condenser Microphone! This versatile, professional
quality microphone is designed to provide top performance in all live and recording applications. Its true,
transparent sound also makes the SGM-12 a valuable recording tool.
SPECIAL FEATURES
• Perfect for video recording, lectures, angled overhead placement, boom applications and off-stage miking
• Dual electret condenser elements for maximum uni-directivity with excellent off-axis rejection
• Power / Polar Pattern switch for selecting cardioid or super-cardioid sensitivity
• Smooth linear response with high sensitivity and exceptionally low self-noise
• Sleek, durable, lightweight metal construction
• Single AA alkaline or NiMH battery operation (not included)
• Extra thick foam windscreen included
• Optional HM-9 mic clip and SHM-1 shoemount available for mounting on mic stands or camcorders
USING YOUR SGM-12
The SGM-12 can be used with any standard mixer, powered mixer/amplifier, mic preamp, or video camcorder. Using
the appropriate cable (not included) connect the female XLR end of your cable to the SGM-12, and the other end to
your equipment.
Depending on the application, the SGM-12 can either be handheld, mounted to a camcorder, or mounted on a microphone stand with a standard mic clip.
Be aware of the proximity effect (an increase in bass response) when the mic is placed closer to the sound source.
This may or may not be desirable. Experimenting with the position of the mic with respect to the audio source will
ensure the optimum results you are seeking in any given application.
If the microphone is placed too near a speaker, an unpleasant howling effect (acoustic feedback) may occur. Although
all microphones are prone to feedback to some extent, those with a unidirectional or super-cardioid polar pattern
(such as the SGM-12) are specially designed to accept only signals from the audio source directly in front of the mic
cartridge. Thus, the polar pattern of the SGM-12 ensures that it will deliver only the desired audio in front of the mic,
rejecting the unwanted audio from the rear, even in noisy ambient conditions with high sound pressure levels from the
PA. and monitor speakers. This means that feedback will be greatly minimized with the SGM-12 in all live performance
miking applications.
Some useful ways in which to totally eliminate annoying feedback include: experimenting with mic positions with
respect to the speakers, decreasing speaker volume (whenever possible), and adjusting the equalization of the mic
audio with the mixer.

• The microphone should never be dropped or subjected to extreme shock. Store only in a padded case to protect it during transport.
• Keep the microphone away from extremely high temperatures (above 140°F or 60°C )and humidity. Avoid leaving the
microphone in direct sunlight for long periods of time.
• When using the microphone outdoors, avoid getting it wet.
• After use in a high-moisture application such as a stage performance, wipe off the microphone with a dry cloth and
permit it to air dry. Do not store the unit in a closed space (e.g., a plastic bag) until all moisture has evaporated.
• To protect the mic elements and ensure the longest possible useful life, it is highly recommended that for vocal applications, the external foam windscreen be used over the grille. This will prevent the buildup of saliva and perspiration on
the cartridge diaphragm, which degrades performance and shortens the useful life of the microphone. The foam windscreen will also eliminate wind noise when the mic is used in a windy outdoor environment.
