DESCRIPTION
The Model 10A microphone can be used in sound reinforcement or re-
cording, to pick up voices or instruments.
Features
•
Tailored frequency response provides intelligibility and crispness of
sound
•
Neodymium magnet for high signal-to-noise ratio
•
Cardioid (unidirectional) pickup pattern suppresses feedback
•
Locking On/Off switch
BASIC RULES FOR MICROPHONE USE
1.
Aim a directional microphone toward the desired sound source (for
instance, musical instrument, talker, singer) and away from undesired
sources (such as loudspeakers or another instrument) (Figure [1]).
2. Locate the microphone as close as practical to the desired sound
source (Figure [2]) for best gain before feedback.
3. Do not pick up the same sound source with more than one micro-
phone. Keep the distance between multiple microphones at least three
times the distance from each source to its intended microphone.
4. Use the fewest microphones possible for the particular application.
5. When extra bass response is desirable, work close to the microphone.
This phenomenon is known as “proximity effect”.
6. Locate microphones as far as possible from acoustically reflective
(hard, smooth) surfaces.
7. Add an external windscreen when additional pop protection is needed:
outdoors in windy conditions or for closeup vocal use.
8. To preserve directional characteristics, do not obstruct the microphone
grille.
