Shure 14A Manual Del Usuario

DESCRIPTION
The 14A microphone can be used for karaoke, in sound reinforcement
or recording, to pick up voices or instruments, indoors or outdoors.
Features
Tailored frequency response provides vocal intelligibility and crispness
Neodymium magnet for high signal-to-noise ratio
Shock mount reduces handling noise
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, talker, singer, musical instrument) 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.
3. Do not pick up the same sound source with more than one microphone.
Keep the distance between multiple microphones at least three times the
distance from each source to its intended microphone.
4. Use the fewest microphones practical 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. Avoid excessively handling the microphone to minimize mechanical
noise pickup.
9. To preserve directional characteristics, do not obstruct the grille with your
hand [Figure 2].
