General Tips for Improving System
Performance
1. Performer should avoid holding the microphone over
or near the antenna section as this will deteriorate
transmission efficiency. Severe deterioration if
performer directly covers up the antenna section with
both hands.
2. Many performers tend to hold the microphone by the
top grille. Unfortunately, this position seriously
degrades both the sound quality and directionality of
a microphone. Even the most expensive microphones
will have its original sound quality compromised by
this method. Grabbing a microphone by the grille will
isolate the capsule's acoustic resonance circuit and or
change the capsule resonator's frequency. This
results in an inferior performance in both frequency
response and the separation of directionality. In
addition, a palm's sound-focusing effect will tend to
strengthen resonances in certain frequencies and can
cause unwanted echo.
3. A proper technique is required for using directional
microphones because the distance between the
microphone and your mouth has a significant impact
on sensitivity and performance. There is an inverse
relationship between microphone sensitivity and the
distance from the mouth to the microphone.
Consequently, performers with a ''weaker'' sound
level cannot expect to hold the microphone too far
away from their mouth and compensate by turning
up the amplifier volume to increase the sound level
as this can easily cause echo or feedback. In
contrast, performers with a ''louder'' sound level
should not hold the microphone too close as this can
easily result in distortion by causing the amplifier
system to be overloaded.
