4. correct polarity to wake up the battery Power on again Rear cap has an On Off switch protection The patented color rear cap serves two purposes it provides easy channel identification and protects the on off switch It is designed to allow the on off switch to either be exposed or concealed as desired You can avoid unintended switching off of the microphone by rotating the color rear cap 180 degrees to cover the on off switch completely The cap can be removed by gripping it firmly and pulling be sure to push it firmly into place when replacing it on the microphone NOTE During microphone usage the color rear cap must be installed Turn rear cap 180 degree and insert back ON OFF is covered 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 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
5. 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 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 4 Furthermore a large diaphragm directional microphone has a very distinct proximity effect When the microphone is close to the mouth the bass response is strengthened as the distance gets closer Therefore if a performer s sound is insufficient in bass they can hold the microphone closer and use the proximity effect to help compensate for the lower bass level Conversely if a performer s voice is too heavy in the bass register increasing the distance between the microphone and their mouth will decrease the proximity effect and reduce t
