    matters needing attention

    (1) do not hold the net head of the microphones with your hand.

    The receiving part of all microphoness has a certain directivity. If you hold the mesh cover with your hand, the directivity and frequency response of the microphones will be changed. Due to the aggregation effect of the palm, there will be backflow and howling.

    (2) do not hold the antenna transmitting part of the microphones.

    In general, the transmitting circuit and antenna of a handheld microphones are located at the lower part of the microphones (far away from the microphones). When human hands touch the antenna, most of the radio frequency is lost because it can not enter the air, which reduces the application scale of the wireless system and affects the reception effect.

    (3) keep the distance between the microphones and the mouth properly

    When using a handheld wireless microphones, it is better to keep the distance between the microphones and the mouth at 5-10 cm. If the microphones is too close, it will cause proximity effect, and if it is too far away, the sound quality will be damaged. When using the Lavalier microphones, it is necessary to prevent the microphones from being too far away from the mouth, and try to be close to the mouth; when using the headband microphones, it is necessary to prevent the mouth from directly talking to the head of the barrel, so as to prevent the impact of the acoustic airflow Move both ends.

    (4) prevent the microphones from pointing directly at the speaker.

    If the microphones is directed directly at the speaker, the system will form a closed loop, and positive feedback (howling) will occur, which is necessary to prevent.

    (5) prevent two wireless microphones transmitters against each other to avoid intermodulation interference.

    (6) do not pat the sound-absorbing head of the microphones with force in order to avoid damaging the microphones head.
