Many people in the use of wireless microphone due to various misoperation, so that the microphone produces a variety of whistling, sonic boom and other harsh sounds, this situation should have been experienced by everyone. Don't look at the microphone is so simple to use, to avoid this embarrassing situation during use, you need some small tips:

Do not hold the microphone in your hand

Because most microphones are pick-up directed, such as grasping the microphone head (grille) part with your hand, this will change the directivity and frequency response of the microphone, and will also produce harsh sounds such as whistling due to the aggregation effect of the palm.

Do not hold the antenna firing part of the microphone in your hand

Traditional handheld microphones, transmitter circuits and antennas are located on the bottom of the microphone. When the user's hand touches the antenna part, most of the RF energy will be lost due to the inability to enter the air, which further reduces the reception range of the wireless microphone and affects the reception effect.

Keep the microphone away from your mouth

When using a handheld wireless microphone, the distance between the microphone microphone and the mouth is usually maintained at 5~10cm, too close will produce a close-up speaking effect, too far away will lead to too small sound, in both cases will affect the sound quality effect;

When using lavalier wheat, avoid the head of the microphone too far from the mouth, and keep it as close to the mouth as possible;

When using the head-mounted microphone, pay attention to avoiding the microphone microphone head in front of the mouth, so as to avoid the impact of air flow on the microphone head when opening, and it is better to adjust the microphone head to the position on both sides of the mouth.

Avoid facing the microphone directly against the speaker

If the microphone is directly facing the speaker, it will put the whole system in a closed loop, so that there will be a whistling situation, which is to be avoided.

Avoid two wireless microphone transmitters coming too close

When it is necessary to use a plurality of wireless microphone systems, and if the two microphones are using the same series of products, then it is recommended to add an antenna splitter to minimize the mutual interference between the antennas, if the antenna does not have a distributor, the antenna of the wireless microphone receiver should be adjusted to the optimal position, and they are arranged in a row, so that the wireless receiver maintains a certain distance (the antennas on each receiver can not contact each other), so that each receiver has good reception conditions, This enhances the directivity of the wireless receiver. In order to obtain a good wireless signal, mutual interference between frequencies is avoided.

If it is used in large performances, it is best to install an extended or active amplification antenna to improve the reception effect.

・Prevent the occurrence of mute during the performance

Do not turn off the power and mute switches during the performance. The power and dumb switches can be bonded with a black cloth, so that the wireless microphone transmitter is always in working condition, and the volume and switch can be controlled by the tuner.

If you encounter the need to use two handheld wireless microphones of the same model at the same time, in order to avoid misoperation, each wireless microphone should be labeled with a different color label for easy identification, and generally the bottom of the handheld wireless microphone should be labeled. At the same time, a logo or marker of the same color as the microphone should be pasted on the channel corresponding to the microphone on the mixer. In this way, even if the person performing on stage takes the wrong microphone, the staff can correct it in time.
