Precautions for the use of microphones in conference room audio equipment.Music bar sound price

　　Do you know the precautions for the use of microphones in conference room audio equipment? Now there are more and more opportunities for people to use microphones, but not many people can really use them well. Let's talk about a few common misunderstandings that we pay special attention to in use.

　　1 Do not tap the microphone and blow into the microphone during the auditionsolar power system

　　Because the pickup part of the microphone is relatively precise and the components are very delicate, tapping the microphone or blowing air to the microphone head can easily cause damage or displacement of the components, which will ultimately affect the sound quality.

　　2 The microphone is too far and too close to the sound source

　　The best distance for microphone pickup is about 10cm. Some "leaders" speak far away from the microphone, and some singers are close to the microphone. Too far away will cause the pickup sound to be too low. At this time, if the volume is pushed up, it is easy to cause howling; Picked up, making a "pu-pu-pu" interference sound.

　　3 Hold the microphone antenna

　　When using the wireless microphone, it is forbidden to hold the antenna transmitter at the bottom of the microphone. Since the wireless microphone belongs to the transmitter, the antenna is generally located at the bottom of the microphone. Holding the bottom of the microphone will cause the transmitted signal to be shielded and attenuated greatly, which will easily cause the microphone sound to be unstable. even off-frequency.

　　4 Do not turn off the microphone switch

　　When talking in a meeting or after singing, you should turn off the microphone switch in time. At this time, the volume fader of the mixer is not turned off in time: on the one hand, other noises are also picked up, and on the other hand, some unnecessary speech sounds are played. Come out and cause embarrassment.https://www.bropool.com/hot_tub/

　　5 Use the mouth against the microphone

　　Some people do not pay attention to or pursue a near-talk effect when using it. Often the mouth is attached to the microphone, which not only destroys the normal frequency response of the microphone, but also poses a great hidden danger to health. There are many germs on the microphone grille.

　　6 When the microphone is not used for a long time, do not remove the battery

　　Nowadays, most wireless microphone transmitters require battery power. When the microphone is not in use, the battery should be withdrawn to avoid battery leakage and corrosion of the microphone.

　　7 Wireless microphones should replace the battery in time

　　During the use of the wireless microphone, the low battery power will affect the instability of the transmitter's transmitted signal. If the battery is not replaced or fully charged in time, cross-frequency is prone to occur and noise is generated in the case of large environmental interference.

　　8 condenser microphones, phantom voltage must be applied

　　Since the capacitor of a condenser microphone needs to be polarized to work properly, a phantom voltage must be applied when using a condenser microphone. Be sure to turn on the phantom power switch on the mixer or mixer, and pay attention to the voltage value and polarity, otherwise, it may not be used normally and may cause damage.
