The wireless microphone in the conference room audio equipment is converted from sound to signal, and then modulated into high-frequency radio waves to be emitted, and then received back to demodulate, amplify, and restore to sound. There are many links in the whole process. Note that it may still work, but its stability and working range will be reduced a little bit, and if one more link is not noticed, it will be reduced a little bit, and the scope of use will be narrowed a little bit. The wireless microphone is either disturbed or "running frequency", and it cannot be used normally even at a very close distance. On the contrary, all links have noticed that the anti-interference ability of wireless microphones will be greatly enhanced, and the stability will be greatly improved.
1. Problems that operators should pay attention to when using
1. Matters needing attention before use
The operator should carefully check the wireless microphone before performance or use, connect the system correctly, set up the antenna reasonably, and ensure that the microphone is in a normal working state, mainly pay attention to the following points. To avoid the phenomenon of no sound from the wireless microphone during performance or use
(1) Check whether the battery box is in good contact and whether the battery is charged.
(2) When starting up, the receiver should be turned on first, and the RF meter should be checked to make sure that there is no RF interference in this channel, and then turn on the transmitter.
(3) Check the microphone mute switch to ensure that the wireless transmitter and microphone are always in working condition.
(4) Do not stack receivers together to avoid mutual interference between receivers.
(5) Take out the power supply after use, because some microphones are in the standby state because of the light touch switch, or the battery will be used up when working with electricity.
2. Problems that should be paid attention to in use
(1) During the performance, pay attention to observe whether the RF signal indicator is normal to prevent interference from external wireless signals.
(2) When the microphone is handed over, avoid stacking multiple open wireless microphones together, and do not get close to the receiving antenna, so as to avoid intermodulation interference and affect the use of wireless microphones.
(3) If there is noise in the sound, it may be that the microphone head is not installed in place, or the sensitivity setting of the microphone head is too high, or the frequency point used may be interfered, mainly due to the following reasons.
①There are interference sources (such as mobile phones, walkie-talkies, cordless phones, etc.) in the venue. In this case, change the frequency of the receiver first, find the frequency where the RF signal light of the receiver has no interference, and perform frequency matching; When using a set of wireless microphones, special attention should be paid to opening the frequency band.
②The poor reception conditions of the venue (such as there are pillars blocking the venue, or the reflection of metal equipment and glass in the venue, the sound control room is far away from the venue and there is a wall blocking or turning, etc.), which will affect the normal reception of the signal. The problem can usually be solved in the following ways.
① Try to use a diversity wireless system (ie, one microphone, two antennas), because the receiving range of the two antennas is large.
②You can change the direction and angle of the antenna to improve the reception effect.
③If the receiving environment is too bad, such as the sound control room is not in the venue, just extend the antenna to solve the problem
④ When it is necessary to replace the battery of the wireless microphone in use, the power of the microphone should be turned off first, then replaced, and then the microphone switch should be turned on.
⑤ Note that there is a power selection in the wireless microphone handle, L gear is low power transmission, H gear is high power transmission (the transmission and reception distance can be long and the power consumption is too large), which is set according to the use environment.
