For a wireless microphone, it encounters a dead angle during use (that is, sometimes it does not receive a signal in a certain place in a field, sometimes with a handheld microphone, the person does not move, but the body is slightly shaken, and the signal may sometimes be absent). This kind of thing is really nerve-wracking. For the average user, it is always thought that the quality of the wireless microphone is not good. In fact, there are several reasons for this:
First, there are some sources of interference in some places. Nowadays, communication tools are developed and diverse, such as mobile phones, walkie-talkies, cordless phones, etc., all of which interfere with each other, and there are metal equipment and glass reflections in the field. This happens.
Second, some venues have poor reception conditions - if there is a column blocking in the field, and the sound control room is far away from the venue, there is a wall blocking or turning a corner, etc., which will affect the normal reception of the signal.
How to solve this situation? The following empirical summaries are for your reference:
1. Some can try a different frequency, because some sources of interference may just conflict with the frequency of this set of microphones. Changing a set of frequencies can often solve the problem. If there is a receiving environment such as a column in the field, it is not good to buy a single-shot and dual-receiver (ie one microphone, two antennas), such as SHURE's EUT24/58, because the two antennas have a larger receiving range, such as people. While walking, the two yellow lights of the receiver are illuminated, indicating that they are in all directions; if the yellow light on the left is bright, the receiving antenna on the left is within the range of your left speech. Once you get out of the receiving range on the left, enter On the right side, the yellow light on the right is lit immediately, and the antenna on the right works immediately. This will ensure that your speech is received in all directions.
2, sometimes you can change the direction, angle, etc. of the antenna, can improve your receiving conditions.
3. If the receiving environment is too bad, you can use multi-frequency adjustable wireless microphones, such as SHUREUC, UD4 and so on. The US SHURE company recently introduced two multi-frequency adjustable wireless microphones ULXS standard version and ULXP professional version, which is different from the previous frequency selection method. It automatically scans the frequency around the interference and eliminates it. The rest is the available interference-free frequency, and 20 sets can be used at the same time.
4. If the receiving conditions are more demanding, such as the sound control room is not in the venue, or there are pillars, wall barriers, etc., after our test, as long as the antenna can be extended to solve the problem, the emergency method is as follows: Take a video cable, About 10~15 meters, the original receiver antenna is removed (or one of the self-purchased antennas) is connected to the video cable, and then the antenna is installed where you can test and receive the signal. Of course, this needs to solve the process problem, the cable line should go as dark as possible, if it is clear, it should be neat and standardized, and the antenna should be better to look good, which does not affect the reception and is beautiful and firm.
