As other types of music wireless devices, the wireless microphone can give us more flexibility using in for long distance as well as getting rid of some troubles with the lines. However, there are still several common problems that you might often encounter when using it because of some reasons. Of course, if you are not a person who has time and want to do it yourself, electronic fixing stores would be so happy to have you as their customer, but the fee would be out of your control with just a small problem. You don’t want that to happen, right?
With some of my experiences in using and repairing wireless microphones myself, it thinks this post will help you a lot in troubleshooting problems and fix them as soon as possible without having to rely on a paid service. However, I can only run into some common problems with wireless devices, but these basic things can be useful.
Check For The Static
Sometimes static appears on the wireless microphone when it is on. In fact, it is not only the problem of the wireless microphone but also other types of audio devices such as record player, Bluetooth headphones, and mp3 player. Indicating the causes of this problem is what you need to do first to have some exact adjustments.
The most common cause of static on a wireless device is because of the distance. The microphone might be too far from its receiver so the transmission can be interrupted. Another thing might be the battery. If the batteries are dying, the signal might be weakened and easier to interfere. If the problems are from one of these causes, you know what to do, right? First of all, change the batteries and open the microphone again. After that, try to stay close to the receiver to recover the signal line when using the wireless device.
If you are using the wireless microphone for on – stage performances, the best way to get a good signal is bring it to a higher place and near the microphone. Normally, the receiver is put onstage or backstage. Moreover, make sure nothing blocks the transmitting line between the receiver and the microphone. If you have some experiences about staging and stage equipment, it won’t be a problem.
Adjusting The Frequency
So as to avoid interference, you have to make sure that the frequency of the microphone and the receiver are similar. Another thing which might be a problem is that those frequencies can be the same as other wireless devices. The best way is to change them to a frequency that is completely free. If you meet some interference, you might want to change your current frequency up or down at least 2MHz so as to make sure they don’t meet each other in the same bandwidth anymore. A certain area will have some selections for the wireless microphones so don’t worry if you can’t find one that is suitable for you from the beginning.
Another solution for the frequency interference is a device called wireless frequency analyzer. It can completely solve your problem anywhere in no time, but the price is not cheap at all, so you should consider carefully before investing money on it.
Another common issue I want to talk about is the latency. With digital microphones, the bandwidth used must be at least ten times broader than a normal one, that the reason why in some low-quality devices, the latency is too high. It means that when a person speaks, it takes quite a lot of time for the signal to be transmitted to the receiver thus produce the sounds from the loudspeakers.
The main reason is because of the signal type of the digital microphone. The analog signals must be transformed into a digital one and then transform back into analog to make sounds. Those conversions not only make some certain losses in sound quality but also slower the speed of the signal. Therefore, try to make the choice wisely by testing several times before purchasing any product. it can be cheap and attractive, but with high latency, it can affect badly to your speech as well as annoy the audience. Most of the manufacturers have fixed these problems but you still have to take a look at the technical information of the wireless microphone to make sure everything is alright.
Channels Changing Suddenly
Sometimes the wireless microphone can change the channels automatically because of some synching via infrared. This doesn’t happen a lot, but it’s going to be very annoying and frustrating because it might cause some changes in settings and some interference as well. This problem is quite easy to fix but only if you know how.
First of all, you have to make sure all the receiver is working properly and you will be able to find the one your microphone is shifting to. The main purpose of this method is to remove the wrong receiver and put your device in the right place first, then try to get rid of negative syncing in the future. To do this, there is nothing better than using dark tape to cover the infrared signal. It will stay with the right receiver after doing so. If you want to make any changes, you just need to remove the tape and setting things up the way you want.
On a whole, using wireless microphones can bring you so many advantages, especially when you are on stage and don’t want to get in some troubles with those lines and limit your activity when performing. Of course, you still have to be aware of some common problems with a wireless digital device if you make use of it such as static, latency or channel shifting, but don’t worry because they can be fixed immediately and don’t affect your performance. But above all, the thing you have to care about first is the quality of your wireless microphone. If you purchase the best one from the beginning, you will have to encounter fewer problems and have better uses.
