How to find out the cause of malfunction of wireless system?

Issue Time:2020-06-09
This week I want to talk to you about how to find out the problem when your wireless microphone system is malfunctioning.

Sometimes we find that the wireless system is damaged, but how do we determine where the problem is? Today, I want to share the three most common questions and tell you how to find out why.
1. I did buy the available frequency range in my area, but it still has interference. 
If you are sure that the frequency is available, maybe the problem is the busy frequency.  We know that in one area,   the frequency is available for everybody. if other people use this frequency at the same time, interference is produced. In this case, you can use the auto-scan function for free frequency.
2. one Microphone is not working, what should I do?
We need to judge that the problem is in capsule or body.  we need a good microphone and make some marks on two microphones (for example the good mic is capsule2+body2, the bad mic is capsule1+body1). And then swap two microphone capsules. if the capsule 1 + body2 is not working,  and capsule2+body1works, the problem is capsule 1. 
3. One channel is not working , what should I do?
if you find that one channel is not working , you can swap two microphones, and connect the channels. For example, Channel 1 is not working, you use Mic2  to connect channel 1.  if they can work, the problem is the Mic1. and we can judge the capsule and body by step 2.
I prepare an operation video for further understanding.
