1. Simply connect the negative electrode of the 9V battery with the battery housing, so that the transmitting antenna of the wireless microphone can be extended through the battery housing, and the transmitting distance can be increased to prevent segment frequency and running frequency.
2, the negative end of the wireless microphone 9V battery holder is connected with a enamelled wire wound into a tight spiral, fixed on the opposite side of the wireless microphone tail tongue plate, the V section is longer (in the diameter of 2.5MM around the head and then back to the starting point), the U section is shorter (in the diameter of 4MM around the head and pressed).
3, have the ability to disassemble the wireless microphone. The tail out of more than two inches, exposing more than half an inch circuit board, find the location of the transmitter tube, in the 1P capacitor (or a few P capacitors and the smallest capacitor) welding a enamelled wire wound into a dense spiral, fixed in the wireless microphone tail slot, the outer diameter of the spiral is about less than the width of the slot, flattened fixed in the slot. Note: The use of No. 5 battery wireless microphone is not suitable for this, because the use of No. 5 battery wireless microphone already uses the battery housing.
Reasons and Solutions:
1 There may be a problem with the signal receiver or transmitter of the wireless microphone, resulting in unstable signals and frequent disconnection.
2 You can check whether there is interference from other electronic devices, and you can also try to replace the microphone or receiver.
3 If the problem is still unresolved, consider using a wired microphone or switching to a more stable wireless system. In addition, you can conduct sufficient drills in advance to test whether the equipment is reliable to avoid accidents during important performances.
