Wireless Lavalier Microphone to XLR Wireless Transmitter Adapter

I started thinking about different forms and finally found this stuck in the ring when I was playing around with the XLR interface. You need to use NEUTRIK or Jiasound XLR connectors in the design. Maybe others can also work, you can tell me in the comments.

Materials:

XLR female Connector

3.5mm male Connector

Two-core audio cable (23cm)

3D printing part

Electrician adhesive cloth

Tools:

Soldering iron

How to solder? Because it is balanced to unbalanced, in my many tests, I found that if there is no XLR microphone connection, there may be current noise, but after I made it more carefully, I grounded the XLR shell and it seemed that there was no This kind of electric current sounds. The audio cable here is 21CM, which is a bit short and can be extended to 23CM.

Solder the XLR connector first then do the 3.5mm. In the XLR connector is different with the normal soldering method. Do exactly what is show in the image, You will be able to Solder it right.

Before you put all the component, must test the cable. In case some of part in shorted or miss soldered. Plug-in to you mic and test it. Working or not? did have current sound?

Put the 3D prints on the XLR connector, in the position where the ring is. Then put back the cover.

Connect with your wireless microphone for the final test. Ensure that the connection is accurate, twist the wire, and there is no problem with the audio.
