First, check our compatibility list to make sure that your Canon camera is compatible with our microphone
If it is compatible, please note that Nikon DSLR cameras have a stereo (TRS) external microphone port, so the microphone needs to be plugged into the port using the TRRS to TRS (4 to 3 pin) adapter that comes with our microphone package.
P.S: Ensure that the microphone jack is properly plugged into the female end of the TRRS to TRS adapter by pushing the jack in all the way till you hear a “click” sound. If there’s no proper contact between the mic and adapter, the combo will not work.
Check images below to see what the adapter looks like and for a better understanding of what we are describing.
Again, you don't need to purchase the adapter separately, it comes with the PowerDeWise Professional Lavalier Microphone package.
Though unlikely, but if after trying all the steps above, the microphone doesn’t still work for your Nikon DSLR camera, please contact our customer support team.
