Best audio input on the Sony FX3

Which audio input on the Sony FX3 gives the best quality?

When shooting with the Sony Fx3 we have multiple audio input options to work with. On the top audio handle there’s two XLR inputs with a full set of controls as well as a 3.5mm input with a level control. If not using the audio handle there’s a 3.5mm input on the side of the camera body with levels controlled in. cameras menu or you can also connect a microphone or wireless system to the MI (Multi Interface) Shoe on the camera where the levels are controlled within the external device.

Comparing the FX3 Inputs

In an effort to have a better understanding of how all these input options compare I decided to do a controlled test. I created an audio sample using a high quality voiceover from BigFish Media along with a music track from Artlist. This audio was sent via my Sony UWP D-26 Wireless System so that each input would receive exactly the same signal and then compared the results to see which one provides the most accurate recording with the lowest noise floor.
