The Microphone Arm attaches to your Microphone Arm Clamp and holds your Microphone in place. It’s extremely important that you watch all the training videos for placing & using your Microphone. One of the most common mistakes people make is to place the Microphone too far away, or angle it up towards the ceiling instead of at the subject’s mouth. Great videos require great audio, and so you need that Microphone as close to your subject as possible.
