It enables you to put the recorder into a standard microphone clip, just as if the recorder were a microphone. This lets you use any microphone stand to hold the recorder; depending on the versatility of the mic stand, you can position the recorder just about anywhere you want on a performance stage.
Okay, I get it now! I thought I had to try to unscrew the bottom of the small tapered end to reveal some female threads but now I know that the tapered portion is similar to a microphone and slides into a mic holder. It is not shown being used so I had to try to understand without any description. Thanks!
