What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
It joins a male XLR cable end to a male RCA cable end. It will not plug into a jack on its own.
Detail 02
RCA is unbalanced, so the XLR's noise-cancelling advantage is lost past this point. Keep the cable run short.
Detail 03
No isolation and no level conversion. Ground hum between two pieces of gear passes straight through.
Detail 04
A microphone's output is far too quiet for an RCA line input. This adapter cannot make up that gain.
Detail 05
Standard plating, fine for typical indoor use. Less corrosion resistance than gold on connections left in place.

Product questions
Straight answers to the questions shoppers most often ask about this product.
Not usefully. Mic level is far below line level, so you would get a very quiet signal. You need a preamp or a mixer between them.
It connects them, but passively. There is no transformer, so you lose balanced noise rejection and get no ground isolation.
Either way electrically. In practice it is used to take an XLR output into an RCA input. Match your source and destination levels.
Unbalanced connections between separately powered gear commonly create a ground loop. A transformer isolator or a shared power outlet usually fixes it.
