A quick solution to running the balanced TRS output of a sample pad into the XLR input of a stage box (some venues take TRS, others only XLR) is to pop this on a TRS-to-TRS cable. Best is always to have cables with the exact connectors, but with the adapter you may need to carry fewer cables (or at least fewer long ones).
The shell is connected to ground which may be a downside in some situations.
The red latch on the TRS female side is quite hard to open but taking out the spring inside eliminates that.
Compared to alternative solutions
This adapter probably puts less strain on the socket than using an XLR female to TRS male adaptor on an XLR cable and it's better to avoid having adaptors stick out of a pad that gets beaten and may wobble.
A convertible unisex XLR connector is slightly shorter than this adapter if you're happy to solder it onto a cable with a TRS connector on the other end and is also cheaper than this adapter and its female XLR version together.
Note
Be careful with output levels, as line level might be too hot for a mic-level input.
