Shure WA310 is an XLR female-to-TA4F adapter cable, to allow plugging a dynamic microphone into a Shure bodypack transmitter.
The TA4F on WA310 goes straight to the input of a Shure bodypack transmitter, including SLX1, QLXD1, ULXD1, UR1.
The female XLR can plug into anything you want, but typically it would be used for a dynamic microphone - perhaps your favourite handheld being used for an on-camera interview.
