This is a complete, genuine SHURE, wireless set...the body pack can be used with the included headset microphone, or with an instrument such as a guitar. (the body pack DOES NOT have a belt clip)
The transmitter runs off of a single 9v battery (not included) and has a 1/4" TS input
The receiver has an extendable antenna, a standard 12v DC barrel input for power, and a 1/4" TS output. (I will include a US or EU power adapter, just let me know which you need.)
This item is fairly old.
It operates on the 186.200mhz frequency, so make sure that works in your country.
let me know if you have any questions.
