UR3 – UHF-R Microphone Plug-on Transmitter
The UR3 enables broadcasters to simply plug any microphone on a small wireless transmitter. In addition to including UHF-R wireless technology, the discrete transmitter provides special features to make broadcasting applications hassle free: RF mute switch, exchangeable coloured cups for easy visual differentiation and full range of phantom powerThis must be provided to all condenser microphones in order for them to operate.
