The U3 system can be used to connect microphones to DSLR cameras-provided you have an adapter to run between the XLR receiver and the camera's (usually 3.5 mm) audio input.
Remember to use the U3C when connecting condenser microphones. The basic application is to run wirelessly from a dynamic microphone to a soundboard-live, at home or in the studio.But there's a lot more you can do with the U3 System. The U3 system is not only great for singers and rappers. Wireless freedom is liberating for harmonica players, public speakers, DJs, preachers, auctioneers, actors, politicians.
