The Saramonic C-XLR+ is a useful audio adapter that lets you easily connect microphones and audio sources that have 3.5mm male jacks into the XLR inputs on professional video and cinema cameras, audio recorders, mixers, and more. It’s compatible with active, battery-powered microphones and passive microphones, such as the lavalier mics that come with wireless systems. If you engage phantom power on the camera or other device, a built-in converter in the C-XLR+ changes the current from +48-volts to the 3 to 5-volt current that plug-in-powered and some passive 3.5mm microphones require. This happens automatically. There are no controls on the C-XLR+ that need your attention.
