The microphone comprises two components: a transmitter and a receiver. They communicate wirelessly with each other using Bluetooth technology and feature a range of up to 100', depending on conditions. With the receiver attached to your camera it is still possible to capture additional audio using the camera's built-in microphone. In addition, audio picked up by the camera can be relayed back to the transmitter. The transmitter features a headphone jack that allows the camera operator to communicate with the person wearing the transmitter by speaking into the camera's microphone. There is also a headphone jack on the receiver so that the camera operator can monitor audio even if the camera itself doesn't provide a headphone out of its own. Finally, the transmitter features a 3.5mm mic input allowing you to use a third-party microphone rather than the built-in one. The transmitter can either clip on your belt, or be worn using the included elastic arm band Includes windscreen to help reduce wind noise when filming outdoors Includes two earphones for monitoring audio and a pouch to store everything in For Sony cameras and camcorders with Multi-Interface Shoe Transmitter powers from a single AAA battery; receiver power directly from the camera Corresponds to "5.1-channel Center Mic" mode
