This is the RODE Link Filmmaker Kit. I used it for shooting with a single-lens reflex camera. To prevent disconnection, electrical tape is wrapped around the microphone connector on the transmitter. RØDELink offers a range of digital wireless systems. Using Series II 2.4GHz digital transmission and 128-bit encryption, it constantly monitors and hops between frequencies to maintain the strongest possible signal level, with a range of up to 100 meters (over 100 yards). The RØDELink Filmmaker Kit includes everything you need to start wireless video shooting, such as a receiver, transmitter, and a broadcast-quality lavalier microphone. The receiver (RX-CAM) features an OLED display that shows information such as level, battery status (receiver and transmitter), mute, and channel selection. The unit can be mounted on a standard camera shoe mount, a 3/8-inch screw, or a belt clip, and the shoe mount can be positioned in one of two locations for added versatility. The lightweight transmitter (TX-BELT), which can be attached to a belt or clothing, uses a locking screw to ensure a secure connection with the microphone. RØDE includes an omnidirectional lavalier microphone in the kit to achieve the best audio reproduction quality.
