The Rode Link Wireless Filmmaker Kit is designed by understanding the audio recording requirement on-location. This kit includes an RX-CAM wireless receiver, a TX-BELT wireless transmitter, and a lavalier microphone. The transmitter and receiver utilize the Series II 2.4 GHz digital transmission to provide a 128-bit encrypted working signal range of 328 feet. The one-touch pairing procedure makes set-up an easy work. Both transmitter and receiver have an OLED display that shows mute status, input level, and battery status. The receiver can be mounted to the camera with its removable shoe. You can charge the AA battery-powered transmitter and receiver via their micro-USB port. The omnidirectional lavalier microphone offers a maximum SPL of 110 dB to ensure clean sound quality. Its pressure gradient acoustic principle provides high responsiveness to the incident sound.
