From the RØDE Microphones Vimeo Channel:
RØDE is pleased to announce the RØDELink fully digital wireless audio system. Using a next-generation 2.4GHz, 128-bit encrypted digital transmission sent on two channels simultaneously, RØDELink provides a high-resolution 24-bit/44.1k digital audio signal at a range of up to 100 meters (over 100 yards).
The first product offering in the RØDELink system is the Filmmaker kit, which includes a camera-mounted receiver, beltpack transmitter and broadcast-grade lavalier microphone.
B&H has the RodeLink Wireless Filmmaker Kit available for preorder for only $399.00 with free shipping (competing products in that market segment cost about 50% more).
