The Stereo Windshield AG Kit from Rycote is suitable for a pair of microphones, each 19 to 25mm in diameter and 190mm in length. It includes a Stereo Suspension with Back-to-Back Clips, a Stereo Windshield and a Stereo Windjammer.
The Stereo Suspension includes a pair of their patented Lyre shockmounts on a riser to cradle the first mic, front and back. Then, the Universal Back-to-Back clips fasten the second microphone to the first. The hardware is boompole mountable. The Stereo Windshield attenuates up to 30dB of wind noise, while giving almost no signal attenuation.
The Rycote AG Stereo Windjammer offers an additional 20dB of wind-noise reduction over the windshield. It's tightened with a drawstring and toggle to allow snug and easy fit.
