The Rode SoundField NT-SF1 is an ambisonic microphone designed to provide clear and accurate reproduction of 360° sound for recordists in VR, film production, and audio for video games. It features four 1/2" TF45C cardioid condenser capsules arranged in a tetrahedral array, wired to an XLR 10-pin connector for four-channel, A-format output.
