The Rode NT-SF1 is a compact, high-precision condenser microphone designed for 360° audio capture in Ambisonics A format. Its four-channel design captures a full-sphere sound image, making it ideal for immersive applications ranging from VR productions to spatial audio experiments. The "SF" designation honours SoundField, the company behind the first commercial Ambisonic microphone (1978). Now part of Rode's parent company (the Freedman Group, since 2016), the NT-SF1 makes professional Ambisonics accessible, merging SoundField's legacy with Rode's practical engineering. Combining decades of acoustic innovation with modern cost-efficient design, it delivers broadcast-ready 3D audio capture - equally suited to studio and field recording workflows.
the Rode NT-SF1 features four phase-matched 0.5" TF-45C cardioid capsules are arranged in an optimised tetrahedral configuration, delivering exceptional spatial accuracy across a 20Hz-20kHz frequency range. With a robust maximum SPL handling of 129dB and low self-noise (15dBA per capsule), the NT-SF1 maintains clarity even in demanding recording environments. The proprietary JFET impedance converter and bipolar output buffer ensure signal integrity with a consistent 63-ohm output for stable long-cable runs. Complete with a custom 3m breakout cable, threaded stand adapter, and both foam and faux-fur windshields, it is field-ready for any scenario.
Engineered for VR sound designers, film audio professionals, and spatial audio pioneers, the NT-SF1 combines practical durability with technical sophistication. The solid brass body features a scratch-resistant ceramic coating, while its compact 286g form factor enables flexible placement. Rode's free SoundField plugin (VST/AAX/AU) transforms the four-channel capture into versatile formats - from binaural to 7.1.4 surround. Real-time spatial processing allows for intuitive soundfield orientation adjustments, while advanced decoding preserves phase coherence for critical applications. Whether capturing environmental ambisonics or creating interactive VR audio landscapes, the NT-SF1 delivers professional results with high workflow efficiency.
Founded in Sydney, Australia in 1990, Rode is a specialist in high-quality studio microphones. With its very first in-house, completely Australian-built model, the NT2 large-diaphragm microphone, the company created a classic which is still produced in its current and enhanced version, the NT2-A. An extensive range of studio and live microphones has also been added, regularly updated, and expanded over the years. These new additions include a variety of professional microphones which are designed for video and mobile applications and can be connected directly to SLR cameras or smartphones.
The NT-SF1 combines simple setup with advanced capabilities. The included accessories support everything from studio mounting to handheld field recording, while the colour-coded XLR outputs simplify multi-channel routing. For optimum results, equal gain across all four channels must be maintained when recording. The SoundField plugin then provides comprehensive post-production control, including dynamic soundfield rotation, real-time format conversion from stereo to 7.1.4 surround, head-tracking integration for VR workflows, and beamforming for focused spatial capture. With a plugin latency of 882 samples, the NT-SF1 brings broadcast-ready Ambisonic capture within reach of content creators at all levels.
