RØDE NT-SF1 Microphone

A-Format™ is the raw, four-channel output captured by the microphone's individual capsules. This format is essential because it allows you to manipulate the sound field in post-production, giving you the flexibility to convert the recording into various surround sound or spatial audio formats later.

Yes, you will need to use the included RØDE SoundField processing plug-in to convert your A-Format recordings into B-Format or other surround sound standards. The plug-in is designed to seamlessly integrate with most major digital audio workstations.

While the NT-SF1 is specifically engineered for 360° immersive audio, you can certainly use it for stereo applications. By using the processing software, you can manipulate the virtual microphone patterns to create a stereo image, though it is primarily intended for more complex spatial projects.

The NT-SF1 requires 48V phantom power to operate. Because it features four individual capsules, you must ensure your audio interface or recorder can provide stable 48V phantom power across all four input channels simultaneously.

Yes, it is well-suited for field work, especially since the kit includes a blimp-style windshield and a furry wind cover to manage wind noise. However, because it is a sensitive condenser microphone, you should handle it with care in extreme weather conditions.

The microphone uses a multi-pin output that connects to the included breakout cable, which splits the signal into four standard XLR connectors. You will need an audio interface or field recorder with at least four high-quality XLR inputs to capture the full ambisonic signal.
