Studio microphone RØDE NT-SF1 — wired condenser, 20–20000 Hz, sensitivity −30.4 dB, 63 Ω output, brass housing, black

The RØDE NT-SF1 is a wired condenser studio microphone engineered for accurate multichannel capture and studio recording. Its frequency response spans 20–20,000 Hz with a sensitivity of −30.4 dB and an output impedance of 63 Ω. Housed in solid brass with a black finish, the microphone is powered by 48 V DC and draws approximately 6.2 mA. The NT-SF1 is built to capture full spherical sound fields and is suitable for professional recording environments where precise spatial audio is required.

Advantages

The NT-SF1 uses multiple precision condenser capsules arranged to capture a complete 360° sound field, allowing post-production manipulation of directionality and spatial position when converted from A-Format to B-Format. Its solid brass construction provides mechanical stability and durable protection for sensitive internal components. With wide frequency coverage and low inherent noise, the microphone supports clear capture of voices and instruments. The wired connection and standard 48 V phantom power make it compatible with common professional audio interfaces and mixing consoles.

Suitable for

• Multichannel and surround sound recording for film and broadcast
• Location and field recording where spherical capture is needed
• Studio sessions for voice and acoustic instruments
• Virtual reality (360°) audio production and immersive projects

Key specifications

How to use

Install the NT-SF1 using an appropriate mount or supplied suspension shockmount and position it to encompass the sound source or environment you intend to capture. Connect the microphone to a compatible preamp or audio interface that provides 48 V phantom power. Record in the microphone’s native A-Format and convert to B-Format in your DAW or using dedicated conversion tools and plugins to adjust directivity, rotation and spatial position during post-production. Monitor levels to avoid clipping and use wind protection when recording outdoors.

Recommendations

For best results in multichannel workflows, record at a sample rate and bit depth consistent with your project requirements and use the manufacturer’s SoundField plugin to convert and manipulate A-Format to B-Format. Employ the included windshield and furry cover for outdoor recordings and the suspension mount to reduce handling noise in studio or location work.
