Nordic Audio Labs NU-24K – Large-Diaphragm Cardioid Condenser Microphone with FloFET™ Technology

OVERVIEW

The NU-24K is a large-diaphragm cardioid condenser microphone featuring FloFET™, Nordic Audio Labs’ proprietary next-generation circuit technology, developed entirely in-house with the D100K capsule.

FloFET™ is designed to optimise the interaction between the circuit and capsule, preserving transient detail and dynamic expression while delivering a controlled low-frequency response with weight and authority. Its transformerless design combines clarity, accuracy and reliability with effortless musicality.

The D100K capsule minimises unwanted resonances associated with conventional large-diaphragm condenser microphones, delivering exceptional transient response, smooth high-frequency extension, consistent off-axis performance and a natural sense of depth.

Together, FloFET™ and the D100K capsule give the NU-24K a natural, detailed and controlled sound with exceptional transparency and effortless clarity

 

KEY HIGHLIGHTS

Signature NU Sound – Lush, Smooth, and Realistic:

Powered by Nordic Audio Labs’ proprietary FloFET™ circuitry, the NU-24K offers the flattering warmth of a tube microphone with the accuracy of a solid-state design, giving you a truly unique tonal signature that works across all genres and voice types.

D100K Precision Capsule for Exceptional Detail:

At its heart is the 30mm D100K edge-terminated capsule, delivering lifelike transients, ultra-smooth top-end, and an off-axis response that ensures recordings remain natural and phase-coherent, even in less-than-ideal environments.

Handles Any Voice – And Everything Else:

Whether you’re tracking vocals, instruments, or field recordings, the NU-24K shines. It’s voiced to sound great on anyone, and delivers top-tier tone on virtually any source – ideal as a desert-island mic for any serious studio.

Performs Beautifully with Any Preamp:

Thanks to its low output impedance and high output level, the NU-24K pairs well with all types of preamps, including those found in budget audio interfaces – making pro-level sound accessible to all.

Humidity Resistant for Long-Term Reliability:

Unlike many condensers, the NU-24K’s capsule design resists humidity, helping avoid moisture-related issues during vocal sessions or on-location recording.

Quiet and Clean – Even on Quiet Sources:

With a self-noise of just 17.6 dB(A) and impressive SPL handling up to 136 dB(A), the NU-24K is equally at home recording soft acoustic passages or powerful performances without distortion or compromise.

Handcrafted in Finland – Built to Last:

Lovingly handmade and backed by a 10-year warranty, the NU-24K reflects Nordic Audio Labs’ dedication to craftsmanship and long-lasting studio excellence.

FEATURES

• Proprietary D100K resonance-minimised capsule, engineered to reduce low and low-mid frequency energy while preserving classic large-diaphragm character and a natural top-end lift
• Superior clarity, detail and support even when recording from greater distances, for a large and natural sound
• Smooth, excellent transient response often associated with ribbon microphones, without inheriting their fragility or harsh resonance peaks
• Minimised capsule resonance means EQ, compression and other processing reveal fewer microphone-induced artefacts
• High-impedance components moved into the capsule for a shorter signal path, preserving signal integrity and adding built-in humidity protection
• FloFET™ circuitry: a transformerless design that lets the microphone breathe, delivering the weight and authority of a transformer mic with the clarity of solid-state and the character of a tube — without the drawbacks of either
• Handmade with love in Finland
• 10-Year warranty
