Soyuz 013FET-M Matched Pair Small Diaphragm FET Microphones

Matched Pair Small Diaphragm FET Microphones for Stereo Recording

The Soyuz 013FET-M is a factory-matched pair of small-diaphragm FET condenser microphones designed for professional stereo recording in studio, stage, and broadcast environments. Featuring detachable cardioid capsules and integrated -10 dB pads, this matched pair delivers consistent frequency response, accurate stereo imaging, and detailed transient capture. Whether used for drum overheads, piano, orchestral ensembles, choir recordings, or acoustic instruments, the 013 FET-M provides balanced, dimensional sound in a reliable stereo configuration.

Factory Matched Capsules for Accurate Stereo Imaging

Each microphone in the 013FET-M set is carefully matched for sensitivity and frequency consistency to ensure proper phase alignment and stable stereo imaging. This precision matching is essential for stereo techniques such as XY, ORTF, spaced pair, and Decca tree setups. The result is a natural stereo field with depth and clarity that translates well across studio monitors, headphones, and broadcast systems.

Custom Toroidal Transformers for Depth and Character

At the core of each microphone is a custom toroidal transformer that adds subtle harmonic richness and dimensionality while maintaining low distortion. Transformer-based design enhances tonal depth without sacrificing accuracy, making the matched pair well suited for acoustic instruments, strings, drum kits, percussion, and ensemble recording. The transformers contribute to a controlled low end and smooth high-frequency detail.

FET Circuit Design with Integrated 10 dB Pad

The FET preamp circuitry supports fast transient response and clean articulation across a wide dynamic range. The built-in -10 dB pad expands versatility by allowing the microphones to handle higher sound pressure levels without distortion. From delicate chamber music to aggressive snare drum attacks, the 013FET-M pair maintains clarity and composure.

Interchangeable Capsule System for Expanded Flexibility

The included cardioid capsules can be detached and replaced with optional hypercardioid or omnidirectional capsules, providing expanded polar pattern options without purchasing additional microphone bodies. These capsules are also compatible with the Soyuz SU-011 tube microphone system. This modular design allows engineers to adapt to various recording environments and stereo techniques while maintaining consistent tonal character.

Cream and Brass Finish with Professional Build Quality

Finished in cream and brass, the 013FET-M microphones combine distinctive aesthetics with durable construction. The compact small-diaphragm design allows precise placement in tight stereo configurations, drum setups, orchestral sections, and live stage environments. Built for long-term reliability, the matched pair performs consistently in both studio and touring applications.

Professional Stereo Solution for Studio Broadcast and Live Sound

Engineers seeking reliable small-diaphragm condenser microphones for stereo recording will benefit from the matched accuracy, transformer depth, and modular capsule compatibility of the 013FET-M. From classical recordings to modern productions, this stereo pair delivers controlled, detailed, and musically balanced results across a wide range of professional audio applications.
