FLEA M 251 f Large-Diaphragm FET Condenser Microphone - Classic Tone, Modern Reliability

The FLEA M 251 f is a groundbreaking solid-state reinterpretation of the legendary Telefunken ELA M 251, blending its iconic sound with the clarity and reliability of FET technology. Featuring a meticulously crafted CK12 capsule replica and an identical T14/1 transformer clone, it delivers the warmth, richness, and versatility of the original tube design without the need for an external power supply or tube maintenance. With cardioid, figure-eight, and omnidirectional polar patterns, the M 251 f is ideal for vocals, acoustic instruments, and studio applications, offering a transparent, low-noise performance in a vintage-inspired package.

Classic Sound with FET Precision

The FLEA M 251 f captures the soul of the ELA M 251 with a custom FET circuit, providing a slightly more transparent sound while retaining the mic’s signature warmth and smoothness. Powered via +48V phantom power, it eliminates tube maintenance and offers an enhanced signal-to-noise ratio, ensuring pristine recordings. The handcrafted CK12 capsule, a faithful replica of the original, delivers exceptional detail and clarity, while the T14/1 transformer clone preserves the iconic tonal balance across its versatile polar patterns.

Versatile Recording Applications

With three selectable polar patterns—cardioid, figure-eight, and omnidirectional—the M 251 f adapts to diverse recording scenarios. Use cardioid for focused vocal or voice-over tracks, figure-eight for stereo techniques or rejecting unwanted sound, and omnidirectional for capturing ambient instruments like acoustic guitars or drum overheads. Its low-noise FET design and robust 140 dB max SPL (based on similar FET mics) make it a reliable choice for both delicate and high-energy sources in professional studios.

Iconic Design, Modern Craftsmanship

Handcrafted in Slovakia with gold-plated connectors for superior conductivity, the M 251 f combines vintage aesthetics with modern durability. Its precise construction ensures long-term reliability, while the absence of tubes simplifies operation without sacrificing the classic 251 character. The included handcrafted wooden box, swivel stand mount, and high-quality cable complete a premium package designed for discerning engineers and artists.
