FLEA SM 204/23 – Handcrafted Multi-Pattern Tube Condenser Microphone

OVERVIEW

The FLEA SM 204/23 is a faithful recreation of one of the rarest and most fascinating studio microphones ever produced. Inspired by the legendary Siemens SM204/23, it has been meticulously developed to preserve the original microphone’s natural, detailed and exceptionally musical sonic character while bringing it into a modern recording environment. Every aspect of the design has received careful attention, from the mechanical construction and electronic circuitry to the capsule and transformer.

At the heart of the microphone is a faithful replica of the legendary V2545 output transformer, recreated with painstaking attention to the original design and materials. Combined with the FLEA CK12 capsule and self-biasing tube circuit, it produces a remarkably natural presentation with a rich midrange, smooth high frequencies and a solid, well-controlled low end. The self-biasing circuit also gives the microphone impressive composure and headroom when working with loud and dynamic sources.

Handcrafted in small production batches using premium-quality components, every FLEA SM 204/23 is individually measured, tested and inspected before leaving the factory. Its versatile multi-pattern operation makes it equally suited to vocals, spoken word, acoustic instruments and ambient miking, while its distinctive sonic character makes it an especially compelling choice for recording engineers and producers seeking the musicality and authenticity associated with classic studio microphones.
