Custom-Crafted Japanese Ribbon

The Fen-tone houses a 99.1% pure aluminum ribbon, custom-made in Japan. At 2.5-microns thick, the ribbon thickness is delicate enough to reproduce detailed audio but robust enough for everyday use. Ribbon purity is paramount for detail and frequency response; even slight impurities can dampen output and clarity, elevating the noise floor. The ribbon is also placed centrally in-between the magnet, eliminating the “bright” and “dark” side issue found on some ribbon mics.

Robust Neodymium Magnent

The ribbon inside the Fen-tone is suspended between the poles of a premium, heavy Neodymium magnet. While vintage original small-format ribbon mics like the B&O Fen-tone used AlNiCo magnets, Neodymium magnets are significantly stronger than AlNiCo magnets, and have become the new standard in premium ribbon microphone manufacturing. This allows for a more efficient conversion of sound energy to electrical signal in the ribbon microphone. Neodymium is also much less susceptible to degradation and will last much longer in regular use.

Custom, USA-Made CineMag Transformer

The Fen-tone utilizes a custom, American-Made CineMag output transformer. The transformer inside Fen-tone delivers the rich depth and character of the ribbon - including the lush mids and smooth highs. The CineMag inside the Fen-tone also helps the mic pair well with modern preamplifiers by achieving 300 ohm output impedance.

Hand-Tested, Elite Build Quality

Every single Fen-tone is meticulously hand tested & inspected at Warm HQ in Austin,TX by real musicians and engineers with passion for superior sound.
