1454M (150 : 670)

The Kraftwerk 1454M is a faithful replica of the original Marinair T1454 microphone input transformer, revered in legendary Neve consoles. Every detail—from winding geometry to inductance curve—is meticulously reproduced to honor the tonal heritage of 1970s British analog design.
 
Built for discerning engineers, the 1454M introduces subtle harmonic enhancement before amplification even begins, making it an essential foundation for musical color and presence.
