1452L (2400 : 600)
The Kraftwerk 1452L is a dedicated line-level input transformer modeled after the legendary Marinair T1452. Designed to bridge signal paths with precision and warmth, it provides a 2:1 step-down ratio ideal for feeding transformer-balanced mic preamps from high-level sources.
Its elegant voicing and headroom-friendly design allow engineers to retain clarity while subtly enhancing harmonic texture — a perfect balance of fidelity and character.
