Rothwell MC1-H step-up transformer with 10 dB gain for high output MC cartridges into an MM phono stage. Read more.
The Rothwell MC1-H is a step-up transformer designed for high output moving coil cartridges rather than traditional low output MC models. It is a focused solution for music lovers who use a cartridge with a lower signal level than a typical moving magnet cartridge, but who still want to feed an MM phono stage in a sensible way. Cartridges around 0.8 mV to 1.8 mV, including models such as the Denon DL-110, Hana EH, Hana SH and Benz Micro MC Silver, are the intended match.
The MC1-H uses a low turns ratio of 1:3.2 to provide approximately 10 dB of voltage gain before the signal reaches the MM phonostage. This can raise the cartridge output to a more usable level and may improve the signal-to-noise ratio in systems where the MM input alone is slightly underpowered for a high output MC cartridge. With a stated input impedance of 400 ohms, the Rothwell MC1-H is purpose-built for this specific cartridge category rather than being a general MC transformer.
For vinyl systems built around a quality MM phonostage, the Rothwell MC1-H can be a compact and logical upgrade. It is especially relevant for cartridges such as Denon DL-160 or Roksan Shiraz when the output level benefits from extra passive gain. Use well-shielded interconnects, keep the transformer away from power supplies where possible, and match it with a suitable high output MC cartridge. Explore the MC1-H if you want your MM phono input to work more comfortably with high output MC.
