Rothwell MC1 step-up transformer for low output MC cartridges from 0.25 to 0.7 mV with source impedance below 30 ohms. Read more.
The Rothwell MC1 moving coil step-up transformer is the brand’s most affordable solution for using low output moving coil cartridges with a suitable MM phono input. It is designed for vinyl listeners who want a practical, well-matched way to raise the tiny signal from an LOMC cartridge before it reaches the phono stage. As an entry point into Rothwell step-up transformers, the MC1 is ideal for carefully built turntable systems where compatibility, low noise and musical clarity matter.
Its 1:12.9 turns ratio makes the Rothwell MC1 suitable for many low output moving coil cartridges currently available. It is intended for cartridges with output voltages from 0.25 mV to 0.7 mV and source impedances below 30 ohms. Used in the right system, a passive step-up transformer can help the phono stage receive a stronger signal while preserving the character of the cartridge. This makes the MC1 a practical choice for listeners who want a straightforward MC cartridge upgrade path.
The Rothwell MC1 can be used between a turntable fitted with a compatible LOMC cartridge and an MM phono preamplifier, integrated amplifier or receiver with a moving magnet phono input. Matching remains important, so cartridge output and source impedance should always be checked before purchase. For systems that meet these requirements, the MC1 offers a focused and sensible way to enjoy moving coil playback; contact us for guidance and find the right match for your vinyl setup.
