Description
The Rothwell Audio MC1-H Moving Coil Step Up Transformer is engineered specifically for high-output moving coil cartridges, not low-output designs. It is intended for cartridges whose output voltage is lower than a typical moving magnet cartridge but higher than traditional low-output moving coil models.
Examples include cartridges such as the Denon DL 110, Denon DL 160, Benz Micro MC Silver, Hana EH, Hana SH, and Roksan Shiraz. These cartridges often sit in a performance gap where they cannot fully realise their potential through a standard moving magnet phono stage alone.
The MC1-H increases signal level while improving signal-to-noise performance, allowing high-output moving coil cartridges to deliver greater clarity, dynamic expression, and musical realism when connected to a moving magnet phonostage.
Unlocking Musical Detail and Dynamic Expression
Rather than simply boosting signal voltage, the Rothwell Audio MC1-H Moving Coil Step Up Transformer is designed to preserve the subtle musical qualities that make moving coil cartridges so appealing. Fine low-level detail, fast transients, and natural dynamics are maintained through a carefully engineered passive amplification stage.
High-output moving coil cartridges benefit from improved tonal richness, better separation, and enhanced spatial definition when used with the MC1-H. This allows listeners to enjoy the characteristic warmth and resolution of moving coil designs without the need for a dedicated moving coil phonostage.
The result is a more engaging and emotionally convincing presentation that reveals the full character of vinyl recordings while maintaining compatibility with existing moving magnet-based systems.
Precision Lundahl Transformer Technology
At the core of the Rothwell Audio MC1-H Moving Coil Step Up Transformer is a precision transformer manufactured by Lundahl in Sweden. These transformers are renowned for their wide bandwidth, low distortion, and exceptional consistency.
Optimised specifically for use with high-output moving coil cartridges feeding moving magnet phonostages, the design features carefully balanced primary and secondary windings that minimise hum and external interference. Inter winding capacitance is kept extremely low to preserve high frequency extension and phase accuracy.
Carefully chosen loading networks ensure a clean transient response without ringing or coloration. This level of engineering allows the MC1-H to deliver a natural, open, and lifelike sound that remains faithful to the original recording.
Technical Performance and Build Quality
The Rothwell Audio MC1-H Moving Coil Step Up Transformer offers a step-up ratio of 1 to 20, delivering a voltage gain of 26 dB.
It is optimised for high-output moving coil cartridges with output levels typically between 0.8 mV and 1.8 mV, while cartridges up to 2.5 mV may also benefit. Input impedance is set at 100 ohms, with an optimum load of 47k plus 150 pF to ensure broad compatibility with moving magnet phonostages.
The frequency response extends from 8 Hz to 75 kHz within tight tolerances, preserving the full audio spectrum. Housed in a solid, well-shielded enclosure, the MC1-H offers reliable low-noise performance and long-term durability for serious vinyl enthusiasts.
