The Erodion is Lyra's MC step-up transformer, and includes a number of proprietary design concepts and connection methods. Every part and assembly is custom made to create one of the finest products of its kind ever produced. We feel its performance is competitive with any step-up transformer regardless of price or aspiration.

Those who look for a "typical transformer sound" may be disappointed by the Erodion: it does not have a sound of its own, but comes very, very close to being a "straight wire with gain". Our goal was to create a neutral step-up device with a high-energy, direct signal path to highlight the strengths of the MC phono cartridge preceding it. Although especially designed for Lyra cartridges, it is usable with other low-impedance cartridges of 2 - 10 ohms. With a gain of 26 dB the Erodion has been designed to step the output of low output, low impedance MC cartridges up to the standard 10 kohms ~ 47 kohms MM phono inputs of preamplifiers and phono stages.

An MC step-up transformer is fundamentally very different from an amplification stage. When a low-impedance MC cartridge is connected directly to a high gain RIAA preamplifier, the impedance loading value can be set to any value between 100 ohms to 47 kohms, however, an MC step-up transformer is designed as an impedance matching device between an MC cartridge and a 10 kohms ~ 47 kohms MM level RIAA input.

  • Gain : 26 dB (20 times) (when cartridge's internal impedance is 2 - 10 ohms and MM level RIAA preamplifier or phono stage presents 47 kohms load)
  • Load of MM RIAA preamplifier or phono stage : 10 kohms ~ 47 kohms Useable MC phono cartridges: internal impedance range of 2 ohms - 10 ohms
  • Load of MM RIAA preamplifier or phono stage : 10 kohms ~ 47 kohms Useable MC phono cartridges : internal impedance range of 2 ohms - 10 ohms
  • Useable MC phono cartridges : internal impedance range of 2 ohms - 10 ohms
  • Frequency range : 10 - 100,000 Hz (when above conditions are met)
  • Feet : three stainless steel spikes
  • Net size : (W x D x H) 150 mm x 115 mm (128 mm incl. connectors) x 65 mm (78 mm incl. feet)
  • Net weight : Approximately 2500 grams (5.5 US pounds)
  • (The Erodion does not contain any electrical power supply, and it does not require any power input of any kind.)
