The MC1-H is a step-up transformer designed specifically for “high output” moving coil cartridges where the output voltage is significantly lower than a typical moving magnet cartridge (which is about 5mV). Cartidges in this category include the:

Denon DL-110
Denon DL-160
Benz Micro MC Silver
Hana EH
Hana SH
Roksan Shiraz

Any high output mc cartridge with an output voltage in the range 0.8mV to 1.8mV will benefit from an increased signal level and improved signal-to-noise ratio when used with the MC1-H. Cartridges in the range 1.8mV to 2.5mV may also benefit from the MC1-H.

Specifications:

  • Turns Ratio:  1:3.2
  • Voltage Gain:  10dB (x3.2)
  • Input Impedance*:  400 ohms
  • Optimum Load Impedance**:  47k + 150pF
  • Bandwidth:  5Hz - 36kHz (+0/-3dB)
  • Cartridge Compatibility (o/p):  0.8mV - 1.8mV (ideal), 1.8mV - 2.5mV (acceptable)
  • Cartridge Compatibility (imp.):  internal impedance <200 ohms
  • Dimensions:  60 x 155 x 92 mm
  • Weight:  580g

 *This is the load presented to the cartridge.
**This is the optimum load for the transformer, ie the input impedance of the phonostage that the MC1-H feeds into.
