• MC10-L: provides 10 times transformation ratio or 20db of gain
• MC16-L: provides 16 times transformation ratio or 24db of gain
• MC20-L: provides 20 times transformation ratio or 26db of gain
• MC26-L: provides 26 times transformation ratio or 28db of gain

The MC-L series moving coil step-up transformers are used to amplify the low level output signal from a moving coil cartridge bringing it to the appropriate level to drive a moving magnet phono preamp.

When terminated in 47k which is the standard input impedance of MM phono preamps the equivalent input impedance of each one would be: MC10-L 500 ohm / MC16-L 200 ohm / MC20-L 140 ohm / MC26-L 70 ohm.

If additional loading is needed, it can be done through the parallel input or output RCA connectors.

  The MC-L series transformers are extra large size single C-core double coil transformers using a proprietary amorphous core material. Special winding techniques were developed in order to minimize inter-winding capacitances and maintain wide frequency response. They are optimized sonically to be as invisible as possible.

The transformers are shielded with mu-metal and are potted in 10mm thick soft iron nickel coated enclosures providing immunity to outside magnetic fields and a quiet and noise free performance.
 

The MC-L step up transformers were developed in conjunction with the Ypsilon VPS100 phono preamp. They can be used with most of the moving coil cartridges. For optimum performance the MC-L transformers can be used within a specific range of cartridge output levels.

• MC10-L may be used with cartridges from 0.4 - 0.6mv • MC16-L may be used with cartridges from 0.3 - 0.4mv • MC20-L may be used with cartridges from 0.2 - 0.3mv
• MC26-L may be used with cartridges from 0.15 - 0.25mv
