Moving coil step up transformers
The MC 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.
The MC5 provides 5 times transformation ratio or 14db of gain
The MC10 provides 10 times transformation ratio or 20db of gain.
The MC16 provides 16 times transformation ratio or 24db of gain.
The MC20 provides 20 times transformation ratio or 26db of gain.
When terminated in 47k which is the standard input impedance of MM phono preamps the equivalent input impedance of each one would be:
MC5 2K ohm
MC10 500 ohm
MC16 200 ohm
MC20 140 ohm
If additional loading is needed, it can be done through the parallel input RCA connectors.
The MC series transformers are 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 transformers were developed in conjunction with the VPS100 phono preamp. They can be used with most of the moving coil cartridges. For optimum performance the MC transformers can be used within a specific range of cartridge output levels.
MC5 may be used with cartridges from 0,8-1,2mv
MC10 may be used with cartridges from 0.4-0.6mv
MC16 may be used with cartridges from 0.3-0.4mv
MC20 may be used with cartridges from 0.2-0.3mv
