Ortofon MC Transformer ST-M25 Step-Up Transformer

Ortofon ST-M25 Moving Coil transformer

Designed exclusively for the SPU Mono CG 25 Di MkII & SPU Mono CG 65 Di MkII.

The voltage output of these cartridges is too low to connect to the MM -INPUT terminal of amplifiers or phono-equalisers, resulting in inadequate sound volume. ST-M25 is specially designed to increase voltage by 12dB to match MM input of the ordinary amplifiers or phone-equalisers.

These cartridges supply the same monaural sound from both L/R channels, therefore L/R channels of the cartridges should be connected through ST-M25 and amplifier to the final output “speakers (L/R) ". You can enjoy robust sound of monaural sound coming from L/R speakers.
