MoFi StudioPhono: Perfect phono stage for your record player

The MoFi Electronics StudioPhono phono preamplifier has a wide bandwidth, which was specially developed by engineers working at the Mobile Fidelity Sound Lab. Tim De Paravicini, the developer behind the Mobile Fidelity Gain2 Ultra analog disc cutting system, helped create the internal circuitry to ensure your system plays the music from your vinyl records at its best.

With gain and load selection, you can tailor the MoFi Electronics StudioPhono phono stage to fit virtually any MM or MC cartridge. An easily accessible switch panel can be found on the underside of the device.


At the top of the device there are two buttons to turn on/off the mono or subsonic filter mode. If you’re a fan of mono vintage recordings or reissues such as the Beatles or Mobile Fidelity Sound Lab Bob Dylan, the mono mode is a godsend. This will improve the stability of the sound picture and create a richer sound.

MoFi Electronics StudioPhono and UltraPhono phono stages are specifically designed to work with most MM and MC heads. If you are using MC heads, you will need to adjust the phono preamp settings for best results. Locate the DIP switches located on the bottom panel. Each switch is mirrored for left and right channels. Start by selecting each DIP switch for your head’s recommended impedance level, as shown in the Input Impedance Settings chart. Then select the best gain for your cartridge using the gain settings chart and set the DIP switches accordingly. For MM heads start at 40 dB, for MC heads start at 60 dB. An additional 6 dB can be added via DIP switches 1 and 12.
