Mobile Fidelity StudioPhono™

Phono preamplifier for moving magnet and moving coil cartridges


The MoFi StudioPhono is a phono preamp that has been engineered to work with a wide array of Moving Magnet (MM) and Moving Coil (MC) phono cartridges. The StudioPhono is factory set to operate with most high-output moving magnet (MM) and  moving coil (MC) phono cartridges. If you are using a low-output moving coil (MC) cartridge, you will need to adjust the phono preamplifier's settings for best results.

Adjustable Gain & Loading: With selectable gain and loading, you will be able to tailor the MoFi StudioPhono to match nearly any moving-magnet (MM) or moving-coil (MC) cartridge on the market. A readily accessible bank of toggle switches can be found on the unit's underside to quickly make adjustments without the need for any tools.

Gain: selectable gain of 40dB, 46dB, 60dB, and 66dB for MM or MC

Load Impedance: adjustable load impedance of 75, 100, 500, 1k, 10k, or 47k ohms for MM, MM is fixed at 47k ohms

Mono & Subsonic Filters: Two selectable toggle buttons on the top of the unit can engage a Mono or Subsonic filter mode. The Mono mode will improve image stability and generate a richer tone for mono-recorded vinyl. The Subsonic filter controls low frequencies below 20Hz preventing ultra low rumble.

Stereo RCA Input & Output: The MoFi StudioPhono is outfitted with a gold-plated stereo RCA input and output. The input connects to your turntable's output, while the output connects to an analog input on your AV receiver, stereo receiver, or integrated amplifier. NOTE: This phono preamp does not come with an RCA cable to connect to your receiver or amp.

External Power Supply: The included external power supply will need to be plugged into an AC wall outlet, surge protector, or power conditioner.

Placement: The StudioPhono will operate at its best when properly installed in a location that's free from magnetic fields like those generated by equipment with power transformers (such as an amplifier), and within a reasonable distance between your turntable and audio component(s).
