Product details

MoFi UltraPhono combines a moving-magnet and moving-coil phono stage with a Class A headphone amplifier. It can feed a conventional amplifier through its RCA outputs or play records directly through compatible headphones.

Cartridge matching

Underside DIP switches select 40, 46, 60 or 66 dB of gain and cartridge loading from 75 Ω to 47 kΩ. Moving-magnet input capacitance is 100 pF. A switchable mono mode combines the channels for mono records, and a subsonic filter reduces low-frequency content below 20 Hz.

Headphone listening

The headphone output has a 31-step volume control with 2 dB increments and a push-to-mute function. A supplied external power supply keeps mains conversion outside the enclosure. Stereo RCA inputs, outputs and a grounding terminal connect the turntable and playback system.
