The word “Ultra” is synonymous with Mobile Fidelity Sound Lab's philosophy. It represents our extreme pursuit of the highest level of reproduction of recorded sound—beyond the status quo—to provide music lovers with the experience of hearing the Original Master Recording in their home. Whether you're enjoying a standard LP or one of our UltraDisc One-Step limited-edition records, UltraDeck will deliver faithful playback of what's in the grooves.
Custom-developed and manufactured in the USA, the 10-inch Ultra tonearm uses smooth, high-quality ball bearings for low friction in the vertical and horizontal plane so all you hear is what is in the grooves. Cardas Audio wiring maintains signal purity from the headshell leads all the way through to the high-quality, gold-plated RCA connectors.
Our stepped-pulley AC motor provides excellent speed stability for pitch accuracy and rhythmic drive. The Delrin® pulley has two positions for 33 1/3 and 45 RPM speed selection. Motor vibrations are kept away from the platter and stylus by using advanced dampening materials that decouple the motor from the rest of the turntable.
UltraDeck features three aluminum plates carefully bonded to an MDF body to add mass and eliminate tonal coloration, maintaining the true sound found on the record.
Advanced technology, user-friendly features, and unflappable design elements ensure phenomenal playback—ultimately bringing the sound of Mobile Fidelity’s famous studio into your home.
Any vibration of the stylus that is not created by the grooves in the record is a distortion that will mask musical detail. Developed in conjunction with the engineering team at Harmonic Resolution Systems, the world leader in vibration isolation for audio equipment, the included MoFi anti-vibration feet isolate your turntable from bad vibrations.
UltraDeck features a massive 1.3-inch Delrin® platter. The increased mass creates blacker sonic backgrounds and a lower noise floor. Delrin® is a next-generation polymer developed by Dupont. In the world of audio, Delrin's® highly crystalline structure presents a wonderful impedance match to vinyl records, effectively grounding unwanted noise and keeping it away from the stylus.
Our hardened-steel inverted bearing system is designed for smooth, quiet rotational stability. The extremely low tolerance combination of steel, bronze, and sapphire—found in much more expensive turntables—will provide you many years of high-performance playback.
MoFi cartridges are designed by looking at where a record starts: On a cutting lathe like the model used at Mobile Fidelity Sound Lab. UltraTracker features a V-Twin dual-magnet generator that mirrors the layout of the cutting head that originally makes a record’s grooves. Employing two low-mass, powerful magnets aligned in a V formation parallel with the record grooves, UltraTracker features excellent tracking ability.
