MoFi Electronics UltraDeck+ Turntable with UltraTracker Cartridge
The MoFi Electronics UltraDeck+ is a high-performance belt-drive turntable supplied with a factory-installed UltraTracker moving-magnet cartridge. Designed in collaboration with turntable specialist Allen Perkins, it combines a 1.3-inch Delrin platter, isolated 300 RPM AC synchronous motor, 10-inch Ultra tonearm, hardened-steel inverted bearing and HRS-designed anti-vibration feet. The UltraTracker is pre-mounted and aligned for convenient setup while retaining the detailed, low-noise performance of the UltraDeck platform.

| Speed Selection |
Delrin Pulley |
| Power Consumption |
< 5 W |
The motor is mechanically isolated to keep motor vibration away from the platter and stylus. The two-position Delrin pulley provides the required drive ratios for 33⅓ and 45 RPM records.

| Weight |
3.08 kg / 6.8 lb |
The high-mass Delrin platter is designed to provide stable rotation and a low-noise mechanical interface with the record. Its increased mass contributes to the UltraDeck's stable playback platform and low mechanical noise floor.
Constrained-Layer Plinth
The UltraDeck uses a layered plinth structure consisting of three bonded aluminium plates and an MDF body. This constrained-layer construction adds mass while controlling mechanical resonance, helping prevent unwanted tonal coloration from the turntable structure.

| Cartridge Weight Range |
5–10 g |
The 10-inch straight-aluminium tonearm uses a gimbaled bearing arrangement for controlled vertical and horizontal movement. Its adjustment range accommodates cartridges weighing between 5 and 10 g, including the supplied UltraTracker.
UltraTracker MM Cartridge
The included UltraTracker is a dual-magnet moving-magnet stereo cartridge with a V-Twin generator, nude-elliptical stylus and well-damped billet-aluminium body. Its 3.5 mV output is designed for connection to a standard MM phono input. The cartridge is factory-installed and aligned on the UltraDeck+ for easier setup.

Cartridge & Tonearm Compatibility
The UltraTracker weighs 9.7 g, which falls within the Ultra tonearm's specified 5–10 g cartridge range. Its 3.5 mV output and 47 kOhm impedance make it suitable for a standard MM-compatible phono stage or PHONO input.
Bearing & Isolation
The UltraDeck uses a hardened-steel inverted bearing with a low-tolerance combination of steel, bronze and sapphire. HRS-designed anti-vibration feet further help isolate the record-playing mechanism from external vibration and acoustic energy.
