ULTRAPHONO

 

UltraPhono replicates the wide bandwidth transparency Mobile Fidelity Sound Lab mastering engineers demand. Tim De Paravicini, the designer responsible for the Mobile Fidelity Gain2™ Ultra Analog cutting system, assisted with the internal circuitry to ensure your analog system at home faithfully reproduces the music buried in the grooves of your LPs. UltraPhono also includes an audiophile-quality Class A headphone amplifier for intimate listening enjoyment.

 

CLASS-A HEADPHONE AMPLIFIER

 

UltraPhono includes a powerful Class A headphone amplifier perfect for quiet nights when you want to keep the records spinning in private. And with a 31-step volume control built into the unit, all you need to do is directly plug-in your headphones and turn it up! It's the easiest way to achieve high-fidelity vinyl playback without speakers and electronics.

 

ADJUSTABLE GAIN AND LOADING

 

With selectable gain and loading, you will be able to tailor UltraPhono to match nearly any moving-magnet or moving-coil 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.
