On top of the main plinth, the Signature 12 uses a mass-loaded magnetic sub-chassis, which is perfect for reducing resonance and noise transfer to the cartridge. The large, heavy main platter rides on this sub-chassis, rotating on an inverted ceramic main bearing with almost no friction at all. The main platter itself is machined from a specially selected, resonance-optimised metal alloy, which is internally lined with damping material and topped with melted vinyl records. The turntable is finished with the Signature Record Puck as part of the package.
The external drive motors are powered by a high-tolerance speed controller, built into the chassis in the form of a purpose-designed computer. The dual-motors then drive a flywheel mechanism that allows for a resonance-free drive system. The computer accomodates both 33 and 45 rpm speeds, with the ability to incrementally adjust the speed for pin-point timing.
The striking 12" Signature tonearm is a unique Pro-Ject design. Unlike anything else in the range, Pro-Ject's Signature Tonearms are made from different metal and aluminium alloys and are tooled with ultra-precise diamond cutters on CNC machinery. Inside the tonearm tube, damping material is meticulously applied to add mass and acoustic integrity, but in order to keep the iconic toe-tapping sound that Pro-Ject is associate with, the tube is mounted on a special, oil-damped Uni-Pivot bearing. To further aid exact set-up, Signature Tonearms can have the VTA, Azimuth and Overhang easily adjusted. The use of a detachable headshell allows the Signature 12 to easily accomodate a variety of high-end cartridges, whether they're for a specific use (such as Mono recordings) or to suit a certain musical style or genre.
The Signature 12 is like nothing else out there, and it showcases Pro-Ject Audio Systems' ability to deliver a true, high-end sound without comparison.
