Description

Designed without compromise, every single component in the RG-1 is specially engineered and custom built, using the best possible materials and the highest standards of precision.

At the heart of any record player is its main bearing. Vertere RG‐1 record player utilises probably the highest precision bearing assembly designed for a record player. As a result the drive system can rotate the platter assembly absolutely smoothly and silently. Thus the record is presented to the tonearm and cartridge without any unwanted bearing noise.

One look at the record player motor assembly and the depth and innovativeness of its design become apparent. Using precision bearings to articulate the proprietary aluminium alloy motor housing keeps the motor continuously synchronous achieving constant belt tension. Simply put, it drives the platter at constant speed without interference.

RG-1 platter assembly is a unique two piece super precision machined aluminium alloy design that provides friction-only damping of the platter assembly.

The main platter has a critically designed surface profile on its top side that perfectly matches the underside of the reference platter insert. The two parts fit so precisely that the assembly creates a linearly damped, non‐resonant structure.

Offering peerless performance through uncompromising engineering, Vertere’s Record Player RG-1 Reference Groove incorporates innumerable carefully-considered design choices that make it supreme among turntables. The RG-1 includes a super precision main bearing and a two-piece non-resonant platter assembly to provide the most silent platform for the arm and the cartridge. The result is the ‘darkest’ background achievable from vinyl, against which every note played and every word sung comes to life.

The main bearing assembly comprises an aerospace-grade phosphor bronze housing, a super-precision tungsten carbide spindle and silicon nitride ball. The housing is machined and finished to the tightest of tolerances, with the bearing spindle sized to ensure the minimum gap possible between the spindle and the housing. The only contact is between the spindle and the precision ball supporting it at the bottom. The design of the bearing assembly ensures that the ball is housed absolutely central to the spindle. The main bearing is lubricated using Vertere’s proprietary bearing oil, L-1G, which ensures almost perfectly silent running. This lubricating oil is formulated with anti-friction, anti-foaming, water repellent and cooling agents for longevity and best performance. The unique design features of the main bearing, combined with the highest level of precision and attention to detail is mirrored in every other aspect of Vertere’s Record Player RG-1 Reference Groove.

On the main structure of the record player, the drive engine is a Swiss made synchronous motor. Vertere’s unique self-synchronising system for the motor keeps belt tension constant and also keeps any residual noise away from the platter. An external dedicated motor drive power supply unit, precisely tuned to each individual motor, ensures optimum power to the motor while keeping motor noise to a minimum.

Highest-quality cast acrylic has been chosen as the best material for the plinths of the record player, due to its consistent rigidity and naturally non-resonant properties. The plinths are CNC machined from different thicknesses of cast acrylic to their specific designed shapes and are critically isolated from each other. Isolation is provided by several unique suspension components, where every layer is designed to eliminate certain unwanted movements and vibrations – internal or external. The intricate design of the isolation components combined with the stable acrylic plinth structure provides the best possible platform for the tonearm, cartridge and the platter assembly. The result is an unparalleled and an unforgettable musical experience, every time you play a record on the RG-1.
