Main bearing assembly
At the heart of any turntable is its main bearing. Vertere RG‐1 turntable utilizes probably the highest precision bearing assembly designed for a turntable. 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.
Turntable motor
One look at the turntable 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.
Main reference platter
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.
Platter (underside)
The underside of the main platter is precision machined to provide a perfect fit to the main spindle block for accurate turning. It also has highest peripheral mass to maximize inertia to weight ratio. This ensures constant speed while eliminating undue pressure on the main bearing contact point. Maximum performance, maximum longevity.
Platter insert
Topside of the RG‐1 platter insert is precision machined to provide the bonding area for the 2mm cast Acrylic record interface disc.
The underside, on the other hand, is done as the precise fit to the topside of the main platter.
Six small stainless screws, from the underside ensure the two pieces are held perfectly together in non‐resonant state.
RG-1 Reference Motor Drive
RG-1 Reference Motor Drive with its most advanced control circuit design, implemented to its limits, allows us to achieve maximum performance from our world renowned RG-1 Reference Turntable & Reference Tonearm.
There are 7 speed adjustments via the front rotary knob allowing fine and exact ‘fixed’ speed selection of +/- 0.25%, 0.50%, 0.75%, 1.00%, 1.50%, 2.00% and 3.00% about the original 33 & 45 rpm.
RG-1 Motor Drive takes full control of the record player motor and provides the smoothest drive with minimum noise and distortion. The music that is extracted from the vinyl unbelievably resembles the original master that the record was cut from. Closest to the original master.
SG-1 Mk III Motor Drive
It is absolutely critical that the turntable motor is powered and controlled faultlessly to ensure a full and musical performance of the record player.
The SG-1 MkIII Motor Drive has new enhanced circuitry for speed accuracy, power delivery. The MkII utilises two fully protected output power devices with much improved control of the motor. The new output circuit provides the platter with constant and smoother drive. Elegant and simple to use with a ‘super charged’ engine under its bonnet!
RG-1 turntable dust cover
There is an optional dust cover that fully encloses the RG-1 while aesthetically complimenting the elegant lines and design of the turntable.
The main section covering the top, front and the back is a one piece 6mm clear cast acrylic providing support and rigidity with cut-outs for motor drive and tonearm cables. The sides are made from 3mm clear cast acrylic also including hand-grip cut-outs for easy placement and removal of the cover.
A Vertere emblem, laser engraved on the top adds the finishing touch to this elegant and practical record player dust cover.
Special Metallic Finishes
It was so important to ensure an uncompromising solution if any alternative finish were to be provided for the Reference RG-1 turntable. After extensive tests and design refinements, the RG-1 has now been made available in lustrous Metallic Black, Pearlescent White & Champagne special finishes at a premium.
Clear cast acrylic was carefully selected as plinth material to provide the most stable and acoustically suitable platform for RG-1’s critical components.
In order not to compromise performance and continue utilising this material, a special print and printing method was developed for these exceptional finishes. These beautiful finishes not only enhance the appearance of the RG-1 but also preserve its absolute reference performance.
The colour branded Vertere emblem printed on the top plinth adds the final finishing touch.
