Main bearing assembly
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.
Record player motor
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.
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 maximise 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 Record Player & 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.
Tempo Motordrive
It is absolutely critical that the record player motor is powered and controlled faultlessly to ensure a full and musical performance of the record player.
The new Tempo takes control of the record player motor and provides it with a smoother drive with lower noise and lower distortion. Its internal circuit as with the reference motor drive is uniquely microprocessor based providing a pure sine wave in the digital domain and then converted to analogue via an on-board DAC. Two waveforms are derived, a cosine and a sine, which are then amplified using two bridged amplifiers to power the motor.
SG-1 Record Player dust cover
There is an optional dust cover that fully encloses the SG-1 while aesthetically complimenting the elegant lines and design of the record player.
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.
