RP10 Custom power supply
Housed in Rega'svibration and speed control circuit dedicated to running the 24v low noise motor. The speed and control of the motor is achieved by using a new DSP (Digital Signal Processing) generator built upon a high stability crystal. This device will divide the accurate square wave from the crystal to the exact frequency required to turn the platter at the selected speed. The DSP core will also generate a near perfect sinusoidal waveform to power the motor. Factory set vibration and speed adjustments are then made to the power supply to tune the motor for optimal performance.
The RB2000 tonearm is packed with new features pushing the boundaries of tonearm design. As with all Rega tonearms, each one is meticulously hand built by a team of highly skilled technicians. The RB2000 uses improved bearings with each one being hand selected to be an interference fit with the paired spindle matching both the inside and outside diameters.
This is a Rega developed method of increasing the amount of detail retrieved from the record surface, designed specifically to maximise performance of the tonearm and cartridge. The entire tonearm structure is designed to have the minimum of mechanical joints whilst using the stiffest materials in all critical areas. The tolerance of the RB2000 tonearm is so tight that no adhesive is used at any point throughout the construction.
A brand new low mass, precision engineered, vertical bearing assembly has been manufactured to further compliment the inherent design philosophy of the RP10 turntable. The RB2000 uses the latest award winning Rega arm tube. Each one is meticulously hand polished (keeping mass to an absolute minimum) and has been completely redesigned to redistribute mass and further reduce stresses and resonances. This advanced design tube increases the stiffness and rigidity of the overall assembly, whilst reducing stress on the bearings even further.
Magnesium and Phenolic
Dual bracing - A super lightweight plinth combined with a double brace mounted specifically where the increased rigidity is required (between the tonearm mounting and the main hub bearing) forms a structurally sound "stressed beam" assembly. This design prevents energy absorption and unwanted resonances which will add un-natural distortions to the music.
The RP10 takes our double brace technology to the next level. Not content with an unprecedented stiffness to mass ratio, Rega have obsessively reduced any resonant properties by using two different materials for the new stressed beam. The top layer is magnesium and the bottom layer is phenolic (two of the lightest and stiffest materials available).
Incorporating two different materials into the brace structure lowers their ability to pick up unwanted airborne vibrations. Simply put, different materials have different natural resonances. By using two different materials together they decrease the natural frequency of each other by self-damping.
N.B Rega will always use materials in the form that achieves maximum performance. The raw magnesium will develop patina and change colour over time, this is perfectly normal. Coating to prevent this discoloration would affect sonic performance therefore the material remains raw. If you wish to bring the shine back to your magnesium top brace careful use of metal polish will restore it to its original condition.
Super flywheel effect ceramic platter
The RP10 uses a custom ceramic flywheel effect platter. The platter is produced from ceramic oxide powder which is compressed, fired and diamond cut to ensure perfect accuracy and flatness across the surface. The new platter features a modified construction over the previous P9 version with improved coupling to the sub platter.
24v Low noise motor
The motor is a high specification, 24v twin phase synchronous unit. It is controlled by Rega's unique and innovative RP10-PSU power supply. The motor drives the CNC machined pulley, sub platter and hub-bearing assembly via the twin belt drive. Each motor is individually hand tuned to its own custom power supply in the factory to minimise vibration, motor noise and ensure optimum performance.
Skeletal plinth design with polyolefin foam core
Controversially, Rega has always researched methods of producing light but stiff and rigid plinths. The technology is simple: unwanted noise at microscopic levels is developed by the turntable motor and main bearing.
The plinth can also pick up airborne vibration from the music. From the beginning in the 1970's, Rega pioneered the use of a stressed skin structure for the plinth. This uses two layers of phenolic resin with a lightweight particle or fibre board sandwiched between the skins.
This technique has been used in many applications where stiff, light structures are needed such as an aircraft wing or a Formula 1 chassis. The current increase in interest in turntables has allowed Rega to research and develop higher technology structures for the customer who is happy to pay a little more for higher sound quality.
The all new RP10 turntable utilises a unique new stressed skin structure produced from thin phenolic skins, sandwiching a featherweight nitrogen expanded, closed cell, polyolefin foam core. This material has been developed exclusively for Rega over a three year period. The RP10 plinth is 7 times lighter than the weight of the original Planar 3 plinth. Rega has added even more stiffness in the crucial area between the arm and the main bearing.
De-coupled outer frame and dust cover
A common problem for many skeletal design turntables is the inability to incorporate an effective dust cover into the design. We have constructed an outer frame that minimises contact between the inner and outer plinth. The only points of contact are three location devices on the feet which centralises the inner and outer plinths perfectly. This makes set-up extremely easy and allows the use of a dust cover. The RP10 can be used without the outer frame if so desired.
