INTRODUCTION The RP8 has been designed and engineered to achieve outstanding performance way beyond the expectations of a product at this price point. Excellent build quality, reliability and ease of use combine to make a product which, if used correctly, will offer you a lifetime of musical enjoyment. The RP8 takes Rega’s design philosophy further than ever before.
TURNTABLE DESIGN & MYTHOLOGY Today there are many approaches to Hi-Fi design which follow established and informed engineering or electronic principles. Amplifier and loudspeaker design has been well documented over the years with excellent technical publications. These subjects have been based on tried and tested acoustic criteria and many computer software programs now exist that enable a near amateur to design a passable working loudspeaker based on known acoustic and mathematical parameters.
DESIGN AND INNOVATION 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.
Practically this means keeping as much of the mass to the outside rim of the glass platter to create more flywheel effect while keeping the inside of the platter as light as possible without sacrificing stiffness. The RP6 was the first Rega turntable to use a precision engineered glass ring laminated to the outside using modern CNC techniques to ensure concentricity.
MOTOR The motor is a high specification, 24V twin phase synchronous unit which has a board mounted anti vibration circuit hand tuned to each motor. It is controlled by Rega's unique and innovative TTPSU power supply. The motor drives the CNC machined pulley, sub platter and hub-bearing assembly via the twin belt drive. TTPSU - POWER SUPPLY Your RP8 turntable motor is hand tuned and matched to the supplied TTPSU, this ensures the maximum reduction of motor noise and vibration is achieved.
TONEARM The RB808 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 RB808 has improved bearings and a tightened spindle fit tolerance over previous models (each bearing is individually selected to find the perfect match for the chosen spindle). This is a Rega developed method of increasing the amount of detail retrieved from the record surface.
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 RP8 can be used without the outer frame if so desired.
SETTING UP AND POSITIONING YOUR RP8 TURNTABLE. Always take great care when unpacking the turntable. Extra care must be taken if your RP8 is supplied with a cartridge factory fitted so as not to damage the stylus. Place the turntable on a sound and level surface. The RP8 inner plinth sits within the outer frame, locates and self centralises via three rubber triangulated ‘o’ rings.
TTPSU Connect the turntable power interconnect between the TTPSU and the turntable. Make sure the PS1 mains transformer is plugged in and connected to the 24V AC input terminal in the back of the TTPSU. Switch the mains power on. To minimise the risk of hum pick up by the cartridge, the power supply should be situated as far from the turntable as the interconnect cable will allow.

CARE OF YOUR TURNTABLE Mount the turntable on a rigid, level surface. Avoid mounting on hollow or heavy cabinets or anything mounted on a flexible wooden floor. The Rega turntable support is the ideal solution. Keeping the lid closed while playing records will prevent dust falling on to the record surface and should make cleaning unnecessary. Depending on the room environment and ambient temperature, playing with the lid open may offer sonic improvements.
Do not use any polish on the turntable or lid. To clean, wipe gently with a soft cotton duster (slightly damp only if required). Rega turntables are designed to optimise performance for music reproduction and therefore no compromises have been made to give quick start times. The normal time taken for full speed to be reached is between 2 and 5 seconds. Warning: Any attempt to repair or modify the turntable or tonearm by persons other than Rega approved personnel may invalidate the guarantee.
