rega RB-Titanium Tonearm Analogue Seduction

Introduction

The RB-Titanium tonearm is the most advanced and accurate production tonearm we have ever released. The entire tonearm structure is designed to have the minimum of mechanical joints whilst using the stiffest materials in all critical areas. The RB-Titanium achieves near frictionless movement horizontally and vertically whilst having no measurable free play in the bearing assemblies. The RB-Titanium uses our unique one-piece titanium vertical bearing housing and titanium vertical spindle assembly. The design is completed with a Tungsten balance weight shaft and balance weight.

Fitting your tonearm

The RB-Titanium will directly replace any other Rega tonearm that currently uses the 3 point mounting, without any modification. If fitting to another manufacturers product or an older Rega turntable (older RB models used a single nut fixing), the supplied template should be used as a guide to ensure correct position and alignment. With so many variants in turntable models, it is important to contact your turntable manufacturer if in any doubt before making any holes in plinths or arm boards. Before attempting to  fit the RB- Titanium arm to the turntable, it is important  to ensure that there is sufficient clearance beneath the turntable and that the arm does not hit any dust cover, top or sides. Having checked that there is sufficient clearance in all directions (including the maximum potential arm movement horizontal and vertical), the next step is to find the position of the centre of the arm mounting hole. The easiest way to do this will be to use the arm mounting template supplied.

Using the RB-Titanium tonearm

Firstly, ensure the cartridge fixings are orientated correctly according to the cartridge makers specification. Use the cartridge alignment protractor (supplied) to accurately set the position of the cartridge.

Note: When using any Rega cartridge featuring a three-point mounting system, overhang is automatically set.

With the cartridge correctly mounted and with the stylus guard removed, ensure that the tracking force dial (A) and bias adjustment (B) are set to zero. Adjust the balance weight (C) until the arm is “floating” with the stylus approximately 1mm clear of the record.

Note: It is normal for the arm to swing back towards the arm clip position even with the bias set at zero. Therefore, it is advisable to gently hold the arm bearing carrier (just below the tracking dial) thus preventing horizontal movement during the balancing procedure.

Once the arm is balanced, rotate the tracking force adjustment dial to the required tracking force. Numbers ‘0’ to ‘3’ are marked on the dial. If in doubt, it is advisable to use a tracking force that corresponds with the upper limits of the cartridge manufacturer’s range.

Set the bias adjustment slider to the same figure as the cartridge tracking force pressure quoted by your cartridge manufacturer. Simply push the bias adjustment slider into the required setting, using the dotted line as your reference.

Note: This is not critical and a figure between 1.0 & 1.5 will normally be suitable for moving magnet cartridges and 1.5 & 2.0 for most moving coil cartridges.

Arm mounting template guide

The supplied template is for mounting Rega three point fixing arms to other manufacturers turntables.

N.B. Protractor for cartridge alignment is also printed on the same template.

1. The template should be kept flat and not bent. The distance between the centre of the spindle and the centre of the arm hole is critical and must be 222mm. This template will help you check your positioning before you attempt fitting and drilling.

2. Position the other end of the template so that the clearance arc is within the rear and side edges of the turntable base (and the lid when closed). Also check that there is at least 250mm clearance from the centre of the hole to the inside front of the turntable.

3. Use a long pointed probe such as a needle and push it through the ‘arm hole centre’ on the template. Keep the needle perpendicular to the template and mark the position of centre on the turntable.

4. Having marked the centre, check again that if the arm is placed in this position it will clear the under side of the turntable and the lid. Also, check that the arm is in a satisfactory position to ensure easy operation and that the position is pleasing aesthetically. When you are certain that the arm hole centre is in its correct position (exactly 222mm from the record centre), you can drill the required arm hole.

5. The arm mounting pillar requires a diameter of 25mm which will provide adequate clearance for accurate fitting.
   You can then drill the three screw mounting holes as illustrated on the template. Make sure the arm is straight and the holes are correctly aligned before drilling.

6. With the holes drilled, you are now ready to fit the arm to the turntable. Ensure that you also follow the turntable manufacturer’s instructions regarding arm fitting. Each individual turntable manufacturer may have different requirements regarding positioning of the arm signal lead.

Hardware mounting pack

The supplied hardware mounting pack is for fitting the RBTitanium to other manufacturers turntables. The supplied kit is suitable for most arm boards or mounting to wood based plinths (real wood/MDF/chipboard). In some cases, you may need to source appropriate fixings for more exotic turntables.
